Scan conversion is the process of:

converting a geometric primitive into the set of pixels that best represent it on a raster display

converting an analog image into digital form by a scanner

filling a polygon with colour only

converting 3D coordinates into 2D coordinates

What does scan conversion do with the selected pixels?

Stores them as vector commands in a display list

Sends them directly to the keyboard

Which of these are examples of scan-conversion algorithms?

Short answer

Scan conversion (rasterization) is the process of converting geometric primitives like lines and circles into a set of pixels in the frame buffer. It determines which pixels best approximate the ideal shape on a raster display.

What is scan conversion?

Scan conversion (rasterization) is the process of converting a geometric primitive (line, circle, ellipse, polygon, text) specified by mathematical equations or end points into the set of pixels on the raster display that best represent it. It selects the pixel positions and sets their intensity in the frame buffer. Examples are the DDA and Bresenham's line algorithms.
