*
*
* Based on (at least) the following plug-ins:
* Screenshot
* GIF
* Randomize
*
* Any suggestions, bug-reports or patches are welcome.
*
* This plug-in interfaces to the TWAIN support library in order
* to capture images from TWAIN devices directly into GIMP images.
* The plug-in is capable of acquiring the following type of
* images:
* - B/W (1 bit images translated to grayscale B/W)
* - Grayscale up to 16 bits per pixel
* - RGB up to 16 bits per sample (24, 30, 36, etc.)
* - Paletted images (both Gray and RGB)
*
* Prerequisites:
* This plug-in will not compile on anything other than a Win32
* platform. Although the TWAIN documentation implies that there
* is TWAIN support available on Macintosh, I neither have a
* Macintosh nor the interest in porting this. If anyone else
* has an interest, consult www.twain.org for more information on
* interfacing to TWAIN.
*
* Known problems:
* - Multiple image transfers will hang the plug-in. The current
* configuration compiles with a maximum of single image transfers.
