[magick-users] Font widths

[Scott Nebor]

Formally, I am having difficulty finding documentation to support how I
thought true type fonts should scale.   The article
http://www.microsoft.com/typography/otspec/TTCH01.htm is probably the best
article that I could find.  Notably, the sections on scaling a glyph and
grid fitting a glyph outline.

That being said, in trialing how different true fonts physically print, and
also appear on screen, I found that they support my ideas.  The width and
height both scale proportionally.  Unfortunately, all I have at my disposal
are Microsoft office programs, and their corresponding printer output.

Normally I would expect some distortion at different font sizes.  However,
the way that imagemagick renders some lines of text can be dramatically
different depending on the font size

Really?  Do you have a reference for that understanding?  I never heard
that before, and I never expected it either, for proportional fonts.

I'd think it is a hard problem, for imagemagick or anything else, unless
fractional-pixel positioning were done.
