Hi Pierre,

Does gdal2wktraster.py have any limitation on the maximum number of
columnsxrows ?

in my case, my raster is  107759 x 168633...

gdal works well:

sebas at SeansPC:~/rasters$ gdal_translate -of PNG raster/ test.png
Input file size is 107759, 168633
0...10...20...30...40...50...60...70...80...90...100 - done.
