Masked/Transparent .PNG as background/wallpaper?
So, I swear this used to work. I have a company logo that is a transparent .PNG image. However, the frame of the image is filled with opaque black (or sometimes white) when I set it as my wallpaper.
I find this really strange, as the transparency shows up correctly in the .PNG file's Explorer Icon - even in the Personalize -> Desktop Background menu.
Why does Windows show the icon with transparency but the image itself without it?
If I set the background to Center or Tile (where Windows doesn't have to resample it) then the raw RGB colors show up, including where they should be masked out by the .PNG's Alpha. If I set it to Fit or Fill (where Windows has to resample it) then the pixles which should be masked show up as solid black. It clearly is a transparent .PNG, and it is reading that transparency, it just isn't using it.
So,
1. Why does transparency work in the explorer Icons and Tiles, but not as a desktop background?
2. Is it possible to get Windows to read the image correctly everywhere, not just in some places?
The image doesn't fit the entire screen, so I'd just like the transparent parts to be transparent and show my desktop background color, in this case grey... like it shows up in the icon.
(Also yes, I'm just going to make a solid version with the right background color so it matches. This still bugs me though, and any help is appreciated )
