I have a Topaz signature pad. It captures the customer's signature at the end of a sale. It can save the signature to a string (it is a very long string), a sig file which I guess would be Topaz proprietary, bmp, jpg, png, tiff and wmf and emf. I have it saving the signatures as an jpg image file. It works. I can print the jpg on the receipt (a VFP9 report). My problem is the signature is very small. I can't find a way via Topaz commands to make the signature larger. The jpg file contains a lot of whitespace aroung the actual signature. If I could somehow (from VFP), open the jpg, find the 1st instance of a black dot in the jpg (that would be where the actual signature starts), maybe I could automatically crop the jpg and resave it ending up with an image that ONLY contains the actual signature (so leaving out all the whitespace around the actual signature). I've looked at using the VFP GDIPlus library and maybe the GDIPlus X library on github (i really don't understand how to download that library from github).
Can anyone tell me the easiest way to get from point a to b on this?
Thanks,
John
