What is Graphics?
Graphics refers to visual images or designs displayed on a screen or printed on paper. In computer studies, graphics means any picture, shape, drawing, or text you create with the help of a computer. These graphics can be used in posters, logos, magazines, charts, and animations.
Types of Graphics
There are two main types of computer graphics: Raster (Bitmap) and Vector graphics.
Raster (Bitmap) Graphics
- Structure: Made up of tiny dots (pixels) arranged in rows and columns.
- Best used for: Photographs and complex color images.
- Common formats: JPG, PNG, GIF, BMP.
- Limitation: When enlarged, the picture becomes blurry or pixelated.
Vector Graphics
- Structure: Made up of points, lines, and curves called paths.
- Best used for: Logos, signs, and illustrations.
- Common formats: SVG, EPS, PDF, and CDR (CorelDRAW format).
- Advantage: You can resize them without losing quality.
