This callback function is called before writing the image header.

Declaration:

typedef AT_ERRCOUNT (LPACCUAPI LPFNIG_DIB_GET_EX)( 
        LPVOID lpPrivate, 
        HIGDIBINFO* lphDIB
);

Arguments:

Return Value:

Returns an error count.

Supported Raster Image Formats:

All pixel formats supported by ImageGear for C and C++.

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.
