| 项目描述: |
The ability to draw an image on the screen that is a different size than the original source image is incredibly easy with Win32's GDI StretchBlt function and its variants. However, using StretchBlt with large images, especially with a large amount of stretch, is very slow. Also, shrinking images with StretchBlt often produces poor image quality. This article provides some simple techniques to get around the performance and image quality limitations of StretchBlt.
