Constructor

CoglBitmapnew_for_data

Declaration [src]

CoglBitmap*
cogl_bitmap_new_for_data (
  CoglContext* context,
  int width,
  int height,
  CoglPixelFormat format,
  int rowstride,
  uint8_t* data
)

Description [src]

Creates a bitmap using some existing data. The data is not copied so the application must keep the buffer alive for the lifetime of the CoglBitmap. This can be used for example with cogl_framebuffer_read_pixels_into_bitmap() to read data directly into an application buffer with the specified rowstride.

Stability:	Unstable
Available since:	1.10

Parameters

`context`	`CoglContext`
	A `CoglContext`.
	The data is owned by the caller of the function.
`width`	`int`
	The width of the bitmap.
`height`	`int`
	The height of the bitmap.
`format`	`CoglPixelFormat`
	The format of the pixel data.
`rowstride`	`int`
	The rowstride of the bitmap (the number of bytes from the start of one row of the bitmap to the next).
`data`	`uint8_t*`
	A pointer to the data. The bitmap will take ownership of this data.
	The data is owned by the caller of the function.

Return value

Returns:	`CoglBitmap`
	A new `CoglBitmap`.
	The caller of the function takes ownership of the data, and is responsible for freeing it.
