Constructor
CoglTexture2Dnew_with_format
Declaration [src]
CoglTexture*
cogl_texture_2d_new_with_format (
CoglContext* ctx,
int width,
int height,
CoglPixelFormat format
)
Description [src]
Creates a low-level CoglTexture2D texture with a given width and
height that your GPU can texture from directly.
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-
Type:
CoglContextA
CoglContext.The data is owned by the caller of the function. width-
Type:
intWidth of the texture to allocate.
height-
Type:
intHeight of the texture to allocate.
format-
Type:
CoglPixelFormatFormat of the texture to allocate.
Return value
Type: CoglTexture
A new CoglTexture2D object with no storage yet allocated.
| The caller of the function takes ownership of the data, and is responsible for freeing it. |
