1) Displaying regularly-spaced matrix of my character set and capturing it as a bitmap; then 2) dividing this up to capture the single-character bitmaps into a vector; and 3) indexing into this vector by the character set index to pull out the bitmaps to insert into my image to re-produce the character string desired. So, to do the first step, enlarge the font in your J window, enter 16 16$a. and screen-capture the result. Cut out the relevant section of the image with a size that is some integral multiple of the character matrix you see. E.g. if you're looking at 14x16 rows and columns of usable characters, it would be nice if the image is something like 378x224 (=27 14 * 14 16). This way, you can blindly partition it into distinct cells, each containing one character. This is perhaps not the nicest way, but it's fairly simple.
