PDFsharp & MigraDoc Foundation

I am having some trouble adding a clickable text that would open a browser to a certain page. For example, if I do this:

gfx.DrawString("http://www.yahoo.com/", font, XBrushes.Red, new System.Drawing.PointF(15, 62));

It works, but what I want is to have a text that reads "Click Here" or an image that when clicked in the PDF would take the user to the web browser.

I tried this:

XFont font = new XFont("Verdana", 20, XFontStyle.Bold);
XSize size = gfx.MeasureString("Click Here", font);
XRect rect = new XRect(new XPoint(15, 10), size);
gfx.DrawString("Click Here", font, XBrushes.Black, new System.Drawing.PointF(15, 30));
PdfSharp.Pdf.Annotations.PdfLinkAnnotation pla = doc.Pages[0].AddWebLink(new PdfRectangle(rect), "http://www.yahoo.com");

I verified that the rect is in fact over the text (I made a box to make sure). But when I open the PDF in a viewer the link doesn't exist.

I also tried this:

paragraph.AddHyperlink("Click here", MigraDoc.DocumentObjectModel.HyperlinkType.Url);

But I don't know how to add the URL and also, the text doesn't even get rendered on the page...

Any ideas as to how I can add a hyperlink without actually displaying the entire link?

Thank you,

Iulian

The AddXxx functions in MigraDoc always return the newly created objects for further modification.



Your "Click here" would be given with AddFormattedText.

Thank you! It works!

But I have one more question: I add the proper URL (I verify in the debugger that the Name property of the link is indeed the URL that I need); but when the PDF gets generated the URL pointed is some kind of giberish. Here is an example:

The url I set:
http://www.mysite.com/vacation-rentals/ ... index.aspx

And this is the url pointed by the PDF:
http://localhost:8080/qìC\Sbzyü—ÍŒ¬V¤7ô큟dîhÀÝîžW2pl

(localhost:8080 is the server where I am testing the application). Do I have to do something else to pass the proper link address?

Thank you,

Do you create password-protected PDF files?
The code works - but we only use unprotected PDF files. Maybe there's a bug with the security settings.

Does the URL contain characters that need escaping?

Thomas, you were correct: the securitySettings.OwnerPassword was the culprit. Once I removed the password the Urls are no longer garbled. This means that there is a bug somewhere that encrypts the Name value of the hyperlink as well and that's why it wasn't working...

Thank you!

It seems the bug already exists in 1.32.
Is there a workaround for using links in encrypted PDF?
Or can you tell me where i can fix that bug?

I am running into this as well - encrypting a PDF messes up any hyperlinks on it.
Other than leaving the doc unprotected, is there any way to remedy this... is there a bug fix in the works?

I have run into the same problem, and a few more regarding the password protection.
Here is the "workaround" I determined.
1. Save the file without setting any passwords or setting any other security items (e.g. noprint)
2. Reprocess the file changing only the security settings.
3. links are retained and not messed up. Passwords are intact.

BEWARE: the other bug I found was setting only a owner password. No good. You can set only a user password. You can set a owner and a user password. But not just a owner password. Here is the "workaround" I determined.
If there is only a owner password, set both the owner and user password to same value.
