Description

Converts a bitmap to a DIB of a specified pixel format.

Call InternalGetDIB to convert a bitmap to a DIB of a specified pixel format. InternalGetDIB returns True if the conversion is successful and False otherwise.

The parameters of InternalGetDIB are listed in the following table, together with their meanings.

Parameter	Meaning
Bitmap	The handle of the source bitmap.
Pal	The handle of the source palette.
BitmapInfo	The buffer that will receive the DIB's TBitmapInfo structure. A buffer of sufficient size must be allocated prior to calling this function.
Bits	The buffer that will receive the DIB's pixel data. A buffer of sufficient size must be allocated prior to calling this function.
