Pixel size of ImageSource

Question

How can I determine the size of an ImageSource in pixels? The ImageSource object has a Height and a Width property, but they return the size in 1/96 inches..

Answer 1

Super old post, but for anyone else having problems with this, you don't have to do anything crazy or complicated.

(ImageSource.Source as BitmapSource).PixelWidth
(ImageSource.Source as BitmapSource).PixelHeight

Answer 2

There are 2 types of ImageSource: DrawingImage and BitmapSource.

Obviously, DrawingImage does not have DPI or pixel width, because it's essentially vector graphic.

On other side, BitmapSource has PixeWidth/PixelHeight and also DpiX/DpiY.
