I have a small program that puts some text on a tiff image. It converts a string of numbers into a barcode using the "3 of 9 Barcode" font. It has been working fine. Now I need to change the barcode font from "3 of 9 Barcode" to "IDA Code39 HR SHORT". But for some reason it does not work. I tried a few different fonts listed in Windows\Fonts. Some work and some don't. The program does not produce an error message when it does not use the specified font. It just uses a different font that looks like Arial. Any idea why is that? I can use "IDA Code39 HR SHORT" in other programs such as Word.
Thank you in advance for your help.
