I thought I gave an example of this in my email anyway? I knew this part. > They will not appear if you use the :unscaled postfix in your > fontpath entries. Ahhh that might help explain things a little. I hadn't thought of that.

I don't think so, because when using the '-*' call to XListFonts as described in the gfontsel sources doesn't yield #12 for urw. That can only mean that xfs is using the default settings for my system(?). Using `xlsfonts | less` also doesn't show #12. How do you explain that? Besides a bitmapped font of size 12 should also include an average width field (the zero in -p-0-iso8859) -- all the rest do. FWIW, wouldn't it make sense for FontLoader to use a pattern that includes the screen DPI setting? Or at least FontInfo::query() when searching for a suitable scalable font? Or we should at least be trying to match a font that is as close as possible to the screen dpi setting within FontInfo::getFontName() for non-scaled fonts. If scalable fonts are enabled then people like Peter D. with 140dpi screens will get a scaled font of the right dpi rather than him having to set a really high zoom level. The scaled result may also appear slightly different -- 36pt 75dpi versus say 18pt 140dpi when viewed on a 140dpi screen. And if scalable fonts are off then he would get a match for 100dpi fonts instead of the more likely 75dpi. Depending upon the font this could be the difference between readable and unreadable since some fonts change shape at smaller point sizes to make them more readable. > Allan> I have a bit more work to do on cleaning up the font code and > Allan> then I'll send a patch for inspection that will provide both > Allan> the option to resize bitmapped fonts and to enable/disable all > Allan> font scaling (I just need to add another(!) lyxrc variable). > > Please make sure you understand how fonts work first.

Current behaviour is just being extended to distinquish between types of scalable fonts (outline ones and bitmapped ones). The further discussion about dpi above only exists in emailed electrons at present. [...] > PLEASE don't do that! We do certainly not need to have such ugly hacks.
