I want to set the fontmap to be used when saving the file. I write to
the canvas using Arial and would like to get either Arial or Courier in
the resulting .ps instead of MsSansSerif... I haven't found any sample
on the net. Has anyone done this before with success ? What is the
format of the "fontmap" option ?
I needed to do something similar some time ago and also found no examples.
I'm not sure if it is the correct way to do it, but the code below appears
to work.
When you press the 'Print' button it creates a fontmap array which
substitutes 'Arial 12' for all occurences of 'Courier 12' and 'Arial-Bold
14' for 'Courier 14'. It then dumps the postscript to a file.
Hope that helps,
Richard Townsend
