Using PostScript, I would like to print text in a 'special' way. I do not know if what I want is possible without designing a font, which I do not want to do as I am not sure how. This may be a little hard to follow, but here goes. I want to print a 'fat' letter with a 'skinney' letter inside it. The following is an 'I' trying to show what I want. xxxxxxxxxx xx x xx x xx x xx x xxxxxxxxxx The Xs are black and the blank area is white. Also, there would be a narrow white line in the top and bottom. That is, make the letter with a wide felt pen (black) and then in the same place, make it again with a small brush (white). I do not want to change the fonts bounding box width or hight. I want to change the width of the 'stroke' while keeping the same 'size'. I hope that this is clear! Thanks in advance for any help.
