digitalmars.D.announce - Tiny Jpeg Decoder
- Tomas Lindquist Olsen (14/14) Apr 03 2007 Hi all,
- Bill Baxter (9/30) Apr 03 2007 Sweet. Three files and minimal dependencies! Know of any other tiny
- Gregor Richards (3/40) Apr 03 2007 Search the newsgroups, somebody posted a port of lodepng.
- Bill Baxter (6/21) Apr 03 2007 Thanks. It was Lutger.

- BCS (2/3) Apr 04 2007 If you want, I can let you put it up on scapple well.
- Bill Baxter (11/12) Apr 04 2007 Hmm. I think the one in GLD handles 8-bit TGA gray maps too. Maybe
- Lutger (2/23) Apr 05 2007 Very nice thank you!
Hi all, I've ported a small Jpeg decoder from C to D and decided I'll let you all know about it. I needed it for a small image loading library I've been working on. This will probably be released at some point as well, but until then here's the jpeg decoding part. BCS has kindly allowed me to put it in scrapple, so getting a copy should be a familiar process to most D users. [1] You can check out the scrapple site at: http://dsource.org/projects/scrapple I made a small wiki page with a usage example, The original C source code can be found at: http://www.saillard.org/programs_and_patches/tinyjpegdecoder/ Hope it's useful for someone. - Tomas Lindquist Olsen [1]: http://dsource.org/projects/scrapple/browser/trunk/tinyjpeg

Three files and minimal dependencies! Know of any other tiny image format decoders? Specifically a decoder-only "tinypng" would be nice to have. Phobos has std.zip already so it should be possible to write a very tiny decoder. I guess most BMP and TGA decoders are tiny to begin with. GLD has a nice little TGA decoder that's 384 lines. Might be nice to extract that into a little scrapple lib too. --bb

I have coded a TGA decoder that loads compressed and uncompressed TGA files. 24 or 32 bit. It's super-tiny (~100 lines of code). If you could use it in your _open sourced_ project, I'd be glad to contribute.

And I don't think it's encumbered by any "open source only" license (GLFW, where it was ported from is Zlib). So... I should get off my duff and make a stand-alone port of it for scrapple. Anyway, I really like the idea of assembling a tiny, dependency-free, bare-bones collection of image loaders. Next step would be to give these PNG/JPEG/TGA loaders a consistent API for loading and such. --bb
