This function does not process image pixels.
The IG_ISIS_drv_send_dither function sends the downloadable dither pattern stored in one of the downloable dither tags down to the scanner.
Before calling IG_ISIS_drv_send_dither, you should have already called IG_ISIS_drv_read_dither_file with the tag specified in nTag to obtain a downloadable dither pattern from the user or called IG_ISIS_tag_set_long on nTag to configure a downloadable dither pattern. Use IG_ISIS_drv_send_dither to actually forward the dither pattern data to the scanner hardware.
