Title: OAReduce (0.0001 bat version)
Post by: fromhell on January 29, 2009, 01:37:47 am
I was bored once, tried to make an OA reducing script.
Half-ing the textures (ALL OF THEM including models and gfx) and ogging sounds reduces OA to 140MB.

REQUIRED:
- 7zip (redundant!)
- Infozip
- Oggenc (I used oggenc2 from some build out there which was sse2 optimized)
- Imagemagick

BUGS:
- Imagemagick is required and imagemagick sucks (borks the alphas, bloated (Requires at least 25-50mb))

This is good, do you plan to use the result for some next release, or is it just a test to get an idea of what is possible ?
note: I used an ogg song on a map, it took some time to load when looping, so I suppose low space is not always better.

I done this and still have the files but it was for 0.7.1

Took me 10 mins using a program called thumbsplus. I reduced all 512x512 to 256x256 and 256x256 to 128x128.

I think I left the jpg's and all the non-square images (since I thought they might be fixed size for parts of the maps)

Is there a reason for using imagemagik etc?

fast and works in commandline/tty
you can also use python image library :P

Yea good for people who are familiar with it and use it often. For me I use the tard alternative as it's most efficient, waste of time to learn something I'm hardly going to use. Takes me a few mins to scan and batch resize an entire tree of image files.

I done the 081 pak4-textures.pk3 and the file size is 33.6mb.  I did try one oa map and didnt notice any problems, I use 800 res so unlikely to notice any loss of quality - performance is hard to guage... I wasnt getting completely stable 125 but as others have said, this could well be map related.

I will upload this file and do the rest then post the links to the paks. If this is a waste of time then please let me know as i do not have a mega-fast connection.

also change all non-transparent TGAs to JPEGs with hi-compression

I'm not that advanced to filter the transprency ones yet :D I could do a full conversion of tga to jpg and they would be all be contained in orig folders.. dont know if that is any use

I have also coverted every wav file to ogg.. but would that work in game or would the source need to be modified for that?

These are the coverted files:

Imagemagick is a nice tool, specially when you're an opensource addict and have no tool to manipulate numerous images at a time (I don't know to translate "traitement par lot", which GIMP doesn't do). It's also handy when using shell script, for expl, you can easily make a script to build an HTML (or BBCode...) gallery with the images you just cropped/resized/converted/... . You don't have to learn everything, only the few parameters you need ;-) so it doesn't take that much time, and once you're aware of what that tool can do it can save you some time ; but I think it's mostly for linux users who are already a bit trained with shell scripts. I never really took the pain to learn windows scripting ... ;)

Batch process :D

You can get lots of php progs (i find them on hotscripts.com) that do the same stuff, only php is using imagemagik to control the conversions. I downloaded PHP Album for my map thumbs, its great.. just shove all the images in one folder and you can process/display them in which format you want.

I wouldnt know how to do it in photoshop or gimp, but i can easily do sounds using 'batch convertor' in soundforge. Thats what I used to modify my risky oa sounds.
