You might consider using SDL and SDL_image:
https://libsdl.org/download-2.0.php
https://www.libsdl.org/projects/SDL_image/
D bindings for both are available here:
https://code.dlang.org/packages/bindbc-sdl
You don't actually *need* SDL_image, as core SDL can load images
in the BITMAP format, and you can then use the API to create
transparency from a specific color. But if you want to load PNG
files with alpha, you'll want SDL_image.
There are numerous tutorials online for SDL, though if you're
searching, make sure to look for SDL 2 tutorials and ignore
anything for SDL 1.x.
The tutorials will all be in either C or C++, but the SDL API
using the D bindings is the same. The Lazy Foo tutorials are
often recommended:
https://lazyfoo.net/tutorials/SDL/
But again, these are C++, so you have to consider the differences
in D and C++ when porting the code over. For example, he uses
class destructors to free resources. Do that in D and you'll run
into trouble. So just ignore how he structures his programs and
focus on the main concepts of using SDL: how to acquire/release
resources, how to render, etc. You can adapt that to any
architecture you want. There's no need for classes at all, for
example.
Some tutorials out there will show you how to use SDL with
OpenGL. Please ignore those. SDL's 2D Rendering API is what you
want when you're learning, so focus on tutorials tat show you how
to use it.
The SDL Wiki has API documentation:
