In case of incompatibility a non fatal warning will be emitted and FALSE will be returned. hDriver — the handle of the driver with whom the lists of creation option must be validated. papszCreationOptions — the list of creation options.

An array of strings, whose last element is a NULL pointer. TRUE if the list of creation options is compatible with the Create and CreateCopy method of the driver, FALSE otherwise. This is the string that can be passed to the GDALGetDriverByName function. the short name of the driver. The returned string should not be freed and is owned by the driver. the long name of the driver or empty string. the URL to the help that describes the driver or NULL. Return the list of creation options of the driver used by Create and CreateCopy as an XML string.

an XML string that describes the list of creation options or empty string. The return must be freed with GDALDeinitGCPs followed by CPLFree. Due to imprecision in the calculations the fit algorithm will often return non-zero rotational coefficients even if given perfectly non-rotated inputs.

A special case has been implemented for corner corner coordinates given in TL, TR, BR, BL order. So when using this to get a geotransform from 4 corner coordinates, pass them in this order.

Starting with GDAL 2. If set to YES, then bApproxOK will be overridden with TRUE. The default is 0. padfGeoTransform — the six double array in which the affine geotransformation will be returned.

bApproxOK — If FALSE the function will fail if the geotransform is not essentially an exact fit within 0. This function will invert a standard 3x2 set of GeoTransform coefficients. This converts the equation from being pixel to geo to being geo to pixel. The resulting geotransform is the equivalent to padfGT1 and then padfGT2 being applied to a point. padfGTOut — the output geotransform, six values, may safely be the same array as padfGT1 or padfGT2. This is for example the case of the GTiff format this is not a exhaustive list.

GDALMajorObject::SetMetadata , GDALDataset::SetMetadata , GDALRasterBand::SetMetadata. GDALMajorObject::SetMetadataItem , GDALDataset::SetMetadataItem , GDALRasterBand::SetMetadataItem. For shared datasets opened with GDALOpenShared the dataset is dereferenced, and closed only if the referenced count has dropped below 1. This method establish an asynchronous raster read request for the indicated window on the dataset into the indicated buffer.

The parameters for windowing, buffer size, buffer type and buffer organization are similar to those for GDALDataset::RasterIO ; however, this call only launches the request and filling the buffer is accomplished via calls to GetNextUpdatedRegion on the return GDALAsyncReader session object. Once all processing for the created session is complete, or if no further refinement of the request is required, the GDALAsyncReader object should be destroyed with the GDALDataset::EndAsyncReader method.

Note that the data buffer pData will potentially continue to be updated as long as the session lives, but it is not deallocated when the session GDALAsyncReader is destroyed with EndAsyncReader. It should be deallocated by the application at that point. nXOff — The pixel offset to the top left corner of the region of the band to be accessed. This would be zero to start from the left side. nYOff — The line offset to the top left corner of the region of the band to be accessed. This would be zero to start from the top.

pBuf — The buffer into which the data should be read. It is organized in left to right,top to bottom pixel order. Spacing is controlled by the nPixelSpace, and nLineSpace parameters. nBufXSize — the width of the buffer image into which the desired region is to be read, or from which it is to be written. nBufYSize — the height of the buffer image into which the desired region is to be read, or from which it is to be written.

eBufType — the type of the pixel values in the pData data buffer. Note band numbers are 1 based. This may be NULL to select the first nBandCount bands. nPixelSpace — The byte offset from the start of one pixel value in pData to the start of the next pixel value within a scanline.

If defaulted 0 the size of the datatype eBufType is used. nLineSpace — The byte offset from the start of one scanline in pData to the start of the next. nBandSpace — the byte offset from the start of one bands data to the start of the next. papszOptions — Driver specific control options in a string list or NULL. Consult driver documentation for options supported.

Use GDALDatasetRasterIOEx if 64 bit spacings or extra arguments resampling resolution, progress callback, etc. are needed. GDALDataset::BuildOverviews and GDALBuildOverviews. This function copies the complete raster contents of one dataset to another similarly configured dataset.

The source and destination dataset must have the same number of bands, and the same width and height. The bands do not have to have the same data type. This function is primarily intended to support implementation of driver specific CreateCopy functions.

band interleaved read and write access pattern this does not modify the layout of the destination data. This function copies the complete raster contents of one band to another similarly configured band. The source and destination bands must have the same width and height.

This function will generate one or more overview images from a base image using the requested downsampling algorithm. Its primary use is for generating overviews via GDALDataset::BuildOverviews , but it can also be used to generate downsampled images in one file from another outside the overview architecture. The full set of resampling algorithms is documented in GDALDataset::BuildOverviews. The returned layer remains owned by the GDALDataset and should not be deleted by the application.

Returns true if the layer at the specified index is deemed a private or system table, or an internal detail only. If this function is supported the ODsCDeleteLayer capability will test TRUE on the GDALDataset. This function attempts to create a new layer on the dataset with the indicated name, coordinate system, geometry type. The papszOptions argument can be used to control driver specific creation options. These options are normally documented in the format specific documentation.

include "gdal. GDALDatasetTestCapability hDS , ODsCCreateLayer { pszName — the name for the new layer.

This should ideally not match any existing layer on the datasource. hSpatialRef — the coordinate system to use for the new layer, or NULL if no coordinate system is available. The driver might only increase the reference counter of the object to take ownership, and not make a full copy, so do not use OSRDestroySpatialReference , but OSRRelease instead when you are done with the object. eGType — the geometry type for the layer. Use wkbUnknown if there are no constraints on the types geometry to be written.

NULL is returned on failure, or a new OGRLayer handle on success. This function creates a new layer, duplicate the field definitions of the source layer and then duplicate each features of the source layer.

The source layer may come from another dataset. The returned feature becomes the responsibility of the caller to delete with OGRFeature::DestroyFeature. Depending on the driver, this method may return features from layers in a non sequential way.

This is what may happen when the ODsCRandomLayerRead capability is declared for example for the OSM and GMLAS drivers. When datasets declare this capability, it is strongly advised to use GDALDataset::GetNextFeature instead of OGRLayer::GetNextFeature , as the later might have a slow, incomplete or stub implementation. The default implementation, used by most drivers, will however iterate over each layer, and then over each feature within this layer.

This method takes into account spatial and attribute filters set on layers that will be iterated upon. Depending on drivers, this may also have the side effect of calling OGRLayer::GetNextFeature on the layers of this dataset. pdfProgressPct — a pointer to a double variable to receive the percentage progress in [0,1] range , or NULL.

On return, the pointed value might be negative if determining the progress is not possible. pfnProgress — a progress callback to report progress for GetNextFeature calls that might have a long duration and offer cancellation possibility, or NULL. One of the following dataset capability names can be passed into this function, and a TRUE or FALSE value will be returned indicating whether or not the capability is available for this object.

ODsCCreateGeomFieldAfterCreateLayer : True if the layers of this datasource support CreateGeomField just after layer creation. ODsCEmulatedTransactions : True if this datasource supports transactions through emulation. ODsCRandomLayerRead : True if this datasource has a dedicated GetNextFeature implementation, potentially returning features from layers in a non sequential way.

ODsCRandomLayerWrite : True if this datasource supports calling CreateFeature on layers in a non sequential way. The define macro forms of the capability names should be used in preference to the strings themselves to avoid misspelling. The result of an SQL query is either NULL for statements that are in error, or that have no results set, or an OGRLayer pointer representing a results set from the query. Note that this OGRLayer is in addition to the layers in the data store and must be destroyed with ReleaseResultSet before the dataset is closed destroyed.

For more information on the SQL dialect supported internally by OGR review the OGR SQL document. Some drivers i. Oracle and PostGIS pass the SQL directly through to the underlying RDBMS. Starting with OGR 1.

pszDialect — allows control of the statement dialect. If set to NULL, the OGR SQL engine will be used, except for RDBMS drivers that will use their dedicated SQL engine, unless OGRSQL is explicitly passed as the dialect. an OGRLayer containing the results of the query.

Deallocate with GDALDatasetReleaseResultSet. This function can be safely called from any thread pending that the dataset object is still alive. Driver implementations will make sure that it can be called in a thread-safe way. This might not be implemented by all drivers.

At time of writing, only SQLite, GPKG and PG drivers implement it. This function should only be used to deallocate OGRLayers resulting from an ExecuteSQL call on the same GDALDataset. Failure to deallocate a results set before destroying the GDALDataset may cause errors. This function operate exactly as GDALDatasetSetStyleTable except that it assumes ownership of the passed table. This function operate exactly as GDALDatasetSetStyleTableDirectly except that it assumes ownership of the passed table.

All changes done after the start of the transaction are definitely applied in the datasource if CommitTransaction is called. They may be canceled by calling RollbackTransaction instead. Datasets that support transactions will advertise the ODsCTransactions capability.

Use of transactions at dataset level is generally preferred to transactions at layer level, whose scope is rarely limited to the layer from which it was started. In case StartTransaction fails, neither CommitTransaction or RollbackTransaction should be called.

If an error occurs after a successful StartTransaction , the whole transaction may or may not be implicitly canceled, depending on drivers. In any case, in the event of an error, an explicit call to RollbackTransaction should be done to keep things balanced. Some drivers may offer an emulation of transactions, but sometimes with significant overhead, in which case the user must explicitly allow for such an emulation by setting bForce to TRUE.

Drivers that offer emulated transactions should advertise the ODsCEmulatedTransactions capability and not ODsCTransactions. bForce — can be set to TRUE if an emulation, possibly slow, of a transaction mechanism is acceptable. For datasources which support transactions, RollbackTransaction will roll back a datasource to its state before the start of the current transaction. papszOptions — Driver specific options determining how attributes should be retrieved.

Pass nullptr for default behavior. Only a few drivers will support this operation, and some of them might only support it only for some types of field domains. At the time of writing GDAL 3. A dataset having at least some support for this operation should report the ODsCAddFieldDomain dataset capability. Anticipated failures will not be emitted through the CPLError infrastructure, but will be reported in the ppszFailureReason output parameter.

hFieldDomain — The domain definition. ppszFailureReason — Output parameter. May be NULL. A dataset having at least some support for this operation should report the ODsCDeleteFieldDomain dataset capability. A dataset having at least some support for this operation should report the ODsCUpdateFieldDomain dataset capability. Anticipated failures will not be emitted through the CPLError infrastructure, but will be reported in the failureReason output parameter.

papszOptions — Driver specific options determining how relationships should be retrieved. Only a few drivers will support this operation, and some of them might only support it only for some types of relationships. A dataset having at least some support for this operation should report the GDsCAddRelationship dataset capability. Some dataset formats require particular naming conventions and field structures for the mapping table, and delegating the construction of the mapping table to the driver will avoid these pitfalls.

hRelationship — The relationship definition. A dataset having at least some support for this operation should report the GDsCDeleteRelationship dataset capability. A dataset having at least some support for this operation should report the GDsCUpdateRelationship dataset capability. Use GDALRasterIOEx if 64 bit spacings or extra arguments resampling resolution, progress callback, etc.

Depending on drivers, changing the no data value may or may not have an effect on the pixel values of a raster that has just been created. It is thus advised to explicitly called Fill if the intent is to initialize the raster to the nodata value. In any case, changing an existing no data value, when one already exists and the dataset exists or has been initialized, has no effect on the pixel whose value matched the previous nodata value.

In ay case, changing an existing no data value, when one already exists and the dataset exists or has been initialized, has no effect on the pixel whose value matched the previous nodata value.

Return a view of this raster band as a 2D multidimensional GDALMDArray. The band must be linked to a GDALDataset. If this dataset is not already marked as shared, it will be, so that the returned array holds a reference to it. If the dataset has a geotransform attached, the X and Y dimensions of the returned array will have an associated indexing variable. Derived bands are stored with only the name of the pixel function that it will apply, and if a pixel function matching the name is not found the IRasterIO call will do nothing.

pfnNewFunction — Pixel function associated with name. An existing pixel function registered with the same name will be replaced with the new one. Mask band must be understood in the broad term: it can be a per-dataset mask band, an alpha band, or an implicit mask band. Returns whether a sub-window of the raster contains only data, only empty blocks or a mix of both. Empty blocks are blocks that are generally not physically present in the file, and when read through GDAL, contain only pixels whose value is the nodata value when it is set, or whose value is 0 when the nodata value is not set.

The query is done in an efficient way without reading the actual pixel values. The nMaskFlagStop should be generally set to 0. As soon as one missing block is encountered, the function will exit, so that you can potentially refine the requested area to find which particular region s have missing blocks.

nXOff — The pixel offset to the top left corner of the region of the band to be queried. nYOff — The line offset to the top left corner of the region of the band to be queried. As soon as the computation of the coverage matches the mask, the computation will be stopped.

pdfDataPct — Optional output parameter whose pointed value will be set to the approximate percentage in [0,] of pixels in the queried sub-window that have valid values. The implementation might not always be able to compute it, in which case it will be set to a negative value.

Provide an opportunity for an asynchronous IO request to update the image buffer and return an indication of the area of the buffer that has been updated. The dfTimeout parameter can be used to wait for additional data to become available. The timeout does not limit the amount of time this method may spend actually processing available data.

The following return status are possible. The request should be ended and the buffer used. dfTimeout — the number of seconds to wait for additional updates. Use -1 to wait indefinitely, or zero to not wait at all if there is no data available. pnBufXOff — location to return the X offset of the area of the request buffer that has been updated. pnBufYOff — location to return the Y offset of the area of the request buffer that has been updated.

pnBufXSize — location to return the X size of the area of the request buffer that has been updated. pnBufYSize — location to return the Y size of the area of the request buffer that has been updated. Locks the image buffer passed into GDALDataset::BeginAsyncReader. This is useful to ensure the image buffer is not being modified while it is being used by the application. UnlockBuffer should be used to release this lock when it is no longer needed. dfTimeout — the time in seconds to wait attempting to lock the buffer.

Default is This function is intended to provide a variety of generic commandline options for all GDAL commandline utilities. It takes care of the following commandline options:. The typical usage looks something like the following. updated nArgc argument count. Return of 0 requests terminate without error, return of -1 requests exit with error code. No assumption is made that the words being swapped are word aligned in memory. h to determine if the current platform is big endian or little endian.

nWordSkip — the byte offset from the start of one word to the start of the next. For packed buffers this is the same as nWordSize. This function is used to copy pixel word values from one memory buffer to another, with support for conversion between data types, and differing step factors.

The data type conversion is done using the normal GDAL rules. Values assigned to a lower range integer type are clipped. Assignment from floating point to integer uses default C type casting semantics. Assignment from non-complex to complex will result in the imaginary part being set to zero on output. Assignment from complex to non-complex will result in the complex portion being lost and the real component being preserved not magnitude! No assumptions are made about the source or destination words occurring on word boundaries.

It is assumed that all values are in native machine byte order. When adding a new data type to GDAL, you must do the following to support it properly within the GDALCopyWords function: Add the data type to the switch on eSrcType in GDALCopyWords. This should invoke the appropriate GDALCopyWordsFromT wrapper.

Add the data type to the switch on eDstType in GDALCopyWordsFromT. This should call the appropriate GDALCopyWordsT template. If appropriate, overload the appropriate CopyWord template in the above namespace. nDstPixelStride — Destination pixel stride i. distance between 2 words , in bytes.

A function for moving sets of partial bytes around. Loosely speaking this is a bitwise analog to GDALCopyWords. The nSrcStep and nDstStep are the number of bits from the start of one word to the next same as nBitCount if they are packed. The nSrcOffset and nDstOffset are the offset into the source and destination buffers to start at, also measured in bits.

All bit offsets are assumed to start from the high order bit in a byte i. most significant bit first. Currently this function is not very optimized, but it may be improved for some common cases in the future as needed. nSrcOffset — the offset in bits in pabySrcData to the start of the first word to copy.

nSrcStep — the offset in bits from the start one source word to the start of the next. nDstOffset — the offset in bits in pabyDstData to the start of the first word to copy over. The implementation is optimized for a few cases, like de-interleaving of 3 or 4-components Byte buffers. The world file contains an affine transformation with the parameters in a different order than in a geotransform array.

padfGeoTransform — the six double array into which the geotransformation should be placed. This function reads an ESRI style world file, and formats a geotransform from its contents. It does the same as GDALLoadWorldFile function, but it will form the filename for the worldfile from the filename of the raster file referred and the suggested extension.

If no extension is provided, the code will internally try the unix style and windows style world file extensions eg. tif these would be. tfw and. pszExtension — the extension to use i. padfGeoTransform — the six double array from which the geotransformation should be read. Before GDAL 1. So the result should not been freed by the caller. The purpose of this method is to ensure that calling code will run with the GDAL version it is compiled for. It is primarily intended for external plugins.

pszCallingComponentName — If not NULL, in case of version mismatch, the method will issue a failure mentioning the name of the calling component. Get the names of the mapping table fields which correspond to the participating fields from the left table in the relationship. Get the names of the mapping table fields which correspond to the participating fields from the right table in the relationship.

Sets the names of the mapping table fields which correspond to the participating fields from the left table in the relationship. Sets the names of the mapping table fields which correspond to the participating fields from the right table in the relationship.

The forward and backward path labels are free-form, user-friendly strings which can be used to generate descriptions of the relationship between features from the right and left tables. This a free-form string representing the type of related features, where the exact interpretation is format dependent. For instance, table types from GeoPackage relationships will directly reflect the categories from the GeoPackage related tables extension i.

This function sets the maximum amount of memory that GDAL is permitted to use for GDALRasterBlock caching. The unit of the value is bytes. The maximum value is 2GB, due to the use of a signed 32 bit integer. Use GDALSetCacheMax64 to be able to set a higher value. Otherwise it is expected to be a value in MB.

This function cannot return a value higher than 2 GB. Use GDALGetCacheMax64 to get a non-truncated value. Note: On 32 bit platforms, the maximum amount of memory that can be addressed by a process might be 2 GB or 3 GB, depending on the operating system capabilities. This function will not make any attempt to check the consistency of the passed value with the effective capabilities of the OS.

This function will search the first unlocked raster block and will flush it to release the associated memory.

TRUE if one block was flushed, FALSE if there are no cached blocks or if they are currently locked. This method allows creating a virtual memory object for a region of one or more GDALRasterBands from this dataset.

The pointer to access the virtual memory object is obtained with CPLVirtualMemGetAddr. It remains valid until CPLVirtualMemFree is called.

CPLVirtualMemFree must be called before the dataset object is destroyed. Note that the mechanism used to transparently fill memory pages when they are accessed is the same but in a controlled way than what occurs when a memory error occurs in a program. Debugging software will generally interrupt program execution when that happens. If needed, CPLVirtualMemPin can be used to avoid that by ensuring memory pages are allocated before being accessed. The size of the region that can be mapped as a virtual memory object depends on hardware and operating system limitations.

On Linux AMD64 platforms, the maximum value is TB. On Linux x86 platforms, the maximum value is 2 GB. Data type translation is automatically done if the data type eBufType of the buffer is different than that of the GDALRasterBand. if the size of the region being accessed nXSize x nYSize is different from the buffer size nBufXSize x nBufYSize.

The nPixelSpace, nLineSpace and nBandSpace parameters allow reading into or writing from various organization of buffers. Arbitrary values for the spacing parameters are not supported. eBufType — the type of the pixel values in the data buffer. nPixelSpace — The byte offset from the start of one pixel value in the buffer to the start of the next pixel value within a scanline. nLineSpace — The byte offset from the start of one scanline in the buffer to the start of the next.

nCacheSize — size in bytes of the maximum memory that will be really allocated must ideally fit into RAM. nPageSizeHint — hint for the page size. Must be a multiple of the system page size, returned by CPLGetPageSize. Minimum value is generally Might be set to 0 to let the function determine a default page size.

bSingleThreadUsage — set to TRUE if there will be no concurrent threads that will access the virtual memory mapping. This can optimize performance a bit. If set to FALSE, CPLVirtualMemDeclareThread must be called. This method allows creating a virtual memory object for a region of a GDALRasterBand. CPLVirtualMemFree must be called before the raster band object is destroyed. The nPixelSpace and nLineSpace parameters allow reading into or writing from various organization of buffers.

Contrary to GDALDatasetGetVirtualMem , pixels will be organized by tiles instead of scanlines. This method allows creating a virtual memory object for a region of one GDALRasterBand. Note that no reference will be taken on the passed bands. Consequently, they or their dataset to which they belong to must be kept open until this virtual pansharpened dataset is closed.

The returned dataset will have no associated filename for itself. If you want to write the virtual dataset description to a file, use the GDALSetDescription function or SetDescription method on the dataset to assign a filename before it is closed. The spectral bands in the XML will be assigned the successive values of the pahInputSpectralBands array.

Must not be NULL. nInputSpectralBands — Number of input spectral bands. Must be greater than zero. NULL on failure, or a new virtual dataset handle on success to be closed with GDALClose. papszOptions — NULL terminated list of options, or NULL. nTotalSize — Total size of the type in bytes. Should be large enough to store all components. Note: when applied on a object coming from a driver, this does not destroy the object in the file, database, etc….

The returned array and its content must be freed with GDALExtendedDataTypeFreeComponents. If only the array itself needs to be freed, CPLFree should be called and GDALExtendedDataTypeRelease on individual array members. This is the same as the C function GDALExtendedDataType::CanConvertTo.

Create a new GDALEDTComponent. Return the root GDALGroup of this dataset. See GDALGroup::ResolveMDArray for description of the behavior. Note that the vector layer is owned by its parent GDALDatasetH, and thus the returned handled if only valid while the parent GDALDatasetH is kept opened.

The returned array must be freed with GDALReleaseDimensions. If only the array itself needs to be freed, CPLFree should be called and GDALDimensionRelease on individual array members. papszOptions — Driver specific options determining how dimensions should be retrieved.

The returned array must be freed with GDALReleaseAttributes. If only the array itself needs to be freed, CPLFree should be called and GDALAttributeRelease on individual array members. The return value should not be freed and is valid until GDALGroup is released or this function called again. Release the GDAL in-memory object associated with a GDALMDArray. The value returned might be nullptr in case of no nodata value. When a nodata value is registered, a non-nullptr will be returned whose size in bytes is GetDataType.

pbHasNoDataValue — Pointer to a output boolean that will be set to true if a nodata value exists and can be converted to double. protected void onCreate Bundle savedInstanceState {.

Macro to initialize an instance of GDALRasterIOExtraArg structure. Typically set for non-file based drivers. Generally used with open options. Since GDAL 2. This capability reflects that a raster driver supports child layers, such as NetCDF or multi-table raster Geopackages. Capability set by a driver that implements the CreateCopy API, but with multidimensional raster as input and output. List of space separated flags support by the OGRLayer::AlterFieldDefn API.

For example, altering the field type may be restricted by the current type of the field, etc. non-spatial vector drivers e. spreadsheet format drivers do not support geometries, and accordingly will have this capability present.

These flags indicate that the driver does not differentiate between single-part and multi-part linestring and polygon geometries when writing features respectively. This capability is only set for drivers of formats which have a native concept of multiple vector layers such as GeoPackage. List of space separated flags indicating the features of relationships are supported by the driver.

If not present then only a single field name can be used. List of space separated flags support by the OGRLayer::AlterGeomFieldDefn API. For example, altering the geometry type may be restricted by the type of the geometries in the field, or changing the nullable state to non-nullable is not possible if null geometries are present, etc. Other dialect values may also be present for some drivers for some of them, the query string to use might not even by SQL but a dedicated query language.

For further details on their interpretation, see the documentation for the respective driver. Value for GDALDimension::GetType specifying the X axis of a horizontal CRS. Value for GDALDimension::GetType specifying the Y axis of a horizontal CRS.

Value for GDALDimension::GetType specifying a vertical axis. Value for GDALDimension::GetType specifying a temporal axis.

Value for GDALDimension::GetType specifying a parametric axis. Used by GDALOpenEx. Since GDAL 3. Let GDAL decide if a array-based or hashset-based storage strategy for cached blocks must be used. Flag returned by GDALGetMaskFlags to indicate that all pixels are valid. Flag returned by GDALGetMaskFlags to indicate that the mask band is valid for all bands. Flag returned by GDALGetMaskFlags to indicate that the mask band is an alpha band.

Flag returned by GDALGetMaskFlags to indicate that the mask band is computed from nodata values. Flag returned by GDALGetDataCoverageStatus when the driver does not implement GetDataCoverageStatus.

Flag returned by GDALGetDataCoverageStatus when there is potentially data in the queried window. Flag returned by GDALGetDataCoverageStatus when there is nodata in the queried window. This is typically identified by the concept of missing block in formats that supports it.

Helper macro for GDALCheckVersion. Grayscale in GDALColorEntry. Enumeration giving the class of a GDALExtendedDataType. Enumeration giving the subtype of a GDALExtendedDataType. Tile Interleaved by Pixel: tile 0,0 with internal band interleaved by pixel organization, tile 1, 0 , ….

Band Interleaved by Tile : tile 0,0 of first band, tile 0,0 of second band, … tile 1,0 of first band, tile 1,0 of second band, …. Use GDALGetDataTypeSizeBytes for bytes. In contrast, GDALGetDataTypeSize returns the size in bits. Returns a symbolic name for the data type.

The returned strings are static strings and should not be modified or freed by the application. These strings are useful for reporting datatypes in debug statements, errors and other user output.

Returns a data type corresponding to the given symbolic name. This function is opposite to the GDALGetDataTypeName. pbClamped — pointer to a integer boolean to indicate if clamping has been made, or NULL.

pbRounded — pointer to a integer boolean to indicate if rounding has been made, or NULL. If the input data type is complex this function returns the base type i. the data type of the real and imaginary parts non-complex.

If the input data type is already non-complex, then it is returned unchanged. Returns a symbolic name for the AsyncStatus data type. This function is opposite to the GDALGetAsyncStatusTypeName. Returns a symbolic name for the color interpretation. Returns a color interpretation corresponding to the given symbolic name. This function is opposite to the GDALGetColorInterpretationName.

Returns a symbolic name for the palette interpretation. This function will drive any of the following that are configured into GDAL. See raster list and vector full list. This function will try to identify the driver that can open the passed file name by invoking the Identify method of each registered GDALDriver in turn.

The first driver that successful identifies the file name will be returned. If all drivers fail then NULL is returned.

In order to reduce the need for such searches touch the operating system file system machinery, it is possible to give an optional list of files. This is the list of all files at the same level in the file system as the target file, including the target file. The filenames will not include any path components, are essentially just the output of VSIReadDir on the parent directory.

If the target object does not have filesystem semantics then the file list should be NULL. pszFilename — the name of the file to access. In the case of exotic drivers this may not refer to a physical file, but instead contain information for the driver on how to access a dataset.

papszFileList — an array of strings, whose last element is the NULL pointer. These strings are filenames that are auxiliary to the main filename. The passed value may be NULL. A GDALDriverH handle or NULL on failure. If none of the value is specified, both kinds are implied. papszAllowedDrivers — NULL to consider all candidate drivers, or a NULL terminated list of strings with the driver short names that must be considered.

Open a raster file as a GDALDataset. This function will try to open the passed file, or virtual dataset name by invoking the Open method of each registered GDALDriver in turn. The first successful open will result in a returned dataset. If all drivers fail then NULL is returned and an error is issued. The returned dataset should only be accessed by one thread at a time.

Open a raster or vector file as a GDALDataset. In order to reduce the need for searches through the operating system file system machinery, it is possible to give an optional list of files with the papszSiblingFiles parameter.

The filenames must not include any path components, are essentially just the output of VSIReadDir on the parent directory.

If set, a failed attempt to open the file will lead to an error message to be reported. papszOpenOptions — NULL, or a NULL terminated list of strings with open options passed to candidate drivers. The level index starts at 0. Open options are validated by default, and a warning is emitted in case the option is not recognized.

In some scenarios, it might be not desirable e. Alternatively, since GDAL 2.
