Ok, pngview was already installed on my system and used by the PiBoy OSD. I found a png loading used in the installscript of the firmware and I can reproduce this when I want with a single line added in my scripts. It's exactly what I was looking for !

@sleve_mcdichael Thanks for your help

@simpleethat said in launchingimage adding a white background to png files:

...create launching images that would display the control scheme for every game (but that's way more effort than I really feel like going through).

That's exactly what I did for Arcade titles (with a copy of PhotoShop and a PC), but it's a big time investment. I did about ten/fifteen "major" games and then figured I'd get to the rest eventually.

I'm able to "re-use" some work for games that have the same controls. (e.g. Pac-Man and Ms.Pac-Man both use the "no buttons required" image) I also tried to make the button naming generic so that I can re-use images. If the buttons for "shoot" and "jump" are in the same place then I re-use the image. So far I've done early arcade titles which simpler control schemes.

This is probably what you are looking for.

It’s available as a package in, I think, ”optional”.

@dmmarti

Thanks ! they will come in handy

Appreciate your time and sharing them :)

I guess the fbi (image viewer) used to display the .png file does not support transparency ?

Ahh ok, that makes sense. It seems it defaults to a gray background. I wonder if there's a way to either have it default to a black background OR make the side bezels match the gray background i'm getting from the .png

@almulder

There's also this extensive vector collection by @UDb23. The advantage to using vector images is that they scale infinitely and take up very little space. Of course they can easily be converted to PNGs also if need be.

@FlyingTomahawk If your PNGs are pixelated on the edges, you are likely using 8-bit PNG format, this uses a gif style indexed pallet and has no support for alpha blending. This is the default setting on photoshop/illustrator for save-for-web output. Make sure you are saving your PNGs as 24 bit to allow for alpha transparencies around the edge pixels, and the pixelated effect will be gone. Drawback is the file size will be 5 to 10x larger.
