Bitmapbased
Bitmapbased is an adjective used in computing to describe resources, methods, or systems that rely on bitmaps—arrays of pixels stored as values in memory. In this sense, a bitmapbased approach uses raster representations rather than scalable vector forms. The term is often used to describe fonts, images, and indices that are anchored to fixed pixel grids.
In fonts, bitmapbased fonts store each glyph as a bitmap image at one or more discrete sizes.
In data management, bitmapbased indexing uses bitmaps to represent the presence of attribute values across records.
Advances include compressed bitmap formats and hybrid systems that switch between bitmapbased and vector representations depending
