AllPages Property

Summary

Gets or sets a value that indicates whether to clone all the pages if the source image is multi-page.

Syntax

Java

Objective-C

WinRT C#

C++

public bool AllPages { get; set; }

Public Property AllPages As Boolean

public bool AllPages {get; set;}

@property (nonatomic, assign) BOOL allPages

public final boolean getAllPages() 
public final void setAllPages(boolean value)

 <br/>get_AllPages();<br/>set_AllPages(value);<br/>Object.defineProperty('AllPages');

public: 
property bool AllPages { 
   bool get(); 
   void set (    bool ); 
}

Property Value

true to clone all the pages if the source image is multi-page; false, otherwise.

Remarks

If the source image (the image passed to the RasterCommand.Run method) contains multiple pages, then you can use the AllPages property to control whether the CloneCommand will create a copy of the current active page or all the pages in the image.

Note that when the source image has multiple pages and the value of AllPages was set to true, then the RasterCommand.Progress event will fire from 0 to 100 for each page processed. If an overall progress percentage is desired, then you can inspect the RasterImage.Page and RasterImage.PageCount properties of the SourceImage property to calculate this value as shown in the example below.

The default value of this property is false to clone only the current page.

Example

This example will clone a multi-page image and shows the over-all progress value.
