Different file systems manage space allocation with one or more block oriented bitmaps; in XFS, these structures are replaced with an extent oriented structure consisting of a pair of B+ trees for each file system allocation group. Source: Internet
Converting outlines requires filling them in; converting to bitmaps is not trivial, because bitmaps often don't have sufficient resolution to avoid "stairstepping" ("aliasing"), especially with smaller visible character sizes. Source: Internet
The fonts displayed by Links are not derived from the system, but compiled into the binary as grayscale bitmaps in Portable Network Graphics (PNG) format. Source: Internet
Glide abstracts out most of the complexity in handling these and other tasks related to working with bitmaps and other images on Android. Source: Internet
Block allocation is tracked by free space bitmaps in fixed locations. Source: Internet
Jaggies in bitmaps, such as sprites and surface materials, are most often dealt with by separate texture filtering routines, which are far easier to perform than anti-aliasing filtering. Source: Internet
