Re: gEDA-user: gschem printing problems

Hi,

Odd, Ghostscript shows your file correctly.

I can guess that this is a side effect of the way that the current 
postscript output works.  There are likely  some potntial bugs in the 
way that the scaling and rotation are applied to the output, mainly from 
the page size getting calculated in several places, and lots of trickery 
to do with passing back and forth scaling factors.  I am currently 
working on fixing this and plan to upload the changes to CVS in a day or 
two.  I have almost completely rewritten the printing back end for 
gschem.  The scaling and rotation are the last things for me to patch. 
You will also notice approximately 50% reduction in the postscript file 
size due to lower verbosity in the output.

The fix should be there in a few days.  I wil properly rotate and scale 
the drawing so that it appears `portrait' on the page, along with 
appropriately set bounding boxes.  What you see is probably because 
ps2pdf ignores the bounding box and calculates it's own, then rotates 
and scales the file to fit on a standard sheet.  I know that the output 
code also injects some `setpagedevice' commands under certain 
circumstances, and these may be confusing your printer.  The PDF 
translator may remove these and thus make your printout appear correctly.
