Comments The DTWAIN_GetNumAcquiredImages function returns the number of images acquired from the Source Source for acquisition number AcquireNum. For most acquisitions, the images are Device Independent Bitmaps (DIBs). For buffered acquisitions using compression, the image data that is returned describes the raw data bytes of the image (for example, a TIFF file, JPEG file, etc.).
Acquisition numbers are numbered from 0 to n-1 where n is the total number of attempted acquisitions.
