bittikarttakuvien

Bittikarttakuvien, a Finnish term, translates to "bitmap images" or "raster graphics" in English. These are digital images composed of a grid of individual colored dots, called pixels. Each pixel has a specific location and color value, and when viewed together, they form the complete image. Unlike vector graphics, which are defined by mathematical equations and can be scaled infinitely without losing quality, bitmap images have a fixed resolution.

When a bitmap image is enlarged beyond its original size, the pixels become larger and more visible, leading to a blocky or pixelated appearance. Common file formats for bitmap images include JPEG (or JPG), PNG, GIF, and BMP. These formats are widely used for photographs, digital paintings, and web graphics. The quality and file size of a bitmap image are directly related to its resolution (the number of pixels) and color depth (the number of bits used to represent each pixel's color). Editing bitmap images typically involves manipulating individual pixels or groups of pixels.
