Raster Graphics:
Composition: Raster images are composed of pixels (picture elements). Each pixel represents a specific color, and when combined, they form an entire image.
File Format: Common raster image formats include JPEG and GIF.
Storage: Raster images use bitmaps to store information. A bitmap is essentially a collection of pixels.
Size and Resolution: The size of a raster file depends on the image dimensions. Larger images require more disk space. For example, a 640 x 480 image has information for 307,200 pixels, while a 3072 x 2048 image (from a 6.3 Megapixel camera) stores data for a whopping 6,291,456 pixels.
Scaling: Scaling down raster images is easy, but enlarging them results in pixelation or blurriness.
Use Case: Raster graphics are ideal for photographs due to their detailed representation.
Vector Graphics:
Composition: Vector graphics use mathematical curves and geometric shapes to create images. Instead of pixels, they rely on commands or mathematical statements.
File Format: Common vector formats include SVG, EPS, PDF, AI, and DXF.
Printing Quality: Vector graphics print crisply even when enlarged because they are based on mathematical formulas.
Scalability: Vector images can be scaled infinitely without losing quality.
Use Case: Vector graphics are best suited for logos, illustrations, and any content that needs to be resized without compromising clarity.
In summary, raster graphics are pixel-based and great for photographs, while vector graphics are mathematically defined and perfect for printing and scalable designs
