Struct xray::OpenGlScreenshotCaptor

pub struct OpenGlScreenshotCaptor {}

Captures a screenshot using gl::ReadPixels

To use this screenshot captor, OpenGL must be able to load function pointers. If you use Piston or Glutin, this is likely already the case.

If you use a lower level library like gl directly, you may need to call gl::load_with(|symbol| glfw.get_proc_address(s))) or similar, depending on your choice of gl library and context library.
