Constructor

CoglTexture2Dnew_from_file

Declaration [src]

CoglTexture2D*
cogl_texture_2d_new_from_file (
  CoglContext* ctx,
  const char* filename,
  GError** error
)

Description [src]

Creates a low-level CoglTexture2D texture from an image file.

The storage for the texture is not allocated before this function returns. You can call cogl_texture_allocate() to explicitly allocate the underlying storage or preferably let Cogl automatically allocate storage lazily when it may know more about how the texture is being used and can optimize how it is allocated.

The texture is still configurable until it has been allocated so for example you can influence the internal format of the texture using cogl_texture_set_components() and cogl_texture_set_premultiplied().

Parameters

`ctx`	`CoglContext`
	A `CoglContext`.
	The data is owned by the caller of the function.
`filename`	`const char*`
	The file to load.
	The data is owned by the caller of the function.
	The string is a NUL terminated UTF-8 string.
`error`	`GError **`
	The return location for a `GError*`, or `NULL`.

Return value

Returns:	`CoglTexture2D`
	A newly created `CoglTexture2D` or `NULL` on failure and `error` will be updated.
	The caller of the function takes ownership of the data, and is responsible for freeing it.
