Sample file that shows the problem. Viewing with antialias makes some text go
away unless you also add "/setoverprint {pop} def".

Test with antialiasing enabled where a block of text is missing.
I suspect this is similar to the problem where anti-alias malfunctions with the pdf14 compositor device in the chain. This problem can be reproduced in old versions of Ghostscript with the following command line. ~/ghostscript-9.00/bin/gs -sDEVICE=x11alpha -dEPSCrop setoverprint.eps It was fixed in ghostscript-9.04 in 2011. Please close this bug report as fixed. |
