-
eggshell.eo.gdal_merge.names_to_fileinfos(names)[source]¶ Translate a list of GDAL filenames, into file_info objects.
names – list of valid GDAL dataset names.
Returns a list of file_info objects. There may be less file_info objects than names if some of the names could not be opened as GDAL files.
-
class
eggshell.eo.gdal_merge.file_info[source]¶ A class holding information about a GDAL file.
-
init_from_name(self, filename)[source]¶ Initialize file_info from filename
filename – Name of file to read.
Returns 1 on success or 0 if the file can’t be opened.
-
copy_into(self, t_fh, s_band=1, t_band=1, nodata_arg=None)[source]¶ Copy this files image into target file.
This method will compute the overlap area of the file_info objects file, and the target gdal.Dataset object, and copy the image data for the common window area. It is assumed that the files are in a compatible projection … no checking or warping is done. However, if the destination file is a different resolution, or different image pixel type, the appropriate resampling and conversions will be done (using normal GDAL promotion/demotion rules).
t_fh – gdal.Dataset object for the file into which some or all of this file may be copied.
Returns 1 on success (or if nothing needs to be copied), and zero one failure.
