Using Ghostscript at the commandline, this file gets antialiased properly. This sounds like a bug in GSview 4.5. Please report it in the appropriate place. My copy of GSview 4.5 on Linux also displays the correct behavior for this file. Using ghostscript alone from the command line on Windows, this file is anti- aliased with GS 7.07, but is NOT anti-aliased with 8.11. I'll analyze it. Meanwhile please put the test document as an attachment. Click "Create a New Attachment" abobe to do that. In future please don't put documents into a followup. This way causes distortions to binaries and line breaks. Created attachment 343 [details]
Test postscript file test.ps
This is the file test.ps as an attachment, as requested.
Update of my original bug report: My other PCs are actually running GS 8.0, not 8.11 (as I somehow had assumed, without actually checking). With 8.0, everything is fine, but with 8.11, they show the same anti-aliasing problems as reported. The problem, therefore, seems to stem from the changes made between 8.00 and 8.11. |
Installing Ghostscript 8.11 and GSview 4.5 under Windows XP Pro SP1 on a new Sony Vaio V505DC2P laptop, I noticed that anti-aliasing display settings in GSview 4.5 (1, 2, or 4 bits) have no effect whatsoever (i.e., the screen output always corresponds to that of the 1-bit setting). Replacing GS 8.11 by 7.04 cures the problem. I include a brief postscript test file that shows the problem. On the Sony notebook, the problem is always reproducible, i.e., GS 8.11: bad; GS 7.04: good. I haven't done any tests with other versions of Ghostscript. Note, however, that of the four PCs I have, the problem is specific to the Sony notebook; it does not occur on any of the other three (one of them is also Sony notebook -- an older Vaio Z505HS model). Regards, --Helmut Haberzettl PS: I don't have clue which component is responsible for this behavior. The choice "MS Windows Display Driver" is just a wild guess.
