We have PINPads that create signatures using a 3-byte ASCII signature format (see attached file 3ba [url removed, login to view]). We want to save the signatures in the 3-byte ASCII signature format because the amount of space is so much smaller than a BMP or a JPEG, but we need the ability to convert that format to an web-friendly graphic format on-the-fly to be displayed on a PHP page. The image format can be JPEG, PNG, BMP. etc. (whichever is easiest). The function can be written in PHP or javascript. It would accept the input of the 3-byte ASCII signature format and output the image file (either to disk or as base64 output, whichever is easiest). A sample graphic and signature are attached ([url removed, login to view]). We found a VB.NET version ([url removed, login to view]) and a C version([url removed, login to view]) that I've also attached for reference, but we need a PHP/Javascript version.
