Title: Video Modes and Colour Depth
Post by: Xander314 on June 13, 2011, 04:55:32 pm

For a video tutorial I am making on windowing and video modes, I was wondering what happens when we give our video mode something like 11bit colour.

It is invalid for fullscreen mode, but what happens for windowed applications?

Also, to clarify, when a bad video mode is passed to the window constructor, does it revert to sf::VideoMode::GetDesktopMode()?

If the pixel depth is not directly supported, the closest valid one is chosen.

Only in fullscreen. In windowed mode you can use any width/height and there's always a valid depth that can be used.

So even in windowed mode, the bit depth is corrected to 8/16/32 or something?
