You can set the path and name of the file to scan as seen in the Setting the TWAIN Image Acquisition Mode section. If the scanner allows you to change the image file format, you can change it with the SetCapabilityOneNumValue function/method of the BiTWAIN DLL/OCX. The ICAP_IMAGEFILEFORMAT TWAIN capability specifies the file format of the scanned image. You can get and set this value if the scanner supports this capability.
