### Function

# Shell Screenshotcomposite_to_stream

#### Declaration [src]

    void
    shell_screenshot_composite_to_stream (
      CoglTexture* texture,
      int x,
      int y,
      int width,
      int height,
      float scale,
      CoglTexture* cursor,
      int cursor_x,
      int cursor_y,
      float cursor_scale,
      GOutputStream* stream,
      GAsyncReadyCallback callback,
      gpointer user_data
    )

#### Description [src]

Composite a rectangle defined by x, y, width, height from the texture to a pixbuf and write it as a PNG image into the stream.

This function completes asynchronously. Use `shell_screenshot_composite_to_stream_finish()` inside the `GAsyncReadyCallback` to obtain the result of the operation.

#### Parameters
