I'm looking for a way to have images on invisible form that allow alpha transparency and allow to place and use buttons/labels etc.

I've tried this Transparent background on winforms?, layered window and many more, nothing fully successful. I've ended up with such failures http://imgur.com/a/t6nmF

Transparency key only makes one color transparent, which doesn't work on images that have smooth color gradients on the edges.

First of all, are you certain that your image has a transparent background?

Layered window is exactly what you should use to achieve the desired effect. Since you don't give much details, I don't know what's wrong with your implementation. Try to use the PerPixelAlphaForm from the following article: Per Pixel Alpha Blend in C#. When used correctly, it will work (even though the article is really old).

  • I've used Layered window and the image worked fine, but the problem is that in layered window you cannot add buttons/labels etc, only the image will be drew (its good for starting screens and such, but I need fully functional program). Thanks for that article tho, I'll try to do as it says. – Erexo Feb 20 '17 at 16:18
