Clutter.Stage.read_pixels

### Method

# Clutter Stageread_pixels

#### Declaration [src]

    guchar*
    clutter_stage_read_pixels (
      ClutterStage* stage,
      gint x,
      gint y,
      gint width,
      gint height
    )

#### Description [src]

Makes a screenshot of the stage in RGBA 8bit data, returns a linear buffer with `width` * 4 as rowstride.

The alpha data contained in the returned buffer is driver-dependent, and not guaranteed to hold any sensible value.

#### Parameters

`x`

  Type: `gint`

  X coordinate of the first pixel that is read from stage.

`y`

  Type: `gint`

  Y coordinate of the first pixel that is read from stage.

`width`

  Type: `gint`

  Width dimension of pixels to be read, or -1 for the entire stage width.

`height`

  Type: `gint`

  Height dimension of pixels to be read, or -1 for the entire stage height.

#### Return value

Type: An array of `guchar`

A pointer to newly allocated memory with the buffer or `NULL` if the read failed. Use `g_free()` on the returned data to release the resources it has allocated.

The caller of the method takes ownership of the returned data, and is responsible for freeing it.
