Can I use GDALCreate to create (and later write to) PNG images?
If so, is "PNG" the correct string for GDALGetDriverByName?
Otherwise, can somebody please let me know why the code below returns NULL from
GDALCreate (assigned to dstDS)?
Advice much appreciated, as always.
Thanks,
Nik.
GDALDriverH hDriver = GDALGetDriverByName("PNG");
char **papszOptions = NULL;
papszOptions = CSLSetNameValue( papszOptions, "WORLDFILE", "NO" );
papszOptions = CSLSetNameValue( papszOptions, "ZLEVEL", "9" );
GDALDatasetH dstDS = GDALCreate( hDriver, "/var/tmp/image.png", 256,
256, 4, GDT_Float32, papszOptions );
