🧾 Introduction

In today’s digital world, images are everywhere — from websites and social media to printed materials and user interfaces. For a Computer Operator and Programming Assistant (COPA), understanding how images work and how to edit them is an essential skill. Whether it's resizing a logo, adjusting photo brightness, or creating a promotional banner, basic image editing is a common part of daily IT tasks.

This lesson will introduce you to the properties of digital images, image file formats, and the fundamentals of editing images using free and open-source tools like Paint.NET, GIMP, or even OpenOffice Draw.

🖼️ What is a Digital Image?

A digital image is a visual representation of something, created or stored on a computer. It is made up of pixels (short for "picture elements") arranged in a grid. Each pixel has a specific color value that together forms the complete image.

Digital images are mainly of two types:

1. Raster Images

• Composed of pixels.

• Common formats: JPG, PNG, GIF, BMP.

• Best for photos and complex visuals.

• Loses quality when scaled up (pixelation).

2. Vector Images

• Made of lines, curves, shapes defined mathematically.

• Common formats: SVG, EPS, AI.

• Best for logos, icons, illustrations.

• Can be resized without losing quality.

📷 Common Image File Formats

🧪 Basic Properties of Digital Images

When editing images, you need to understand their key properties:

📏 1. Resolution

• Measured in DPI (dots per inch) or PPI (pixels per inch).

• Higher resolution = more detail.

• Common screen resolution: 72 PPI; for print: 300 DPI.

📐 2. Dimensions

• Width × height in pixels.

• Example: 1920×1080 (Full HD), 1280×720 (HD).

🎨 3. Color Depth

• Number of colors an image can contain.

• Common depths: 8-bit (256 colors), 24-bit (16.7 million colors).

🧵 4. File Size

• Depends on resolution, format, and compression.

• Affects storage space and website loading times.

🪄 5. Transparency

• Some formats (PNG, GIF) support transparent backgrounds.

• Useful for logos and overlays.
