The list of frames the Source will acquire on each page.
MSG_GET returns the size and location of all the frames the Source will acquire image data from when acquiring from each page.
MSG_GETCURRENT returns the size and location of the next frame to be acquired.
MSG_SET allows the application to specify the frames and their locations to be used to acquire from future pages. If the application isn't interested in setting the origin of the image, set both Top and Left to zero.
Defines the Left, Top, Right, and Bottom coordinates (in ICAP_UNITS) of the rectangle enclosing the original image on the original scanner. This ICAP is most useful if the Source supports simultaneous acquisition from multiple frames. Use ICAP_MAXFRAMES to establish this ability.
