[Pipmak-Devel] Image manipulation program

[Andrea V. <and...@gm...>]

SDL_image can only import image in vary formats, but at the moment we can
only save file as BMP.

I think should be usefull rotate images in authoring mode, this could be in
2 mode:

1) search some other library which permit to save image at least in GIF, JPG
and PNG
2) use an external program

the second one is the more simple to implements, and I found this one:

http://perso.orange.fr/pierre.g/xnview/en_nconvert.html

It is a command line tool and it's composed by only 1 file and it's
available for Win,Mac,Linux and others.
It 's a freeware for not commercial use (the sources aren't available).

I intend to add PNG saving support to our SDL_image as soon as I need it
for saving hotspot maps (code for that is around, the topic comes up
every now and then on the SDL mailing list).

Keep in mind that decompressing a JPEG image, rotating it, and
compressing it again is not a good idea. It is possible to losslessly
rotate JPEGs, but I don't know if there's a library suitable for our
purposes that does it.
