Resize the Bitmap problem

Resize the Bitmap problem

Visual Studio193
I want to display a resized picture to the window with the StretchBlt

functions from the Mem DC to device dc.

I find if the output picture is very small than the original one, there will

be a lot of black dots and strips on the picture.

Does windows api have a better function to do the resizing?

See SetStretchBltMode. Experiment with different modes, see which one

gives you the best result.

With sufficient thrust, pigs fly just fine. However, this is not

necessarily a good idea. It is hard to be sure where they are going to

land, and it could be dangerous sitting under them as they fly

overhead. -- RFC 1925
