of course it is possible, everytime you are doing a fingerprint check there must be a "signal", to indicate that the fingerprint acquisition is done, right? during the acquisition process you can save the 1 & 0 data you get from the sensor into somekind of buffer in the "image acquisition system", then using the "signal" I mentioned before, save the buffer into a *.BMP file (perhaps by first transferring the raw data from the "image acquisition system" to the PC as needed). AFAIK, the windows 3.0 BMP file format is very much stright forward, you only need to add a couple of header addition. Some hints on the BMP file format (read Charles Petzold's -- Programming Windows 5th Edition book for detailed explanation) :zkai2000 said:but i cant actually save it manually as bmp file coz im doing a fingerprint recognition system. If it can be easily saved as bmp automatically then my fingerprint features extraction part is solved...issit possible?
