How to draw smooth images with C#?

Question

I\'m trying to draw images on a C# form (in PictureBoxes, as well as using Graphics.DrawImage()), and am looking for a way to draw them smooth. The images

Answer 1

When drawing the image to a canvas, you can change the interpolation mode to something nicer then nearest neighbor to make resized images smooth:

Graphics g = ...
g.InterpolationMode = InterpolationMode.HighQualityBicubic;
g.DrawImage(...);

You'll need to add System.Drawing.Drawing2D to get the InterpolationMode enum.

Using PictureBox will be a problem - it doesn't expose an InterpolationMode property, so you'll need to roll your own or download one.
