scrap

Scrap可以记录您的屏幕！如果您使用的是Windows、macOS或Linux，它至少可以做到这一点。

使用方法

[dependencies]
scrap = "0.5"

它的API简单到极致！

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];
}

帧格式

• 帧格式保证是 打包的BGRA。
• 宽度和高度保证保持不变。
• 步进可能大于宽度，并且它可能在帧之间变化。
