C++ fast library for drawing 2d with transparency

Question

I'am looking for fast library too make some 2d drawings. I need only to draw polygons, change transparency of them. I don't want to display result in any window, saving to file will be enoght (faster = better) - I want to learn my algorithm how to draw shapes so i need only methods like "drawPolygon" and "getPixel" to compare results.

How about good old OpenGL? Or perhaps D3D if you're on Windows. — Cornstalks, Oct 10 '12 at 06:54

OpenCV would also be a valid choice for doing something basic like this.

It doesn't properly support transparency: it has RGBA images, but doesn't support alpha blending. – ansgri Apr 01 '16 at 16:27

The GD library is ideal for drawing shapes onto bitmaps.
