Study Notes

Vector Graphics Overview

Vector graphics consist of images stored as a list of attributes.
Unique characteristics: images are defined by geometric shapes rather than pixels.

Key Vocabulary

Vector graphic: an image format based on mathematical equations.
Attribute: defining characteristics of an object, such as size and color.
Object: the shapes that make up a vector graphic.
Layer: a method to manage the stacking of objects to create depth.
Scalable: ability to resize an image without losing quality.

Structure of Vector Graphics

Images are formed by objects, which include attributes such as:
- Height and width
- X and Y coordinates for positioning
- Outline and fill color
- Line width
The shape is represented by points connected by lines, exemplified by the corner coordinates of a triangle.

Editing Vector Graphics

Objects can be edited independently, allowing for adjustments like resizing and color changes.
Features:
- Objects can be clicked and dragged to resize.
- Formatting options provide capabilities for altering color and line attributes.
- Layering allows combination of objects for more intricate designs.

Advantages of Vector Graphics

Scalable without loss of quality, making them ideal for various sizes.
Generally small file sizes due to memory-efficient storage from attributes.

Common Vector Graphic Formats

.eps: Encapsulated PostScript File.
.svg: Scalable Vector Graphics File.

Creating Vector Graphics

Vector-style graphics can be created using:
- 'Shapes' tool in Word's 'Insert' tab.
- 'Drawing' tools in Google Docs.

Activities and Practice

Activities include written exercises and worksheets focusing on vector graphics concepts.

Critical Thinking

Consider scenarios where vector graphics are preferable over bitmap images for improved clarity and scalability.

Assessment Criteria

Grade 1-3: Identify what defines an image made up of objects.
Grade 4-7: Explain how the shape of an object is stored in vector graphics.
Grade 8-9: Name a type of vector graphic file and discuss scalability.
