   source as RawBitmap,
   dstWidth as Integer,
   dstHeight as Integer) as RawBitmap

Parameters

source
The source RawBitmap to work with. This can be any valid RawBitmap instance with 1, 2, 3 or 4 channels.
dstWidth
The width of the destination RawBitmap. If this is less than one then a nil will be returned.

Returns

RawBitmap
