ITPEC FE Morning April 2021 Question 24

Vector graphics built from mathematically defined lines and curves — drawing software stores shapes as geometry, not as pixels.

In drawing software every object is a line, curve or shape described by its coordinates and properties. Because the picture is kept as geometry, an object can be moved, scaled, rotated or combined with others without losing quality, and the file stays small.

Answer (d)

Why not others:

• •(a) — painting with the mouse as a brush and saving a bitmap describes paint software, which works on pixels (raster graphics)
• •(b) — arranging text, images, video and sound into scenario-based content describes authoring software
• •(c) — generating a movie by gradually changing between still images describes animation software, such as morphing or tweening tools

Key rule: Drawing software means vector graphics (geometry that scales cleanly); paint software means bitmap graphics (pixels that blur when enlarged).
