Working on a library: request for code review

[Mike via Digitalmars-d-learn]

I can shed some light on my, beginners, point of view and the 
rationale behind this tiny library.

I want to create a bar/matrix-code generator (QR, DataMatrix 
etc.). I really like graphics-related subjects and I thought this 
would be a good start in D.

Coming from Java island and having experience in Go I expected to 
find some basic imaging functionalities in the standard library: 
not necessary support for all image formats, but at least some 
bitmap i/o and data model (Pixel, Image, Filter ...).

I found none of that :-(

IMHO (one of the) pain(s) of C++ is that the stdlib is far behind 
what a modern developer would consider "elementary".

But I expected something from D, because Phobos is already more 
than C++'s stdlib is: Phobos has e.g. digests. IMO digests are 
not (as) necessary for a standard library as, say, a qsort is. So 
if there are digests, why not imaging?

Either way, D is really nice and if I can help, I will :-) So far 
- the TGA lib.

Best,
Mike
