B.3.2 Memory Needs of 2D Visualization Notes
Key Components of 2D Visualization
Pixels and Resolution
Pixels are the smallest units of a digital image.
The resolution of an image is defined by the number of pixels it contains, typically expressed as width × height (e.g., 1920 × 1080).
Note
The total number of pixels in an image determines the amount of memory required to store it.
Color Depth
Color depth refers to the number of bits used to represent the color of a single pixel.
Common color depths include:
8-bit: 256 colors (often used in grayscale images).
24-bit: 16.7 million colors (8 bits for each of the red, green, and blue channels).
32-bit: 24-bit color plus 8 bits for an alpha (transparency) channel.
Tip
Higher color depths provide more color accuracy but require more memory.
Image Formats
Bitmap (Raster) Images: Store color information for each pixel.
Examples: BMP, PNG, JPEG.
Vector Images: Use mathematical formulas to represent shapes and lines.

Introduction to 2D Visualization
2D visualization involves representing data or images in a two-dimensional space.
It is used in various applications, including graphics design, data visualization, and user interfaces.
Definition2D VisualizationThe process of creating and displaying images or data in a two-dimensional space.
ExampleCommon examples of 2D visualization include digital photos, charts, and game graphics.
AnalogyThink of 2D visualization like a digital canvas where you can draw and display images, similar to a piece of paper.
