Package: libqt3c102-mt
Version: 3:3.2.3-3
Severity: normal
QT (I'm assuming it's a QT thing as the option is saved in ~/.qt/qtrc)
does a very poor job at generating embedded glyphs in postscript
files. (I've tried both truetype and type 1 fonts). The visual
result is that character spacing is messed up (individual letters butt
up against each other or look like they have spaces between them).
This affects all KDE apps that print, as they output postscript and
then let the printing system convert it (via gs) to the appropriate
printer format.
To see this:
1) Turn on font embedding: [the default]
From the Printing Manager's tool bar pick Configure Manager, Fonts,
and then click on Embed fonts in Postscript data (this sets
embedFonts=true in ~/.qt/qtrc under the [General] section).
2) Print a postscript file:
Open a reasonably sized document in KWord (or email in KMail, etc)
and print to a postscript file (call is 1.ps).
3) Turn off font embedding:
From the Printing Manager's tool bar pick Configure Manager, Fonts
and then click off Embed fonts in Postscript data (this sets
embedFonts=false in ~/.qt/qtrc under the [General] section).
4) Print a postscript file:
Open the same document in KWord (or email in KMail, etc) and print
to a postscript file (call it 2.ps).
5) Look at the differnce:
Print 1.ps and 2.ps and look at the difference (you can also just
view them side by side in gv with a magnification of x2), but for the
full effect (it's quite impressive), you've got to look at two full
printed pages of text side by side.
NOTE: If you have a system that prints postscript raw (quite likely if
you have a postscript printer), you will need to add glyphs into 2.ps
(otherwise you will be comparing QT embedded glyphs to printer
substituted glyphs).
Run "ps2ps 1.ps 1_.ps" and "ps2ps 2.ps 2_.ps". Print 1_.ps and 2_.ps.
This causes gs to render the two files to postscript (your printing
system will use gs to render them to another format if you don't have
a postscript printer). For 1.ps gs uses the QT embedded versions of
your glyphs. For 2.ps it gets them from your system font files.
NOTE: The above procedure requires gs to have access to the same set
of fonts as QT. This requires a proper setup of defoma. It is most
easily done if you set QT to use Xft (enableXft=true under [General]
section in ~/.qt/qtrc) and make sure all the <dir> entries in
/etc/fonts/fonts.conf and /etc/fonts/local.conf are disabled and the
<include> line for /var/lib/defoma/fontconfig.d/fonts.conf is enabled.

I tried the comparison with Qt 3.3.6, and all seems to be well, so I'm
closing the report. If I've missed something, let us know. Thanks.
