From a65d6a11cb82719a649110a8deaeb8f87e1c374b Mon Sep 17 00:00:00 2001 From: Greg V Date: Sun, 31 May 2020 16:53:57 +0300 Subject: Add custom window background/clear color (incl. transparency) support, fixes #272 wgpu would currently ignore the alpha: https://github.com/gfx-rs/wgpu/issues/687 glow (and naively patched wgpu) requires premultiplied alpha, so if you don't multiply the RGB by the A right now, the semi-transparent color would be wrong (too bright). winit with_transparent doesn't seem necessary. --- glow/src/window/compositor.rs | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'glow/src/window') diff --git a/glow/src/window/compositor.rs b/glow/src/window/compositor.rs index 2f504ff7..c93191b0 100644 --- a/glow/src/window/compositor.rs +++ b/glow/src/window/compositor.rs @@ -21,7 +21,12 @@ impl iced_graphics::window::GLCompositor for Compositor { ) -> (Self, Self::Renderer) { let gl = glow::Context::from_loader_function(loader_function); - gl.clear_color(1.0, 1.0, 1.0, 1.0); + gl.clear_color( + settings.background_color.r, + settings.background_color.g, + settings.background_color.b, + settings.background_color.a, + ); // Enable auto-conversion from/to sRGB gl.enable(glow::FRAMEBUFFER_SRGB); -- cgit
