PyMapConv

[Beherith]

A full python implementation of mapconv. With GUI. Also supports full decompilation and recompilation.
The only thing it doesnt do is lossy tiling smt compression, it does do lossless though.
On 32bit machines it compiles 32x32 maps easily.
Very verbose error checking.

Spaghetti and meatballs code.

Also supports 16bit png heightmaps.

EDIT: Now includes a windows binary so that python is no longer needed (prebuilt pymapconv.exe, make sure to keep all the other files next to it though!)

Very cool thing. Thanks!

Interesting. Didn't try in detail but on Linux I needed to change one of the imports to:

Code: Select all

from PIL import Image

Beherith only does awesome

[Kloot]

How many mapconvs does this make now?

[Beherith]

It started off as a decompiler, but I figured its not much extra to do the compilation once the framework is in place. I think this is number 5 in the list btw ;D

[Forboding Angel]

This pretty much blows all other mapconvs into instant obsolescence. Thanks Behe, this is really cool.

ImportError: No module named Image

Windows..old python install..cryptic error msg be cryptic.. open file, be warned - spaghettis..

[Beherith]

Picasso, it needs PIL installed, and python 2.7+ preferably. And pasghetti.

Nice one, if it is as straightforward to install and use as it seems then this will be interesting.

I wonder how well it performs compared to SME, gajop mentioned something about optimizations, i have no idea what he means tough.

[Beherith]

WRT optimization: this compiler only does lossless tiling compression, and does not do lossy tiling compression. This can result in larger map files. Otherwise performance to SME is identical.

[gajop]

...SME, gajop mentioned something about optimizations...

I was talking about lossy optimization.
We were discussing whether or not an official compiler distributed with spring (and maybe even in-engine) should exist. One of the things I said was that if implementing optimization is non-trivial, and could be done in many ways, leaving room for unofficial implementations would be preferred.
Some people mentioned that we had too many existing compilers, most being unreliable.
This was before behe released this, incrementing the $map_compiler_count.

whats your performance like?
For instance this 10kx10k photo of burning man

my 4th gen Corei7 processes this file into an smt in 40 seconds and uses under a gig of ram.. how does that compare to pymapconv?

[Beherith]

Its pretty fast, but the bulk of the load is compressing the texture to dds with nvdxt. With the highest quality settings that are enabled by default, it can take a minute or two. In quick mode its under a minute.

[Forboding Angel]

After some very annoying figuring out wtf... I found out the following.

Requires python 2.7 - (no surprise there) 32bit (color me surprised) https://www.python.org/downloads/
Requires PIL - (Python Image Library) (Why isn't this mentioned in the op?) http://www.pythonware.com/products/pil/
Requires PyQt4 - https://riverbankcomputing.com/software/pyqt/download

Using on windows when you don't have python already installed can be kind of annoying, but it's not too bad.

I found it interesting that it uses TIFF as an intermediary. This is good and should yield higher quality results.

Craps itself (not really, it just won't go any further) if you feed it an rgba heightmap (with only greyscale in it).

I found this more than a little annoying:

[Beherith]

Fixed, thx

[Beherith]

Added file open dialog buttons so you can quickly select your files for compilation without having to type them in. Also fixed compilation under linux, and headless compilation works as well if you specify command line arguments.

[TurBoss]

thank you

[TurBoss]

I have compiled pyMapConv to exe for windows users

Could you post it onto SpringFiles instead? Or attach to your post as a file.
