bitmapowe

Bitmapowe is an adjective derived from bitmap, used in Polish to describe things related to bitmaps or raster images. In computing, a bitmap image is a raster graphic defined by a grid of pixels, with each pixel carrying color information. A bitmap image is typically specified by its width, height and color depth. Bitmapowe graphics are resolution-dependent; enlarging an image can cause pixelation unless the image is redrawn at a higher resolution. This contrasts with vector graphics, which describe shapes and can be scaled without quality loss.

Common bitmap formats include BMP, PNG, JPEG, GIF and TIFF. Bitmap images can use lossless or lossy compression; PNG and TIFF often employ lossless compression, while JPEG uses lossy compression. Color depth can vary from monochrome to millions of colors; some formats support transparency via an alpha channel. Bitmaps require storage proportional to resolution, color depth and compression.

Bitmapowe fonts, or bitmap fonts, are sets of pre-rendered glyphs stored as bitmaps for specific sizes. They render quickly and with predictable spacing but do not scale smoothly, which led to the adoption of scalable vector fonts in modern systems. Bitmap fonts are still used in embedded systems and some legacy interfaces where performance and memory predictability are important.

Historically, bitmaps were among the first widely used methods for storing and displaying digital images. Today, bitmap images are ubiquitous in digital photography, web graphics, user interface elements, textures in computer games, and many image storage formats.
