Since we don't support rendering to compressed formats, we implement this by using a compatible format with the same bpp as the compressed format. However, we need to take into account that the underlying compressed image bpp is computed for a full block, so when we specify regions on the compressed image, we need to divide offsets and dimensions by the block size. This works well for anything that copies to a compressed format using the TLB, but it doesn't specifically address copies from compressed formats to other compatible images. These go through the blit path and require to copy by blitting (texturing) from the compressed format to another format. In this case, we choose a comptible format with the per-texel bpp (not the block bpp) of the compressed format so it matches the setup for the blit operation.

`Mesa <https://mesa3d.org>`_ - The 3D Graphics Library ====================================================== Source ------ This repository lives at https://gitlab.freedesktop.org/mesa/mesa. Other repositories are likely forks, and code found there is not supported. Build & install --------------- You can find more information in our documentation (`docs/install.rst <https://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_): .. code-block:: sh $ mkdir build $ cd build $ meson .. $ sudo ninja install Support ------- Many Mesa devs hang on IRC; if you're not sure which channel is appropriate, you should ask your question on `Freenode's #dri-devel <irc://chat.freenode.net#dri-devel>`_, someone will redirect you if necessary. Remember that not everyone is in the same timezone as you, so it might take a while before someone qualified sees your question.
