Any image processing suggestions?
For the current version of [link|http://www.atariage.com/forums/index.php?automodule=blog&blogid=148&|Medieval Mayhem] I manually converted a single dragon image to the format needed by my program. It took 4 hours to do the conversion, so I'd like to come up with a way to automate the process before I receive the 20(or so) frames of animation that I'll end up with. I plan to release the conversion program/script so other 2600 coders can use the technique.
The sprites on the Atari 2600 are limited to being 8 pixels wide, and there's only 2 of them. The routine I came up with to display [link|http://www.atariage.com/forums/index.php?automodule=blog&req=attach&id=1025|the Dragon](current test dragon) uses one sprite to draw the body, the other to draw the wings and body highlights. To get the size and detail, the sprites are drawn with double-wide pixels and each row can be shifted up to 7 normal sized pixels to the left/right of the prior row.
I think a unix script could be used to read in the images(each frame of animation in a seperate file) and output the data statements, but I'm not familiar with what tools are out there. I'm hoping the tools will work under OS X, but do not have any qualms about doing this on my Thinkpad under Kubuntu.
Here's some [link|http://www.atariage.com/forums/index.php?s=&showtopic=85667&view=findpost&p=1066360|animated images] I plan to test with. [link|http://www.atariage.com|Atari Age] is going to demo Medieval Mayhem with some other [link|http://www.atariage.com/features/shows/mgc2006_preview/|new and in development] games for the 2600 at the [link|http://www.midwestgamingclassic.com|Midwest Gaming Classic] on June 3rd and 4th, so it'd be great if I can get the [link|http://www.atariage.com/forums/index.php?automodule=blog&blogid=148&|test animation] frames converted this weekend so I have time to get the code updated to use the new images.
Thanks in advance.

Maybe XnView and/or NConvert?
I typically use PMView for my (simple) image processing needs, but have played with XnView a little. (It's got a nice web page generator.) It works with a lot of image formats. [link|http://perso.wanadoo.fr/pierre.g/xnview/enhome.html|XnView].
He also has a tool called [link|http://perso.wanadoo.fr/pierre.g/xnview/en_ncfeatures.html|NConvert] that may be perfect for your needs. I don't know if they handle the details of what you're trying to do though.
They're both freeware and run on just about anything.
HTH a bit.
Cheers,
Scott.

Not sure if those will work
the format is non-standard. I've added another replay with a sample of what I need to generate.
Thanks though.

Squeak has good image processing library
It reads and writes many formats and new ones aren't that hard to gin up. Worth a look.

Not what I was expecting
Downloaded it last night and was surprised to get a "squeek desktop" on my desktop. Should be an interesting weekend :-)

Find the class ImageReadWriter
and its subclasses.
Should get you going.

ended up using PHP
Squeak looks interesting, but it was taking too long to get into it for my schedule.
I don't have a "load your image" interface yet, but I do have it far enough along where I can use it by hard coding the image URLs to process:
