image quality in picture box

Have loaded the image to picturebox in 开发者_如何学运维zoom mode. but the text is not clear. how to improve the quality of the image with fixed picture box size.

How about subclass Picture Box and interpolate yourself.

set PictureBoxSizeMode to AutoSize or find a better quality image.

You can subclass it, but you don't have to do all the painting yourself:
