DrawTextWebLink is broken in latest release

[rutzelt]

When using the latest hotfix for Spire.Pdf (commercial version), the insert hyperlink functionality is broken. The text for the hyperlink is viewable on the page but there will be no hyperlink associated with it. Therefore, the link will appear on a page but it will not be clickable. It worked in prior versions.

Bug introduced in version:
Spire.Pdf 3.6.321.4040

Last worked in version:
Spire.Pdf 3.6.131.4040

Sample code:
PdfDocument doc = new PdfDocument();
doc.LoadFromFile(@"files\Upgrade.pdf");

string hyperlinkText = "HLText";
string hyperlinkURL = "www.microsoft.com";
string hyperlinkFont = "Veranda";
float hyperlinkFontSize = 12f;
float x = 100;
float y = 100;

// Draw the image...
PdfPageBase page = doc.Pages[0];
PdfBrush brush = PdfBrushes.DarkBlue;
PdfTrueTypeFont font = new PdfTrueTypeFont(new Font(hyperlinkFont, hyperlinkFontSize, System.Drawing.FontStyle.Underline));

PdfTextWebLink link = new PdfTextWebLink();
link.Text = hyperlinkText;
link.Url = hyperlinkURL;
link.Font = font;
link.Brush = brush;
link.DrawTextWebLink(page.Canvas, new PointF(x, y));

// Use Spire.Pdf to do the conversion...
doc.SaveToFile("broken_hyperlink_test.pdf");

Hi Amy. We are using Spire.Office. The latest hotfix for Spire.Office (which contains Spire.Pdf) is version 3.7.86.4040. That version still has the problem.

Please let us know when you release a hotfix for Spire.Office which contains this correction.

Thank you,
Tom

Dear Tom,

Thanks for your reply.
I tested your code with Spire.Office 2.14.1 (which contains Spire.Pdf version 3.7.86.4040), and hyperlink functionality in the output pdf file is fine. Attached is output pdf file.
Here is my testing code.

Code: Select all

static void Test_7893()
        {
            PdfDocument doc = new PdfDocument();
           
            string hyperlinkText = "HLText";
            string hyperlinkURL = "www.microsoft.com";
            string hyperlinkFont = "Veranda";
            float hyperlinkFontSize = 12f;
            float x = 100;
            float y = 100;

            PdfPageBase page = doc.Pages.Add();
            PdfBrush brush = PdfBrushes.DarkBlue;
            PdfTrueTypeFont font = new PdfTrueTypeFont(new Font(hyperlinkFont, hyperlinkFontSize,   System.Drawing.FontStyle.Underline));

            PdfTextWebLink link = new PdfTextWebLink();
            link.Text = hyperlinkText;
            link.Url = hyperlinkURL;
            link.Font = font;
            link.Brush = brush;
            link.DrawTextWebLink(page.Canvas, new PointF(x, y));

            string output = "broken_hyperlink_test.pdf";
            doc.SaveToFile(output);
            System.Diagnostics.Process.Start(output);
        }

Hi Amy. For your test case, you added a new page and then added the hyperlink. For my test case, it requires that I add the hyperlink to an existing page. This functionality worked in the past but is broken now.

Please make the following change to your test case and you will see the problem:

Change:
PdfPageBase page = doc.Pages.Add();

To:
PdfPageBase page = doc.Pages[0];

The resulting hyperlink will not be clickable.

Thanks,
Tom
