I’ve a problem getting images from a fi7160 with PaperStream TWAIN driver, scanning B&W image (any binarization algorithm).
When I issue a DAT_IMAGEMEMXFER providing a buffer with 48K I get the first block of the scanned image. Then, I continue reading until I get TWRC_XFERDONE. The problem is that each time the buffer is filled the PIXELFLAVOR changes and the result is an image with inverted Black & White. Next block cames ok, and then another inverted image block, …
It seems to be a bug of the driver or there is any way to know the pixelflavor of an image block transfered from scanner to application?
