How to view a character with glyphshow?

问题

/Helvetica findfont setfont
/a glyphshow

The interpreter give out a nocurrentpoint error. How to show a character with glyphshow in PostScript?

Thanks.

回答1:

You have to indicate where to put it. (This is the meaning of the "nocurrentpoint" error.)

Oh, you'll also need to scale the font before setting it. The default font size is 1pt (1/72 inch) [very small]. (Not an error per se, but a foreseeable obstacle in your path.)

As pipitas (our SO Postscript top-dog) recommends, here's a complete example:

%!
/Helvetica findfont 24 scalefont setfont   %or: /Helvetica 24 selectfont
