16 Graphics

1 Which one of these needs to be maintained in order to prevent an image from becoming distorted? (1)

A Z axis

B Aspect ratio

C Rotation

D Grouping

B Aspect ratio

2 Explain why vector graphics do not pixelate when they are enlarged. (3)

Vector graphics do not pixelate when enlarged because they are mathematically defined, allowing for precise recalculations and redrawings of the shapes and lines based on the new size.

3 Describe how layers can be used to create an image. (2)

Layers are transparent sheets in image editing software that allow artists to stack and manipulate different elements of an image separately. By arranging and adjusting these layers, artists can create complex compositions and make precise edits without affecting other parts of the image.

4 State the name of the small elements that make up a bitmap image. (1)

The small elements that make up a bitmap image are called pixels.

5 Give one drawback of using vector graphics to represent natural objects. (1)

One drawback of using vector graphics to represent natural objects is that they may lack the level of detail and texture that can be achieved with raster or pixel-based graphics.

6 State two ways of removing unwanted parts of an image. (2)

a) Cropping: It involves selecting a specific area of the image and removing everything outside of that selection.

b) Erasing/Deleting: This technique involves using an eraser tool or a selection tool to delete specific areas or objects from the image.
