Problem with PNG images in C#

Question

Working in Visual Studio 2008. I\'m trying to draw on a PNG image and save that image again.

I do the following:

private Image img = Image.FromFile(\"fil         


        

Answer 1

You cannot create a graphics from an indexed image format (PNG, GIF,...). You should use a Bitmap (file or convert your image to a bitmap).

Image img = Image.FromFile("file.png");
img = new Bitmap(img);
newGraphics = Graphics.FromImage(img);
