Can someone tell me if the IRIS font manager is able to scale a font to 
a size which is not available, in the same way that PostScript does? 
For example, the font courier roman is available in the following 
sizes:8,10,12,14,16,18,20,24,32 as defined in the font directory 
/usr/lib/fmfonts. Is it possible to obtain sizes 11,13,15,and 19? The man 
page for fmscalefont says "If you request a size for which there is no 
font, the Font Library routines choose the font that matches closest but 
is not larger than the requested size." This does not sound like font 
scaling to me. This is the exact behavior I am experiencing in a gl 
program I am using. A font size of 15 points using courier looks like 14 
points. But another man page on fmscalefont says "Its functionality 
parallels the scalefont operator of PostScript." A font defined to be 15 
points using PostScript is definitely larger than 14 points.

If you are running 4.05 or later, fonts which have poscript outline files in
/usr/lib/DPS/outline/base will be scaled correctly with fmscalefont.


From 4.05 Release Notes (EOE #12 Fonts)

          o In previous releases, the IRIS FM used only bitmap font
            files.  The IRIS FM now uses bitmap font files, outline
            font files in the Adobe Type 1 format, or both for a
            given typeface.  The IRIS FM scales a bitmap font when
            it cannot use an outline font and it cannot find a
            bitmap font of the right size.  The IRIS FM looks for
            Type 1 outline fonts in the directory
            /usr/lib/DPS/outline/base.
