Question on StretchBlt

[hutch--]

Is there any reason not to use SetStretchBltMode() and StretchBlt() for scaling bitmap images. These functions have been around for eternity and while I doubt they are fast, they have worked for a long time.

I suspect that Gdi+ would offer anti-aliasing or interpolation for better quality but honestly I haven't tested that.

Per JJ's note -

You can take a look at (GDI-Plus)

GdipSetCompositingQuality, hGr, val
GdipSetInterpolationMode, hGr, val
GdipSetSmoothingMode, hGr, val

If not too painful of a port.

Thanks, Joe. Have you seen my recent Gdi+ post?

Thanks Joe, this will be useful to me in the future.
