Hi,


The attached ZIP file contains several files:
- A.pov = the POV-Ray source triggering the problem
- artifacts-ParmaPetit.png = result from A.pov
- artifacts-EngraversOldStyle.png = result with another font
- ParmaPetit-Italic.ttf = TTF file used to render the first pic

You can see the artifacts on the bottom-left part of the character: noise
below the baseline for one render, and jagged edges on the A's slope for
both.

The artifacts are much stronger with Engraver's Old Style Italic (from
Bitstream), but since it's a commercial font I can't attach it here. If you
have it you can give it a try.
The free font can be downloaded from
http://www.dafont.com/dl.php?os=win&fichier=parmapetit (gives a zip file
with several versions of the font -- no README so I took the liberty to put
a single file from the package in my ZIP archive)

Does the problem lies with the font files, or with POV-Ray? Both are
rendered ok by Windows' display engine.

Also, do I need to post an advisory on povray.bugreports, linking to the
present post?


That's all... If you need more info I'll be glad to help.

Thomas
