* @stability: Unstable * @stability: Unstable
* *
* COGL allows the creation and the manipulation of buffers. If the underlying * The CoglBuffer API provides a common interface to manipulate
* OpenGL implementation allows it, COGL will use Pixel Buffer Objects. * buffers that have been allocated either via cogl_pixel_buffer_new()
* or cogl_attribute_buffer_new(). The API allows you to upload data
* to these buffers and define usage hints that help Cogl manage your
* buffer optimally.
*
* Data can either be uploaded by supplying a pointer and size so Cogl
* can copy your data, or you can mmap() a CoglBuffer and then you can
* copy data to the buffer directly.
*
* One of the most common uses for CoglBuffers is to upload texture
* data asynchronously since the ability to mmap the buffers into
* the CPU makes it possible for another thread to handle the IO
* of loading an image file and unpacking it into the mapped buffer
* without blocking other Cogl operations.
