Resizing an Image

I'd like to load an image (bmp or jpg) of unspecified size, resize it, and save it to a memory stream for display. I thought I could load it into a picture box and resize it that way but:

a) there has to be a cleaner more direct way to do this (i.e. shouldn't I be able to do this w/o loading it into a pictureBox?)
b) it looks like pictureBox holds an orginal copy of the image and gives you back that (via pictureBox.Image.Save), so this technique doesn't really seem to work anyway.

Ideas?

Load it into an Image. Create another Image with your desired target size. Stretch Blit the source image to the target image. Save the target Image.

.getthumbnail method is useful

Thanks guys, those are some good ideas...

.getthumbnail does an awful job as it will blur the whole image

i've used getthumbnail and it hasn't blurred the images, any more than reducing the size in photoshop etc.

Maybe you had small images and didn't notice..but I assure you if you try with 1024x800 pictures it will blur them up :blush:
