Any simple way to see this issue myself? Here you go for two test pdf files. I use the gradients in drawing the arrow heads. I use OSX10.8.4 Preview In the first file it leaves the blank.

Well these are the binaries compiled by the late Travis Griggs and included in Cincom Visualworks, in fact the method libraryVersion gives 1.10.2 I only use: libcairo.2.dylib, libpixman-1.0.dylib and libpng15.0.dylib. > >> Is this a known issue ?? > [...] > > Not yet, but thanks to you it is known now, I guess. > > > Uli > -- > "For saving the Earth.. and eating cheesecake!" _______________________________________________ vwnc mailing list [email protected] http://lists.cs.uiuc.edu/mailman/listinfo/vwnc
