pub enum ImageSource {
Canvas(String),
Img(String),
Shot(String),
}Available on crate feature
slider only.Expand description
图源:CSS 选择器指向的 <canvas> / <img> / 截图块。
Variants§
Canvas(String)
一个 <canvas> 元素(直接 getImageData)。
Img(String)
一个 <img> 元素(按自然尺寸离屏绘制后取像素;跨域无 CORS 会 taint 不可读)。
Shot(String)
一个跨域 taint 锁死的 <img>(getImageData 读不到像素,如顶象拼图)。库会浏览器级
截图(taint-proof)该元素、注入隐藏 img 后做内容匹配(GapMethod::ContentNcc)。
