classmethod new_with_size(context, bytes)

Parameters:

• context (Cogl.Context) – A Cogl.Context

• bytes (int) – The number of bytes to allocate for vertex attribute data.

Returns:

A newly allocated Cogl.AttributeBuffer. Never None.

Return type:

Cogl.AttributeBuffer

Describes a new Cogl.AttributeBuffer of size bytes to contain arrays of vertex attribute data. Afterwards data can be set using Cogl.buffer_set_data() or by mapping it into the application’s address space using Cogl.buffer_map().

The underlying storage of this buffer isn’t allocated by this function so that you have an opportunity to use the Cogl.buffer_set_update_hint() and cogl_buffer_set_usage_hint() functions which may influence how the storage is allocated. The storage will be allocated once you upload data to the buffer.

Note: You can assume this function always succeeds and won’t return None
