CreateLocalLink changing the zoom

Aspose.PDF Product Family
1

I am taking an existing PDF file and adding some local links using the CreateLocalLink() method. It all works fine except that when I click on the link it changes the current zoom value to “Fit One Full Page to Window.” For example, if I set the zoom to 100% and then click on a link, the zoom changes to “Fit One Full Page to Window.” I don’t want it to change to this new zoom value. When I click on the link I want it to stay at the 100% (or whatever the current zoom is) that I had it set to.


Is there a way to maintain the current zoom?

Here is the code:

string outputFile = tbPDFFile5.Text;
Document finalDoc = new Document(outputFile);

var contentEditor = new PdfContentEditor();
contentEditor.BindPdf(finalDoc);

System.Drawing.Rectangle gobackTextRc1 = new System.Drawing.Rectangle(50, 725, 105, 16);
contentEditor.CreateFreeText(gobackTextRc1, “Go Back to Page 1”, 2);

System.Drawing.Rectangle gobackRect1 = new System.Drawing.Rectangle(50, 725, 105, 16);
contentEditor.CreateLocalLink(gobackRect1, 1, 2, System.Drawing.Color.Red);


System.Drawing.Rectangle gobackTextRc2 = new System.Drawing.Rectangle(50, 725, 105, 16);

contentEditor.CreateFreeText(gobackTextRc2, “Go Back to Page 2”, 3);

System.Drawing.Rectangle gobackRect2 = new System.Drawing.Rectangle(50, 725, 105, 16);

contentEditor.CreateLocalLink(gobackRect2, 2, 3, System.Drawing.Color.Red);

outputFile = outputFile.Insert(outputFile.Length - 4, “_2”);
finalDoc.Save(outputFile);

I have attached a sample PDF file showing my dilemma.

The described behavior is not a bug. The CreateLocalLink method creates a link that changes the page’s zoom to fit the entire page within the window.

To create a link without changing the zoom, you can use the following code snippet:

static void Main(string[] args)
{
    var input = "input.pdf;
    var output = "output.pdf;

    Document document = new Document(input);
    var contentEditor = new PdfContentEditor();
    contentEditor.BindPdf(document);

    System.Drawing.Rectangle gobackTextRc1 = new System.Drawing.Rectangle(50, 725, 105, 16);
    contentEditor.CreateFreeText(gobackTextRc1, "Go Back to Page 1", 2);
    System.Drawing.Rectangle gobackRect1 = new System.Drawing.Rectangle(50, 725, 105, 16);
    CreateXYZLocalLink(document, gobackRect1, 1, 2, System.Drawing.Color.Red);

    System.Drawing.Rectangle gobackTextRc2 = new System.Drawing.Rectangle(50, 725, 105, 16);
    contentEditor.CreateFreeText(gobackTextRc2, "Go Back to Page 2", 3);
    System.Drawing.Rectangle gobackRect2 = new System.Drawing.Rectangle(50, 725, 105, 16);
    CreateXYZLocalLink(document, gobackRect2, 2, 3, System.Drawing.Color.Red);
    document.Save(output);
}

private static void CreateXYZLocalLink(Document document, System.Drawing.Rectangle rectangle,
    int destinationPage, int originalPage, System.Drawing.Color color)
{
    var link = new LinkAnnotation(document.Pages[originalPage], Aspose.Pdf.Rectangle.FromRect(rectangle));
    link.Color = Aspose.Pdf.Color.FromRgb(System.Drawing.Color.Red);
    link.Destination = XYZExplicitDestination.CreateDestinationToUpperLeftCorner(document.Pages[destinationPage]);
    document.Pages[originalPage].Annotations.Add(link);
}
