Hi,

I'm painting images of various sizes into a picture box, and have the
"SizeMode" property set to "StretchImage". This looks OK when the image I am
painting is larger than the picturebox.
But when the image is smaller than the picture box, the image seems to have
some sort of filtering (bilinear?) going on resulting in a blurry picture. I
would prefer to see a nice pixellated unfiltered view of the image.

Can I set the filter type for this stretching operation? I've also tried
painting the image using Drawimage on the picturebox's graphics, but it
still seems to use some kind of filtering.

TIA,
Norvin
