Shrinking Pictures

[John G Duffy]

Is there a way to shrink pictures? Stretchblt will expand them but how do you do the opposite? If I try to pass a target Picturebox to Stretchblt that is smaller than the source, it gives RC = 0.
Thanks in advance

StretchBlt does shrink images. You must have made some mistake. The destination height and width, the scalemode etc are the parameters to check.

PaintPicture does it too, but it is quite slow. Nevertheless, ou can use paintpicture to make the parameters work, and then port them to StretchBlt.

Shree. Thanks for your reply. Believe it or not, while twiddling my thumbs, I decided to search Codeguru forum for some suggestions and got a hit for a post I REPLIED to a couple of weeks ago. My reply was the solution to my current problem. I guess Senility is creeping in. I even posted a complete working sample in my reply.
