 The control's public `GdipLoadPicture` method can load 32-bit alpha transparent PNGs in `StdPicture` objects which can be assigned to control's `Picture` property. In the sample `Form1` such alpha transparent image is loaded to a `StdPicture` and is assigned both to a built-in `VB.Image` control and to an `AlphaBlendImage` control to compare difference in output.
