Most of them already redirected to https anyway, so we might as well avoid the redirection and the security implications by linking directly to the right protocol. Signed-off-by: Eric Engestrom <eric@engestrom.ch> Reviewed-by: Brian Paul <brianp@vmware.com>

<h1>Gallium Post-processing</h1>
|
|
|
|
<p>
|
|
The Gallium drivers support user-defined image post-processing.
|
|
At the end of drawing a frame a post-processing filter can be applied to
|
|
the rendered image.
|
|
Example filters include morphological antialiasing and cell shading.
|
|
</p>
|
|
|
|
<p>
|
|
The filters can be toggled per-app via driconf, or per-session via the
|
|
corresponding environment variables.
|
|
</p>
|
|
|
|
<p>
|
|
Multiple filters can be used together.
|
|

<h2>PP environment variables</h2>
|
|
|
|
<ul>
|
|
<li>PP_DEBUG - If defined debug information will be printed to stderr.
|
|
</ul>
|
|
|
|
<h2>Current filters</h2>
|
|
|
|
<ul>
|
|
<li>pp_nored, pp_nogreen, pp_noblue - set to 1 to remove the corresponding color channel.
|
|
These are basic filters for easy testing of the PP queue.
|
|
<li>pp_jimenezmlaa, pp_jimenezmlaa_color -
|
|
<a href="https://www.iryokufx.com/mlaa/" target=_blank>Jimenez's MLAA</a>
|
|
is a morphological antialiasing filter.
|
|
The two versions use depth and color data, respectively.
|
|
Which works better depends on the app - depth will not blur text, but it will
|
|
miss transparent textures for example.
|
|
Set to a number from 2 to 32, roughly corresponding to quality.
|
|
Numbers higher than 8 see minimizing gains.
|
|
<li>pp_celshade - set to 1 to enable cell shading (a more complex color filter).
|
|
</ul>
