Member Function Documentation

bool ImageResizer::doFinish ( bool  success )

protectedvirtual

Called after all doWork have finished.

Parameters

success

indicates whether all doWork returned true.

Reimplemented from ParallelTask.

bool ImageResizer::doPrepare ( int  nrthreads )

protectedvirtual

Called once, before any doWork is called.

Reimplemented from ParallelTask.

bool ImageResizer::doWork ( od_int64  , od_int64  , int    )

protected

od_int64 ImageResizer::nrIterations ( ) const

protectedvirtual

Returns

the number of times the process should be run.

Implements ParallelTask.
