Rasteriaineiston

Rasteriaineiston, also known as raster graphics, is a method of representing digital images using a grid of pixels. Each pixel in a raster image is a small square that contains color information. The resolution of a raster image is determined by the number of pixels it contains, with higher resolutions resulting in sharper images. Raster graphics are widely used in various applications, including digital photography, video games, and web design.

One of the main advantages of raster graphics is their ability to represent complex images with a high degree of detail. However, they also have some limitations. Raster images can become pixelated or blurry when scaled up, and they can lose quality when compressed. Additionally, raster graphics are not easily editable, as changing the size or shape of an image can result in a loss of detail.

Raster graphics are typically stored in file formats such as JPEG, PNG, and GIF. Each format has its own advantages and disadvantages, with JPEG being commonly used for photographs due to its ability to compress images without significant loss of quality, and PNG being preferred for images that require transparency or lossless compression.

In contrast to raster graphics, vector graphics use mathematical equations to define shapes and lines, allowing for infinite scalability without loss of quality. However, vector graphics are not as well-suited for representing complex images with intricate details. The choice between raster and vector graphics depends on the specific requirements of the project at hand.
