Bit BLIT (which stands for bit-block alteration but is arresting bit blit) is a computer cartoon operation in which several bitmaps are accumulated into one application a raster operator.
The operation involves at atomic two bitmaps, a antecedent and destination, possibly a third that is generally alleged the "mask" and sometimes a fourth acclimated to actualize a stencil. The pixels of anniversary are accumulated bitwise according to the defined raster operation (ROP) and the aftereffect is again accounting to the destination. The RasterOp is about a boolean formula. The a lot of accessible ROP overwrites the destination with the source. Other ROPs may absorb AND, OR, XOR, and NOT operations. The Commodore Amiga's cartoon chipset, for example, could amalgamate three antecedent bitmaps according to any of 256 argumentation functions of three variables.
Modern cartoon software has about absolutely replaced bitwise operations with added accepted algebraic operations acclimated for furnishings such as alpha compositing. This is because bitwise operations on blush displays do not usually aftermath after-effects that resemble the concrete aggregate of lights or inks. Some software still uses XOR to draw alternate highlight rectangles; if this is done to blush images the abnormal consistent colors are calmly seen.
