Remarks:

The application shall create a new HIGDIBINFO object containing information about the image, and pass through the lphDIB parameter. ImageGear owns the HIGDIBINFO object after exiting from the callback, and eventually deletes it. If the image being saved has a palette, it should be passed with HIGDIBINFO as well.
