Does anyone know of any tools for manipulating TI's picture variables, or at least converting them to standard formats (e.g. bmp, png, ....) that support more than just the "normal" 83+/84+ size images? In particular, I'd like to be able to convert picture variables from my shiny new Voyage 200 without using TI-Connect, but I couldn't immediately find or remember a program that did this.

Most of the tools I found that do this sort of thing seem to mostly support the standard 83+/84+ screen and image format, which makes sense since few people have 68k calcs any more and probably even fewer the Voyage 200, but it makes me sad.

I poked around briefly on ticalc.org's /unix archive and didn't find anything obvious (well, that's not quite true. There was a GIMP plugin from 2003, but sadly it's pretty out-dated: compiled against the original libtifiles library and also against GTK 1 and an ancient version of gimp), so I figured I'd ask here.

(It's not so much that I'd refuse to use TI-Connect as much as that I'd like a cross-platform solution that would work on Linux too).

If there isn't at least a converter that supports the Voyage 200 screen size, I might work on one, assuming I ever have time to do that.

SourceCoder 3 is cross-platform (albeit a web app), and can do pretty extensive manipulation to and from monochrome 95x63-pixel pictures, CSE/CE Pictures, and and CSE/CE Images. It also supports the Casio Prizm's file formats and image size, but unfortunately, it does not support the 68k formats. Similarly, TokenIDE supports the z80 file formats, but not the 68k file formats.

A web app would definitely work for me, but yeah. :/

I'd ask if you'd consider adding support for the 68k formats someday, but I doubt such support would see much use and I know you have plenty of other things to work on, so...

I don't think a basic converter would be terribly difficult to write, so perhaps I'll give it a shot when I next have a free weekend.
