Review follow-up: - An FP16 desktop is not necessarily HDR. Since Windows 11 22H2 an Advanced Color (WCG) SDR display is composed in FP16 scRGB too, and there 1.0 is the display's reference white, not 80 nits, so the SDRWhiteLevel scaling does not apply (Microsoft: "Reference white applies only to HDR displays"). Query IDXGIOutput6::GetDesc1 and treat the output as HDR only for DXGI_COLOR_SPACE_RGB_FULL_G2084_NONE_P2020, the documented Win32 check; a non-HDR FP16 frame now gets just the scRGB -> sRGB transfer. Without IDXGIOutput6 (before Windows 10 1803) FP16 can only mean HDR. - The SDR white level is now Option: a failed query or a reported 0 is "unknown" on both the initial and the refresh path, an HDR output with an unknown level logs a warning and keeps the 80-nit assumption until the periodic re-query succeeds. DISPLAYCONFIG_DEVICE_INFO_GET_SDR_WHITE_LEVEL needs Windows 10 1709, not 1703 as an earlier message said.

scrap
Scrap records your screen! At least it does if you're on Windows, macOS, or Linux.
Usage
[dependencies]
scrap = "0.5"
Its API is as simple as it gets!
struct Display; /// A screen.
struct Frame; /// An array of the pixels that were on-screen.
struct Capturer; /// A recording instance.
impl Capturer {
/// Begin recording.
pub fn new(display: Display) -> io::Result<Capturer>;
/// Try to get a frame.
/// Returns WouldBlock if it's not ready yet.
pub fn frame<'a>(&'a mut self) -> io::Result<Frame<'a>>;
pub fn width(&self) -> usize;
pub fn height(&self) -> usize;
}
impl Display {
/// The primary screen.
pub fn primary() -> io::Result<Display>;
/// All the screens.
pub fn all() -> io::Result<Vec<Display>>;
pub fn width(&self) -> usize;
pub fn height(&self) -> usize;
}
impl<'a> ops::Deref for Frame<'a> {
/// A frame is just an array of bytes.
type Target = [u8];
}
The Frame Format
- The frame format is guaranteed to be packed BGRA.
- The width and height are guaranteed to remain constant.
- The stride might be greater than the width, and it may also vary between frames.
