The library makes full use out of D's templates and
metaprogramming. The internal storage mechanism is entirely
configurable from almost every endpoint. File headers are
directly loaded into structs defining them, removing most of
the difficulties in reading them according to spec. The image
type and loading API is entirely extensible, making extra image
formats entirely self-contained.
Currently only loading and saving of simple BMP images is
supported, with convolution and Gaussian Blur filters and flip
transformations. Its still early in development, but I'd love
to get some feedback on it.
Example:
---
import daffodil;
import daffodil.filter;
import daffodil.transform;
void main() {
auto image = load!32("daffodil.bmp");
image.gaussianBlurred(1.4).save("blurry_daffodil.bmp");
image.flipped!"y".save("upside_down_daffodil.bmp");
}

The license is MIT, so feel free to do whatever you want with
the code. Issues and pull requests are of course welcome ;)
Alongside I've also written (an admittedly hacky) sphinx
(http://www.sphinx-doc.org/en/stable/) extension that provides
a domain and autodocumenter for D, using libdparse and pyd.
Hi there. Took a quick look at the source and it seems really
nice! I like your idea of extensibility for color conversion.
Also, image I/O seems to be set up quite nicely for a starting
point. Although I have to comment that bit depth shouldn't be a
template argument, in my opinion. When loading images, bit depth
should be determined in the runtime, depending on the image you'd
be loading at the moment. Or am I wrong? - do you have some other
way of handing this case?
Also wanted to let you know I've been working on a similar
library for some time now [1].
Hope we could merge some modules and learn from each other, and
not have multiple different implementations of the same stuff.
Please let me know if your interested.
