Rasteriohjelmat

Rasteriohjelmat are software applications designed for the creation, manipulation, and analysis of raster graphics. Raster graphics, also known as bitmap graphics, are composed of a grid of individual pixels, each assigned a specific color. These programs are fundamental tools in digital art, graphic design, image editing, and scientific visualization.

Common functionalities of rasteriohjelmat include pixel-level editing, such as drawing, painting, and retouching. They allow users to adjust colors, brightness, contrast, and saturation, as well as apply filters and special effects. Many rasteriohjelmat also support layers, enabling non-destructive editing and complex image compositions. Image resizing, cropping, and format conversion are also standard features.

Popular examples of rasteriohjelmat range from professional-grade software like Adobe Photoshop, which offers a vast array of advanced tools for image manipulation and creation, to more accessible and often free alternatives such as GIMP (GNU Image Manipulation Program) and Krita. Simpler programs like Microsoft Paint are also considered rasteriohjelmat, catering to basic editing needs. The choice of rasteriohjelma often depends on the user's skill level, specific project requirements, and budget. These programs are essential for anyone working with digital images in a visual context.
