This function creates a CoglBitmap which internally references a CoglBuffer. The map and unmap functions will divert to mapping the buffer. There are also now bind and unbind functions which should be used instead of map and unmap whenever the data doesn't need to be read from the CPU but will instead be passed to GL for packing or unpacking. For bitmaps created from buffers this just binds the bitmap. cogl_texture_new_from_buffer now just uses this function to wrap the buffer in a bitmap rather than trying to bind the buffer immediately. This means that the buffer will be bound only at the point right before the texture data is uploaded. This approach means that using a pixel array will take the fastest upload route if possible, but can still fallback to copying the data by mapping the buffer if some conversion is needed. Previously it would just crash in this case because the texture functions were all passed a NULL pointer. http://bugzilla.clutter-project.org/show_bug.cgi?id=2112 |
