Method decode_bgr

rustcv-camera/src/frame.rs:186–190

Decode this frame into a BGR [`Mat`]. 将此帧解码为 BGR [`Mat`]。 This is a convenience method that allocates a new Mat. For zero-allocation decoding, use [`Camera::read_decoded()`] or [`VideoCapture::read()`] which reuse an existing Mat. 这是一个便捷方法，会分配新的 Mat。 如需零分配解码，请使用可复用现有 Mat 的 [`Camera::read_decoded()`] 或 [`VideoCapture::read()`]。

    /// 如需零分配解码，请使用可复用现有 Mat 的
    /// [`Camera::read_decoded()`] 或 [`VideoCapture::read()`]。
    pub fn decode_bgr(&self) -> Result<Mat> {
        let mut mat = Mat::new();
        crate::decode::decode_frame(self, &mut mat, None)?;
        Ok(mat)
    }
}
