Hight Quality Bitmap Stretching Displaying?
-
Sometimes I need to display a bitmap much smaller then its original size, by using the
StretchBltAPI I get sadly ugly outcomes, I've noticed many picture-viewer applications have the ability of stretch-displaying pictures while maintaining high quality, some of them(IE 6.0, etc) can even do that job absolutely perfect. I wonder if I too can implement that in my own projects? Any help are appreciated. -

Any help are appreciated.for starters, see SetStretchBltMode if that doesn't do it, you'll need to explore the world of image resizing algorithms and resize the image yourself. i hear there are toolkits out there to help with this.

no method is perfect. the best you can hope for, especially when enlarging, is adequate. Cleek | Image Toolkits | Thumbnail maker
