.Net & C#: Trying to have a transparent image on a button (assigned from IDE)

Question

Using VS2005 and C#.

Having a button in a form and an image from a resource, the image does not have transparency.

How can I have transparency when assigning the image from the IDE ?

Thank you.

Answer 1

Open the image in an image editor (Paint.NET and GIMP are free) and add the transparencies wherever you need to.

It will all work once the image actually has transparent pixels.

You can also use a couple methods of the Bitmap class to do this:

Bitmap b = Properties.Resources.MyImage;
b.MakeTransparent(b.GetPixel(0, 0));
