Comments

The DTWAIN_EnableFeeder function determines whether to use the document feeder when acquiring images. If bEnable is TRUE, the document feeder is used to acquire images. If bEnable is FALSE, the alternate method is used (usually the alternate method is the flatbed portion of a scanning device). If DTWAIN_EnableFeeder is not called, the document feeder will be used. Note that this function will always return FALSE if the device does not have a document feeder.

This function is useful if you have a scanning device that uses both a flatbed and document feeder, and your application wants to choose one over the other. By default, enabling the document feeder will always allow the pages to be fed automatically. To turn of the automatic feeding of the pages, call DTWAIN_EnableAutoFeed(Source, FALSE).
