rasteritiedosta

Rasteritiedosto is a digital file format used to store raster graphics, which are images composed of a grid of pixels. Unlike vector graphics, which use mathematical equations to define shapes, raster graphics store information about each individual pixel. This format is widely used in various applications, including graphic design, photography, and web development.

Rasteritiedosto files can be saved in several formats, each with its own advantages and disadvantages. Common raster file formats include JPEG, PNG, GIF, and BMP. JPEG is popular for photographs due to its efficient compression, which reduces file size while maintaining image quality. PNG is favored for graphics and images with transparency, as it supports lossless compression and alpha channels. GIF is often used for simple animations and images with a limited color palette. BMP is a simple and uncompressed format that is widely supported but results in larger file sizes.

The choice of rasteritiedosto format depends on the specific requirements of the project, such as the need for compression, transparency, or animation. Understanding the characteristics of each format is essential for selecting the appropriate one for a given task.
