no luck. :-(
I have tryed changing utm "zone=29" on the map and "zone=30" on the layer
without success. Also, i changed IMAGETYPE from PNG to PNG24, and i have
discovered that transparency information is being lost, as i am getting now
an ugly green background.
Also there is an speed penalty because of the extra reprojection time.
I have tryed renaming ".tif" to ".png", but it didn't work. He.
I allways get an Internal Server Error if i try to use tiff raster layers.
I am now using tiff2png to batch-convert all my tiffs to PNG, and it works
Thanks for your help.
