Rasterisisällön

Rasterisisällön, often translated as raster content or raster graphics, refers to digital images that are composed of a grid of individual pixels. Each pixel is a tiny square or dot that has a specific color value. When viewed together, these pixels form a complete image. This is in contrast to vector graphics, which use mathematical equations to define lines, curves, and shapes, allowing them to be scaled infinitely without losing quality.

The quality of rasterisisällön is determined by its resolution, which is the number of pixels that make up the image. Higher resolution images contain more pixels and therefore appear sharper and more detailed, especially when enlarged. Common file formats for rasterisisällön include JPEG, PNG, GIF, and TIFF. These formats are widely used for photographs, web graphics, and digital art. Editing rasterisisällön typically involves manipulating individual pixels or groups of pixels. Software like Adobe Photoshop and GIMP are commonly used for this purpose. While raster graphics are versatile, they can become pixelated or blurry when scaled up beyond their original resolution.
