I'd be speaking out of school. It appears to me that netpbm's pgm supports 16-bit alpha channels http://netpbm.sourceforge.net/doc/pgm.html and it looks to me like Photoshop supports them as well (in 16bpp file), and a cursory reading of the PDF 1.7 Reference suggests no limitation to 8 bits. But I could definitely be misreading this. --jh...@mit.edu John Hawkinson _______________________________________________ Qgis-developer mailing list Qgis-developer@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer
