(a)(i) Define computer graphics.

Computer graphics is the branch of computing concerned with creating, storing, editing and displaying pictures, images, drawings and other visual content using a computer. It covers both the pictures produced (such as diagrams, charts and animations) and the techniques and software used to generate and manipulate them.

(a)(ii) Two applications of computer graphics in advertising:

• Designing posters, banners, flyers and billboards for products.
• Producing logos, product packaging designs and animated television or online adverts.

(b) One use of each graphics tool:

• (i) Interactive Fill Tool: used to apply and adjust a fill (colour, gradient or pattern) inside an object interactively by dragging directly on the object.
• (ii) Texture Fill Tool: used to fill an object with a textured, natural-looking pattern (such as clouds, water, marble or rock) instead of a plain colour.
• (iii) Envelope Tool: used to reshape or distort an object or text by dragging its surrounding frame (envelope) so the object bends to a new shape.
• (iv) Extrude Tool: used to give a flat object a three-dimensional (3D) appearance by adding depth/perspective to it.

(c) Name one Fill Tool needed to:

• (i) create a background faded from light blue to white: the Fountain Fill (Gradient) Tool.
• (ii) fill an object with two colours that blend from one to another: the Fountain Fill (Gradient) Tool (a two-colour linear/radial gradient).
