TYPES OF GRAPHICS

 

• Raster Graphics:
  Definition: Images are composed of a grid of individual pixels, each with its own color and intensity.
  Characteristics:
  Resolution-dependent: The more pixels, the higher the resolution, and the better the quality. 
  Well-suited for realistic images, photographs, and images with complex shading and color variations. 
  EXAMPLES: Digital photographs, images on the internet, and most images displayed on computer screens. 
  
  
  
  
  
Vector Graphics:
Definition: Images are defined by mathematical equations that describe lines, curves, and shapes.
Characteristics:
Resolution-independent: Scalable without losing quality. 
Ideal for images with clear lines, logos, illustrations, and diagrams. 
EXAMPLE: Vector graphics can be found in graphic design software like Adobe Illustrator and CorelDRAW. 

Here's a table summarizing the key differences:

Feature	Raster	Vector
Representation	Grid of pixels	Mathematical equations (lines, curves, shapes)
Scalability	Not scalable, loses quality when resized	Highly scalable, retains quality
Use Cases	Photographs, complex images, detailed graphics	Logos, illustrations, drawings, scalable designs
File Formats	JPEG, PNG, GIF, BMP, TIFF	SVG, AI, PDF, EPS, WMF
Example	High-quality photo, photo edited in Photoshop	Logo, drawing in Illustrator

Raster Images:

Pixel-based:
Raster images are made up of tiny squares called pixels, each with a specific color value. 
Resolution-dependent:
The quality of a raster image is determined by the number of pixels it contains. Increasing the size of a raster image without adding more pixels results in a loss of quality and pixelation. 
Ideal for:
Raster images are well-suited for photographs, complex images with soft colors, and images where fine details and shading are important. 
Common file formats:
JPEG, PNG, GIF, BMP, TIFF. 

Vector Images:

Mathematical equations:
Vector images are created using mathematical formulas to define lines, curves, and shapes. 
Scalable:
Vector images can be scaled to any size without losing quality because they are based on mathematical equations rather than pixels. 
Ideal for:
Vector images are best used for logos, illustrations, drawings, and designs that need to be scalable without losing quality. 
Common file formats:
SVG, AI, PDF, EPS, WMF.
