Declaration ​

pascal
TParallelRegularRasterizer = class(TRasterizer)

Description ​

TParallelRegularRasterizer utilizes Delphi's Parallel Programming Library (PPL) TParallel.For loop to distribute scanlines evenly across the system thread pool.

By utilizing a persistent system thread pool, TParallelRegularRasterizer avoids thread creation overhead on repeated rendering calls.

Note

First invocation may incur a minor performance penalty as the runtime thread pool warms up.
