[Qgis-developer] printing issues

Hi all,
Thanks once again for your testing.

This is a known problem for cache mode, since the cache is created at a
variable resolution and then variably scaled.  In render mode, the line
widths appear to correspond.  I'll try to look into it more when I get a
chance (unfortunately, that may be a few weeks).

I changed the line for the polygon outline to be a "cosmetic pen" (1px wide,
regardless of scale) when the line widths were getting out of hand.  Since
that should be fixed now, I can probably put the original line widths back.

I haven't done much testing with vector labels, so I'm not too surprised
some bugs still lurk there.  If you could send me some simple projects which
reproduce the problem, that would be great help.

Unfortunately, I don't think we can fix this for 0.9.  It will require some
significant changes to the symbology and rendering, which has the potential
to break things.

moreover, point size is much larger (1.4x? 2x?) in the legend than in

The ugly font bug strikes again!  What operating system and Qt version are
you using?  I have exactly the same problem, and I don't think there's much
we can do.  (I'm running Ubuntu with Qt 4.2/4.3)

I'm pretty sure Qt provides the default font, so we'd have to manually
override this.  I'll see if we can do this in a simple, cross-platform way.
The font size is calculated based off of the map scale, and often is less
than 6.  Perhaps some code to limit the default to a minimum of 8 would be
helpful.

I'm not going to have much time to work on QGIS in the next few weeks, but
I'll try to fix what I can for 0.9.
