Will, I'd personally open 2 sample files for all three types in a hex editor, and see if I can find the propery values in them and try and find a pattern to where they are located. After that I would write a program to open the file up, index the those locations and extract the data. There also may be some kind of font api out there. Why not do a quick google search? Hey, look at the first result!
I am honestly thankful & grateful to your very--EXTRA--quick reply to my thread. I have actually done before what you are suggesting me. My code succeeded in some font files but it failed in other font files. Ain't there a standard font header structure that we can use to obtain the information we want? For example, there is a BITMAPFILEHEADER or BITMAPCOREHEADER for obtaining a bitmap information from a bitmap file.
