#8474 closed patch (outdated)

2xPM scaler

Reported by: fingolfin Owned by:
Priority: normal Component: Graphics: Scalers
Keywords: Cc:


I was curious after reading feature request #1315759 and looked at
the 2xPM and 2xPM_LQ scalers (original site: <http://>).

Thanks to our flexible scaler infrastructure ;-), it was easy to
experimentally include these two scalers, see the attached file (copy
the .cpp files into common/scaler/, after that apply the patch).

Note that the code hasn't been optimized nor cleaned up according
to our coding conventions, since it was meant as a quick hack only
and since I don't even know if we actually want to include these
changes or not... It would be trivial to change that, though.

Hehe I made the same thing some time ago, I will upload my
patchfile too it uses out coding converntions.
Did not looked at your gfx output until now but I had some
problems with a direct copy so I changed some things a bit.
Dunno if my patchfile applies correctly since it is some
time old.

I will take a look at yours later.

I have modified and incorporated Lordhoto's patch into a scaler plugin on my github repository ( So this will probably eventually get merged with the rest of my GSoC project.

I suggest this be closed.

As suggested by singron, this has been added in his GSoC pull request here:

Thus this patch is now obsolete, and will be eventually merged together with the rest of singron's changes.

Closing as out of date, and changing the group to GSoC
