public OverlayRectangle.raw (Buffer pixels, int render_x, int render_y, uint render_width, uint render_height, OverlayFormatFlags flags)
Creates a new video overlay rectangle with ARGB or AYUV pixel data.
The layout in case of ARGB of the components in memory is B-G-R-A on little-endian platforms (corresponding to BGRA) and A-R-G-B on big-endian platforms (corresponding to ARGB). In other words, pixels are treated as 32-bit words and the lowest 8 bits then contain the blue component value and the highest 8 bits contain the alpha component value. Unless specified in the flags, the RGB values are non-premultiplied. This is the format that is used by most hardware, and also many rendering libraries such as Cairo, for example. The pixel data buffer must have Meta set.
