I need to resize a bmp like the resize works in MS Paint - that is with no antialiasing . Anyone know how to do this in c# or vb.net ?
You can use the Image.GetThumbnailImage
method. I am not aware of it antialiasing.
EDIT: I was thinking of thumbnail images since I recently used this in a project. But you are just asking for resizing in general. This method may not result in good quality large resizing.
