Yes but I use mostly terminal.d and others.

On the other hand I use to code games too using SDL and OpenGL.

I know for example in OpenGL you can do: 
glEnable(GL_ALPHA_TEST); to enable alpha channel and set 
transparency.

Thanks, but I don't know how that will fit in my code. I will 
show up a code snippet and you tell me how I can use your idea in 
it, okay?

import arsd.image, arsd.simpledisplay;

void main()
{
    auto memImgShip = loadImageFromFile("ship.png"), 
memImgBackground = loadImageFromFile("background.png");
    auto imgShip = Image.fromMemoryImage(memImgShip), 
imgBackground = Image.fromMemoryImage(memImgBackground);
    auto window = new SimpleWindow;
    window.eventLoop(10,
    {
        auto painter = window.draw;
        painter.drawImage(Point(0, 0), imgBackground);
        painter.drawImage(Point(100, 100), imgShip);
    });
}

Here it is, how do I make the ship have a transparent background?
