Structure of parameters describing scale |
Scale a source bit map to a non-overlapping destination bit map.
Overlapping source and destination bitmaps are not supported Make sure that you provide enough memory for the destination bitmap to hold the result
In the destination bitmap only the area where the scaled source bitmap is put into is changed. A frame of the old bitmap is left.
Pass a BitScaleArgs structure filled with the following arguments to this function:
bsa_DestWidth and bsa_DestHeight will be set by this function

Get the scaling result that BitMapScale would. |
