The font utility uses windows and is menu-driven. The utility uses a library of fonts that can be selected and modified. This allows you to start editing a character that looks similar to what you want, rather than using the slower method of drawing a character. In raster editing, a display image is composed of an array of pixels arranged in rows and columns. In vector editing, display images are generated from coordinate data.
Raster editing uses a lattice-like grid.
Each grid unit contains a pixel. A pixel is a picture element, or dot, on the screen. Together these pixels form a character. By turning these pixels on and off and setting the pixels to different sizes, you can create a new character or slightly alter an existing character. Vector editing uses a coordinate grid.
