Raster Graphics

Raster graphics, also known as bitmap graphics, are digital images composed of a grid of pixels, where each pixel contains color information. They are resolution-dependent, meaning image quality degrades when scaled up, as pixels become visible. Common file formats include JPEG, PNG, GIF, and BMP, widely used for photographs, web images, and digital art.

Also known as: Bitmap Graphics, Pixel Graphics, Raster Images, Rasterization, Raster

Why learn Raster Graphics?

Developers should learn raster graphics for handling image processing, web development, and UI/UX design, as they are essential for realistic visuals like photos and complex textures. Use cases include optimizing images for web performance, implementing image editing features in apps, and working with camera outputs in mobile or desktop applications.
