I have recently built the R3 release of X11 and am having extensive problems with getting Xwd dump files to print using either Xpr or pbm and I was wondering if there was a known solution to this problem. My impression at this point is that the problem may be with Xwd and machine dependencies with the qvss server, though this is only a wild guess on my part, as both parts of Xpr and pbm fail to properly read the dump files. Suggestions, solutions would be most appreciated. For reference I'm running on a diskless Vaxstation 2000 with a monochrome VR260 display running Ultrix 2.2. --Richard Auletta rauletta@sitevax.gmu.edu ...uunet!pyrdc!gmu90x!rauletta

I wouldn't think that the problem is any machine dependency with the qvss server, but a more general bug. Any help out there? I have a Vaxstation II running Ultrix 2.3 (monochrome Xqvss). It also gives the same error message on our 4-plane color vaxstation 2000 running Ultrix 3.0 (Xqdss server). Brian Smith bvsmith@lbl.gov

I don't know if this is related, but when I do a `xwd' on a color Sun-3/260C (using the `-xy' option as required for color), the dump file seems to be OK (a subsequent `xwud' works just fine), but when fed to a resulting `xpr -density 300 -device ps' the bitmap in the PostScript output is an all-black window (i.e., all 0's in the bitmap segment of the PostScript). This happens even when the window which is dumped is black-on-white. One thing that is confusing in the documentation is that the `xwd' man page says that one needs to use XYPixmap dump format: -xy This option applies to color displays only. It selects `XY' format dumping instead of the default `Z' format. Yet, the `xpr' man page seems to contradict this: Multiplane images must be recorded by `xwd' in `ZPixmap' format. Single plane (monochrome) images may be in either `XYPixmap' or `ZPixmap' format. (Further clouding the issue is that the above comment comes at the end of a section about HP printers.) Can someone clarify this? I thought that `xpr' would convert any input color to an appropriate white/black value ... -- Greg Earle earle@Sun.COM Sun Microsystems earle@mahendo.JPL.NASA.GOV JPL on-site Software Support poseur!earle@elroy.JPL.NASA.GOV ...!{cit-vax,ames}!elroy!poseur!earle ...!sun!{poseur!}earle

`xpr -density 300 -device ps' the bitmap in the PostScript output is an
all-black window (i.e., all 0's in the bitmap segment of the PostScript).
Right, because xpr is stupidly just choosing a fixed bit plane (usually the
wrong one) to output.
One thing that is confusing in the documentation is that the `xwd' man page
says that one needs to use XYPixmap dump format:
Yet, the `xpr' man page seems to contradict this:
XY and Z are equivalent for 1-bit images, and xpr will eat either. For
N-bit images, the R3 xpr will only eat XY format.
I thought that `xpr' would convert any input
color to an appropriate white/black value ...
It will in R4 (our current internal version does).gmk@texhrc.UUCP (Gail Kahle) (03/31/89)
This is a test.
