I create videos for youtube using stuff I wrote in Perl/Tk (Euclid). The fonts render in a very chunky fashion (I think the issue is that XQuartz is mimicking a resolution that is much less than the real resolution, so I end up with blocky fonts).

I tried all possible fonts, I really did.

In desperation, I created a library of png images by screen capturing text written in OpenOffice, in the font that I wanted. And then overrode the ->text function to replace the given text with individual pics. It worked, but let me tell you, that is quite the hack, and limited me to my predefined pics. I did this for the first 4 books. Then, to make the lines look nice, I drew a fat grey line, a slightly less fat slightly darker line, until I drew the final black line.

Finally, I ended up trying Tcl/Tk (book 5 playlist uses Tcl/Tk), which works well enough that I can just use the regular fonts.

Here are two pics for comparison (Tk screenshots). This is what Perl/Tk looks like without doing any of the fancy stuff I described in the previous paragraph. Exact same code.

Notice that even the drawing of the circle in Perl/Tk is jagged, whereas Tcl/Tk is nice and smooth. The font of the labels is Arial. The regular text is also Arial.
