Pure python implementation of reading a chunk of a GDAL file into a numpy array. Used by the gdal.Band.ReadAsArray method.

osgeo.gdal_array.BandWriteArray(band, array, xoff=0, yoff=0, resample_alg=0, callback=None, callback_data=None)

Pure python implementation of writing a chunk of a GDAL file from a numpy array. Used by the gdal.Band.WriteArray method.

osgeo.gdal_array.CopyDatasetInfo(src, dst, xoff=0, yoff=0)

Copy georeferencing information and metadata from one dataset to another. src: input dataset dst: output dataset - It can be a ROI - xoff, yoff: dst's offset with respect to src in pixel/line.

Notes: Destination dataset must have update access. Certain formats

do not support creation of geotransforms and/or gcps.

Pure python implementation of reading a chunk of a GDAL file into a numpy array. Used by the gdal.Dataset.ReadAsArray method.

osgeo.gdal_array.DatasetWriteArray(ds, array, xoff=0, yoff=0, band_list=None, interleave='band', resample_alg=0, callback=None, callback_data=None)

Pure python implementation of writing a chunk of a GDAL file from a numpy array. Used by the gdal.Dataset.WriteArray method.

osgeo.gdal_array.DontUseExceptions()

Disable exceptions in all GDAL related modules (osgeo.gdal, osgeo.ogr, osgeo.osr, osgeo.gnm). Note: prior to GDAL 3.7, this only affected the calling module

class osgeo.gdal_array.ExceptionMgr(useExceptions=True)

Bases: object

Context manager to manage Python Exception state for GDAL/OGR/OSR/GNM.

Separate exception state is maintained for each module (gdal, ogr, etc), and this class appears independently in all of them. This is built in top of calls to the older UseExceptions()/DontUseExceptions() functions.

Example:

>>> print(gdal.GetUseExceptions())
0
>>> with gdal.ExceptionMgr():
...     # Exceptions are now in use
...     print(gdal.GetUseExceptions())
1
>>>
>>> # Exception state has now been restored
>>> print(gdal.GetUseExceptions())
0
