rasterimuotoiset

Rasterimuotoiset refers to a type of digital image representation. In this format, an image is composed of a grid of individual colored squares or dots, known as pixels. Each pixel has a specific color value assigned to it. When viewed together, these pixels create the illusion of a continuous image. The resolution of a raster image is determined by the number of pixels it contains, both in width and height. A higher resolution means more pixels, which generally results in a sharper and more detailed image, but also a larger file size. Common examples of raster image file formats include JPEG, PNG, and GIF. Raster graphics are well-suited for representing photographs and complex, photorealistic images due to their ability to capture subtle color gradients and details. However, when raster images are scaled up beyond their original resolution, the individual pixels become visible, leading to a blocky or pixelated appearance. This characteristic makes them less ideal for designs that require sharp lines and text, where vector graphics might be a better choice.
