Description Unknown 2002-11-09 01:24:25 UTC 
When printing a drawing which contains Bezier curves, these are always 
converted to paths of straight lines although Bezier curves exist in the 
Postscript language as well.
The installed printing module (Xprint or PSprint) is unknown.
I was able to reproduce this handling of Bezier under OpenOffice 1.0.0 and 
StarOffice 6.0 with arbitrary drawings containing Bezier curves.

added an SDW file and its postscript output on my system to 
illustrate the issue

of course the ending of the first file should be sdd ;)

I think that should be already fixed in the 643 C Windows version.
Could you test that. Support for Unix/PsPrint is on it's way.
Comment 6 christof.pintaske 2003-06-19 17:04:43 UTC 
cp->aw: vcl supports bezier since a couple of time, so we are done. If
you are going to do anything on this please keep it. Otherwise close
or give back to me.

AW->THB: Something for 'Q'?

This topic is rather manifold. First of all, Christof is right that generally 
speaking, we pipe through beziers to PostScript now. Was planned to do that also for 
the draw shapes, but it was considered too risky because everybody and his grandma 
relied on the fact that XOutDev polygons do not contain beziers anymore. This can 
surely be reconsidered for OOo 2.0. Objects that use VCL OutDev natively, such as EMF 
files, have correct PostScript output even today.
Remains the case of thick lines, 
especially with dashing. Sadly, these cannot be mapped directly to PostScript, but 
have to be subdivided into a filled polygon. And having this polygon contain curves 
that correctly approximate the true shape isn't exactly a no-brainer. But that's also 
planned for 2.0.

To conclude: accepted for 2.0, let's see how far we get this.

"According to the OpenOffice.org roadmap
(http://tools.openoffice.org/releases) this issue was retargeted to
OOo Later."
