Description Netterfield 2005-12-02 02:10:37 UTC

Version:           1.2.0_devel (using KDE 3.4.1, Gentoo)
Compiler:          gcc version 3.3.5-20050130 (Gentoo 3.3.5.20050130-r1, ssp-3.3.5.20050130-1, pie-8.7.7.1)
OS:                Linux (i686) release 2.6.9-gentoo-r6

Printing or exporting to pdf has reverted to bitmaps rather than vector graphics again.

How to see:
Make a plot in kst
export to pdf
open with kpdf
Zoom a long way in: see bitmap jaggies, not nice straight lines.

You can also just print it and see the same ugliness.

I don't recall we had ever done anything special with pdf. There was a fix/hack that we applied for EPS; is that what you were thinking of?

   The only thing that is a bitmap for me is labels.  Everything else is 
definitely vector based.  I'm not sure we can easily address the label issue 
and still preserve the label features we have.

Comment 3 Netterfield 2005-12-02 18:39:45 UTC

Vector labels in printing is a non-negotiable requirement.

Comment 4 Matthew Truch 2005-12-02 22:14:38 UTC

I've just looked more carefully at the plots I printed to 'confirm' that black and white printing works ok, and noticed that yes, they are not at the right resolution.  After comparing to plots I printed with kst circa ~2 months ago (I didn't print anything in the meantime), it looks like printouts are printed at screen resolution instead of finer (printer) resolution.

Comment 5 George Staikos 2005-12-02 22:33:57 UTC

  Labels, or other?  The labels aren't at a low resolution anyway - they're 
being rasterized instead of output as PS/PDF operations.

Comment 6 Matthew Truch 2005-12-02 22:52:15 UTC

Labels *and* others (curves in particular).

Comment 7 George Staikos 2005-12-02 23:00:49 UTC

  How are you determining this?  I'm quite certain that we're using vector 
postscript operations which makes resolution rather irrelevant.

By comparing physical printouts on the same printer of (almost)
identical plots of two different versions of kst, one from 2 months ago,
and trunk.  I even tried another printer to be sure.

  Hmm ok, we'll have to investigate.  There are a lot of variables in there 
still...

BUG: 117481

when printing, 2D plots are informed that the paint type is 
P_PRINT...
