PopupControl Background transparency problem

While making a nice splashscreen with the PopupControl I ran into a problem with the transparancy of my image and I wanted to share the solution for this problem I got from CodeJock support.

I used this 32 bit alphachannel image as the BackgroundBitmap.

On the splashscreen I added an Item which I wanted to update with the loading process.

Loading Plugins, Loading windows, etc. But with this image the Item was not visible. Codejock Support found out this is a Microsoft problem (http://msdn.microsoft.com/en-us/library/windows/desktop/ms633556(v=vs.85).aspx). There is a workaround. Use a 24 bit image and set the MaskColor to 0xFF00FF (The purple color of this image). The new image:

 

The only thing I had a little struggle with was how to set the MaskColor. I used an ImageManager with the image set at designtime. Setting the MaskColor on the ImageManager.Icons and then adding the icons to the PopupControl.Icons didn't work. But first setting the MaskColor on the PopupControl.Icons

and then adding the ImageManager.Icons to the PopupControl.Icons did work!

 

I also attached a zip file I have send to CodeJock Support which contains the project that reproduces the problem (uploads/6226/SplashScreen1.zip).

 

Hopefully there will be more people who can use this workaround to accomplish a nice splashscreen. :)
