2 beginner questions: 1) Is there a better way to scale an array rather than using concatmatrix? Plain 'mul' does not seem to work. (Note: I'm referring to a general array (used for font scaling), not the CTM.) Specifically, my current code to define an operator FS that takes a rotation angle and point size and generates a font, runs like this: /FS {findfont exch /angle exch def exch /pt exch def [angle cos angle angle sin angle sin neg angle cos 0 0] [pt 0 0 pt 0 0] [0 0 0 0 0 0] concatmatrix makefont} bind def used as: 12 90 /Times-Roman FS to generate a 12-pt font rotated 90 degrees. This seems rather clumsy. Is there a better way? 2) What's the appropriate vertical displacement for superscripts and subscripts relative to the bounding box/x-height/... of the base character? Thank you for any insights. Henning Schulzrinne
