Hi,
I am a software developer and need a lot of help!

I think this is possibly a place to get some help with a project I am working on.

I am working on an application to create PDF files from scratch. As I want to display various formatted text in the pdf file, I need to know about the font metrics to calculate lengths of strings I would write to the pdf file so I can present the text correctly. I have been reading about afm files to get these font metrics. I have also been reading about OS functions that could possibly return font metrics.

I am looking for some experienced guidance.

Where do I get AFM files? or font metrics?

Thanks in advance for your help!
