From ca22e70cc4a868fdb4dec2790ec71fb9a2cfb6bd Mon Sep 17 00:00:00 2001 From: sodiboo <37938646+sodiboo@users.noreply.github.com> Date: Fri, 8 Mar 2024 13:10:55 +0100 Subject: Implement wlr-screencopy v1 (#243) * Implement wlr-screencopy * Finish the implementation Lots of changes, mainly to fix transform handling. Turns out, grim expects transformed buffers and untransforms them by itself using info from wl_output. This means that render helpers needed to learn how to actually render transformed buffers. Also, it meant that y_invert is no longer needed. Next, moved the rendering to the Screencopy frame handler. Turns out, copy() is more or less expected to return immediately, whereas copy_with_damage() is expected to wait until the next VBlank. At least that's the intent I parse reading the protocol. Finally, brought the version from 3 down to 1, because copy_with_damage() will need bigger changes. Grim still works, others not really, mainly because they bind v3 unnecessarily, even if they don't use the damage request. --------- Co-authored-by: Ivan Molodetskikh --- src/render_helpers/offscreen.rs | 1 + 1 file changed, 1 insertion(+) (limited to 'src/render_helpers/offscreen.rs') diff --git a/src/render_helpers/offscreen.rs b/src/render_helpers/offscreen.rs index 69b0be84..72c2471b 100644 --- a/src/render_helpers/offscreen.rs +++ b/src/render_helpers/offscreen.rs @@ -54,6 +54,7 @@ impl OffscreenRenderElement { renderer, geo.size, Scale::from(scale as f64), + Transform::Normal, Fourcc::Abgr8888, elements, ) { -- cgit
