How to: Convert Bitmap to Image?

[Danyel Meyer - dialog-it GmbH]

Hallo!

When using OpenNetCF´s ButonEx I´d like to put transparent images onto them.
I have created a function that fakes transparency of a given Image-object
and returns a Bitmap-object.
The ButtonEx of the SDF only accepts Image-objects for its Image-attribute,
so how do I convert a Bitmap-object to an Image-object?

Thanks in advance,

Since Bitmap inherits from Image you can assign it to the Image property of
ButtonEx.

Bitmap bmp = new Bitmap("somefile.gif");
buttonEx1.Image = bmp;

Thanks Peter, but that is what I have tried, and it does not work. I get an
"Not supported" exception on it... thats why I asked

Well, ok...

It needs something like the following to work:

buttonEx1.Image = New Bitmap(myFunction(New Bitmap(the Image),
Color.WhatEver))

Thanks Peter

It should work, but maybe try to explicitly cast it:

Bitmap bmp = new Bitmap("mypic.bmp");
buttonex1.Image = (Image)bmp;
