Transparent PNG image (with TImageList) in a TMainMenu

Question

I want to load a PNG with transparent background in a TImageList and use it in a TMainMenu (via TAction).
However, in Delphi the background is just black. Is PNG support onl

Answer 1

I had been using TPngComponents since Delphi 7. That provide very good png support for most of the delphi build-in / third party components. Embarcadero had purchased another well know Open Sources PNG Supporting component know as TPngImage and build into Delphi's native graphic support in later Delphi versions. So when I changed to Delphi 2010, I think Delphi had native support now and test out the native support but find that the alpha support is not good enough.

So I had used back that TPngComponents again and it had better support for most components, including main menu. I think that package should be usable to DXE with limited modification.

edit : Thanks for Uwe Raabe for pointing out the product Codegear (now Embarcadero) purchased was another component TPngImage rather then the TPngComponent.
