Rasterikuvat

Rasterikuvat, also known as raster graphics or bitmap images, are a type of digital image that is composed of a grid of pixels, each representing a single point in the image. Unlike vector graphics, which use mathematical equations to define shapes, raster images store information about the color and intensity of each pixel. This makes raster images well-suited for representing complex images with subtle color variations and textures.

Raster images are commonly used in various applications, including photography, digital art, and web design. They can be created using a variety of software tools, such as Adobe Photoshop, GIMP, and Paint.NET. Raster images are typically stored in file formats that support pixel-based data, such as JPEG, PNG, and BMP.

One of the main advantages of raster images is their ability to capture fine details and textures. However, they also have some limitations. Raster images can become pixelated or lose quality when scaled up or down, a phenomenon known as aliasing. Additionally, raster images can be larger in file size compared to vector images, especially for high-resolution images.

In summary, rasterikuvat are a fundamental type of digital image that uses a grid of pixels to represent visual information. They are widely used in various applications and offer the ability to capture fine details and textures. However, they also have limitations related to scaling and file size.
