TotalPercent Property

Summary

Gets the overall completion percentage for the save operation.

Syntax

Objective-C

C++/CLI

Java

Python

public int TotalPercent { get; }

@property (nonatomic, assign, readonly) NSInteger totalPercent;

public int getTotalPercent()

public: 
property int TotalPercent { 
   int get(); 
}

TotalPercent # get  (CodecsSaveImageEventArgs)

Property Value

A number between 0 and 100 that indicates the overall completion percentage of the save operation. The default value is 0.

Remarks

Using the PagePercent and TotalPercent properties, you can use the CodecsSaveImageEventArgs to show a progress bar of the current save operation.

When saving a multipage file, PagePercent will go from 0 to 100 for each page saved while TotalPercent will go from 0 to 100 only once during the whole page operation. Usually, you will use TotalPercent to show an overall save progress if the multipage image is considered to be one document. If however, individual progress is required for each page, then you can track the PagePercent property as well.

When saving a single page file or one page to a multipage file, both PagePercent and TotalPercent will go from 0 to 100 simultaneously.

      // Remember, this is 24-bits/pixel 
      for (int x = 0; x < scanlineLength; x++) 
      { 
         scanline[x] *= 2; 
      } 
 
      // Copy it back to the event buffer 
      e.Buffer.SetData(y * scanlineLength, scanline, 0, scanlineLength);
