My first example above is one answer, true, but that adds a lot of work when you can only use one big panel and draw all of your 'controls' inside of it. but even the 15 year old platform I'm migrating from, Borland's VCL, had several windowless controls, so it's hard to imaging winforms doesn't at least have some easy solution? I've read this stems from all winform controls being windows, so by nature they aren't transparent. even if the 2nd picture box is just empty and has a background color of Transparent, it still covers the picture below it. Place the 2nd picture box over the first. Place another PictureBox on the form and set it to a PNG. Place a PictureBox on a form and set it to a PNG. In the OnPaint handler draw 1 PNG, then draw another PNG over it, using Graphics.DrawImage for both.Is there no way to use a PictureBox or other control to contain an image with partial transparent/alpha-blended pixels, and place that over another image and have the blending be based on the image under it?įor example, this produces the results I want: I think I must be missing something obvious, but I'm unable to find this after several hours of searching.
