[Plib-devel] User defined texture formats

[Trent G. <tm...@cy...>]

I think SSG needs to have some hooks to allow user defined image
formats, or support more formats natively. Native support for complex
formats like JPEG or PNG can only be done by duplicating a lot of
code, since Steve doesn't want any extra library dependencies.

Would this be useful to anyone else? Does anyone have any ideas on how
we could allow user defined image formats? I'm a C programmer, so the
first thing I think of is an array of function pointers and a function
to register new formats, something like:

int register(char *ext, void (*func)(char *fname, char **data, int *w,
  int *h, int *z)

Then have ssgImageLoader::loadTexture look for a user function if an
internal one doesn't exist. But maybe there is a better way in C++?

The reason I need this is so I can call functions like ssgLoadAC,
where the models have textures in them in formats that aren't
supported by SSG. Converting my textures to BMP or SGI is not really
an option, because they go from about 5 megs (jpg) to over 60 megs.
