ParallelImage Class Reference

#include <parallelimage.h>

Detailed Description

This is a utility class for parallel processing of 2d data - usually images. The per pixel computations are distributed to several threads. This is intended for time consuming computations, it makes no sense to call this to clear all pixels of an image.

Process()

static void Process ( Int  width, Int  height, Int  tileSize, const WORKER &  worker  )

static

Invokes the worker method for all pixels of the image (uses dynamic distribution).

Parameters

[in]	width	Image width in pixels.
[in]	height	Image height in pixels.
[in]	tileSize	Initial tile size to be used (a tile will be tileSize pixels wide and tileSize pixels high)
[in]	worker	Lambda or object with operator (), will be called for every pixel (concurrently from different threads)

Template Parameters

WORKER

A class containing an operator ()(Int x, Int y) used for the loop.
