The hardest part was to find one that could work with D easily.

I guess now Imageformats (and my own dimage) can have GIF and TIFF file support.

That is really great.

Side question, did you considered to rewrite a C library (e.g. https://github.com/vapier/liblzw) to D?

Kind regards

Probably it would be easier than the times I tried to rewrite much more complex C++ libraries/apps to D, however I thought it would be sufficient enough to just write a binding for a library.

liblzw's biggest issue was that
a) It's output only.
b) It directly accesses files, which makes buffer reads and writes impossible to the point you have to pass the file path to a function. Using temp files would probably solve this problem, but it's extremely kludgy when you could just use memory buffers. Not to mention the wear on modern SSDs.

One of my plans was to port ncompress to D as a library with memory buffer reads/writes enabled, but before that I asked around and found libncompress, which is that for C. MAybe I'll add some higher level API for it in the fashion of std.zlib, only more stable.
