Page Property

Summary

Image page number to display.

Syntax

C++/CLI

C++

public int Page { get; set; }

public: 
property int Page { 
   int get(); 
   void set (    int ); 
}

public:  
   property Int32 Page 
   { 
      Int32 get() 
      void set(Int32 value) 
   }

Property Value

The 1-based page number index in Image to display. The default value is 1.

Remarks

Set up the RasterImageList control to an individual page of a multipage file in each item. To do that, simply set the Image property of each item into the multipage image, then set the Page property to the desired page.

The value of RasterImage.Page is not used to control the page number of the item to be viewed in this item. Instead, use the Page property. This allows the same Leadtools.RasterImage object to be used multiple items while setting the Page property to different values.

Example

This example will create and populate a RasterImageList control with thumbnail of the pages in a multipage image file.

using Leadtools.WinForms; 
using Leadtools; 
using Leadtools.Codecs; 
 
public void RasterImageListItem_Page(RasterImageList imageList) 
{ 
   // Initialize the RasterCodecs class 
   RasterCodecs codecs = new RasterCodecs(); 
 
   // Clear existing items 
   imageList.Items.Clear(); 
 
   // Load a multi-page file 
   string fileName = Path.Combine(LEAD_VARS.ImagesDir, "eye.gif"); 
   RasterImage image = codecs.Load(fileName); 
 
   // Create the items (1 for each page) 
   for (int page = 1; page <= image.PageCount; page++) 
   { 
      RasterImageListItem item = new RasterImageListItem(); 
 
      item.Image = image;  // Use the same image for all items 
      item.Page = page;  // But with a different page number 
      item.Text = "Page " + page.ToString(); 
 
      // Add the item to the image list 
      imageList.Items.Add(item); 
   } 
 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images"; 
}
