A rasterizer takes shapes and produces coverage values for the pixels which represent how much each pixel is covered by the shape. These are alpha values and each pixel is associated with its own alpha value. Alpha values can be thought of as part of a pixel's color, they indicate the transparency of the pixel. Alpha values range from 0.0 for no coverage to 1.0 for full coverage. LViewPro - Windows shareware which handles a variety of file formats and allows for editing Rendering is taking taking shapes, text and images and figuring what colors the pixels should be on screen or on the printer.
Graphics primitives are the shapes, text and images and screens and printers are the output devices.
A rendering engine performs the work of displaying graphics primitives on output devices. In 2D the Graphics2D class is the rendering engine.
