Detailed Description

Implements progress tracking for a filter.

This is a utility class for use by filter implementations in GenerateData() and ThreadedGenerateData().

The class constructor sets the progress to 0, and the destructor sets it to 1. In between, there should be one call to CompletedPixel() per pixel. The reporter will automatically update the filter's progress at an interval resulting in the specified number of updates. The default number of updates is 100.

Example usage:

   ProgressReporter progress(this, threadId,
                             threadRegion.GetNumberOfPixels(), 100);
   for( each pixel )
     {
     ...
     progress.CompletedPixel();
     }

When used in a non-threaded filter, the threadId argument should be 0.

This class is a tool for filter implementers to equip a filter to report on its progress. For information on how to acquire this progress information, see:
