: Can you explain the meaning of "bittbliting" in easy..?
Blit stands for block transfer and is a primary function
in today's graphics systems. Basically, a blit is a
memory copy operation that moves a rectangle
of pixels from one location to another. Both the
source and destination rectangles are the same size,
but in different locations. Sometimes they are both
visible, which is then called on-screen blit. When the
source or destination is from off-screen memory, then
it's called an offscreen blit, which is used in double-buffering
solutions to reduce multiple-write flickering.
