(this worked fine with the earlier patches I used for 1.1.6 from Kevin Cazabon) The output of the pil setup summary: -------------------------------------------------------------------- PIL 1.1.7a0 SETUP SUMMARY -------------------------------------------------------------------- version 1.1.7a0 platform darwin 2.5.1 (r251:54863, Jan 13 2009, 10:26:13) [GCC 4.0.1 (Apple Inc. build 5465)] -------------------------------------------------------------------- --- TKINTER support available --- JPEG support available --- ZLIB (PNG/ZIP) support available --- FREETYPE2 support available --- LITTLECMS support available -------------------------------------------------------------------- I have a couple of photos with which i have the problems. I could mail you these directly if you want.
