Scaling not great?

[francisdb]

This is Baywatch:

192x64 rendered to 128*32

• Could scaling be improved? Is nearest neighbor in use?
• I wonder if stretching to the full space would be a good idea?

@francisdb this doesn't seem to be libzedmd's own downscaling, but the one of DMDext.
Which versions are you using?

[mkalkbrenner]

But feel free to contribute an improved downscaling algorithm to libserum. I would appreciate that!

[mkalkbrenner]

This is how it looks like using the latest versions:

I'm using vpinball standalone with built in flex DMD port. Feel free to close this if not related to libzedmd.

At the moment, the scaling is done by libzedmd or ZeDMD itself.
But together with @jsm174 we consider to move the scaling into a common DMD lib.
So we should leave this issue open for now.

it seems that the current scaling works better for colorized ROMs.

moved to vpinball/libdmdutil#2

[francisdb]

Seems that libdmdutil is not doing any scaling

I started working on libdmdutil
