Hi I notice that Imago is not really getting much discussion on the imago-devel mail list. I'm curious if previous users are now using a better library? I've been using it and for what I need it suits my modest requirements with the exception of write-pnm not supporting indexed images. I'm just checking if it's worth my effort to do the work adding support or whether I'd be better off throwing my support behind a more active project?

Hello Leigh,

I am not aware of better or more active projects of this type, but there may be, you might want to ask on comp.lang.lisp. It is true that imago-devel is pretty calm (to say the least), I do not know whether it is because not many people use the library or because it is so great that nothing remains to be said (although the former seems more likely)... :) Anyway, I would be glad to know about any comments or criticism you may have. Julian Squires recently checked in a few modifications, and I may have some time to hack on it soon if needed.
Note: I think indexed images are not supported by the PNM format. If this is true but you want to save images, you may want to replace the corresponding write-pnm-to-stream method with one that converts the indexed image to an RGB image then calls write-pnm with it. If I am wrong and PNM does support indexed images, then please let us know so we can add the code (or you can of course send the code directly).
Cheers,

Hello Leigh,
Thanks for the update. I'll check things out, but I agree, the Lisp community is pretty small, so it's not surprising things can be pretty quiet.

Yes my plan was to convert to an RGB image, but I thought I may as well do the conversion on the fly within write-pnm-to-stream specialised on indexed-images method to save building a full image, it's just a look up of the colour map table.
