Hi All, I have a problem with gdal_retile.py 1.9.0. I used it to generate pyramid for a set of GeoTIFFs. They contain RGB ortophoto. Where there is no data, the image appears white in an image viewer. Where there was no tile, but the script needed to put some nodata color, it choosed black. As a consequence, the next level started from this one uses black as a color, and at the border of black nodata and real photographic content, the black nodata gets contanimated, so it is not totally black anymore. The higher the pyramid level, the thicker the contanimation. It cannot be observed by eye, only if an other layer is put behind this ortophoto layer in Geoserver - the nearly black pixels cover a strip from the layer underneath. (total black nodata is filtered by Geoserver setting, so it is transparent).
Do you know any solution apart of writing a custom filter for nearly black pixels using GDAL C API? thank you in advance.
