A couple of responses followed this posting. Here's my two bits:
Bill Thompson suggested using TVRD to read the image off the Wave-generated
X-Window, and then plotting the image to a Postscript file. Unfortunately,
this closes the X server connection, and any other Wave windows with it.
Rolf Diehl suggested using xwd, xpr and lp. This is a more general
approach, and has the advantage of being able to dump non-Wave windows as
well. Unfortunately, xpr is limited to at best a 4x4 dither representation
of color to a monochrome printer. It won't deal with color PS printers.
Also, I have been unable to render large windows, either by spreading them
across printed pages (-split n), or by scaling them (-scale n).
I've been looking at other alternatives, too. I've considered a variant of
Bill's method which would use DC_WRITE_TIFF instead of switching to
postscript. Then the tiff-printer (perhaps from Sam Loeffer's stuff?) could
be spawned. Again, this would require some contortions to print a non-Wave
window.
I guess the ideal solution would be to find a xwd-format to
PostScript-format converter. This would be similar to Rolf's solution, but
would avoid the weaknesses of xpr.
Does anyone know of such a utility?
