I just pushed an update which implements a PNG encoder. It is
implemented in the Image class as a write method. If you have a
raw buffer, and want to encode it, you can do something like this:
ubyte data = some data;
Image img = new Img!(Px.R8G8B8)(width, height, data);
It uses adaptive filtering, and should work with the pixel
formats supported by the image class (except for the 16 bit ones
I've just realised). I've only tested it on images that I have
previously loaded in however.
Stewart, I used your makepng.d as a template for this, can I add
you to the author list?
Also, if preferred, I can keep the master branch as a single
merged module, just let me know.
