Hi,

I just found out about Quick PDF library today and I have downloaded a trial version. So far, I am loving it, given that version 17 has Qt support as well.

My request is pretty straightforward:

1. I have a main PDF file which is a transcript.

2. Each transcript file has 1 or more exhibits.

3. These exhibits need to be attached to the transcript PDF.

4. Certain keywords in the transcript PDF need to be hyperlinked to open the associated attached (embedded) PDF exhibit file.

So far, using

AddEmbeddedFile

AddFileAttachment

I am able to attach the exhibit files and the attached files appear as thumbtacks/pins.

Now, I would like to take care of Requirement 4 in my list above. I am not sure if it is possible with Quick PDF library but would appreciate any advice.

Thank you,

Ashish

Hi Ashish,

you can add links and you can visualize them with text but not the other way round.

Here's a sample:

https://www.debenu.com/kb/add-links-pdf-programmatically/

There's no comfortable way adding links to existing textcontent.

It's possible to extract all text - word by word with position data - and then you can create a new pdf with all the links repositioning the text.

I fear this won't look very nice ;-)

Cheers and welcome here,

Ingo

Thanks Ingo. I will take your sample code and see how it turns out. I will post my results here as well.

Thanks again for the quick response.

Hi Ingo,

Thanks for the link and I tried it. It does pose some challenges but I am willing to give it a shot by extracting all of the text and the box coordinates using Quick PDF.

Here is my sample code based on the example you provided a link to:

	int nEmbeddedFileId = dqpdf.AddEmbeddedFile("exhibit1.pdf","application/pdf");

        nRet = dqpdf.AddFileAttachment("Exhibit 1",nEmbeddedFileId);

        nRet = dqpdf.SetOrigin(1);

        nRet = dqpdf.AddLinkToEmbeddedFile(200, 100, 60, 20,nEmbeddedFileId,"Exhibit 1","Exhibit 1",6,50);

	    nRet = dqpdf.SetTextColor(0,0,1);

        nRet = dqpdf.SetTextUnderline(1);

        nRet = dqpdf.DrawTextW(205, 114, "Click me!");

        nRet = dqpdf.SaveToFile("dqpdf.pdf");

I can see that the file does get a Click me! text in blue color with an underline so it can look more like a link, but I have to double click it to open. Is there any way to just click once and get it to open?

Please keep in mind that the embed-functionalities are only supported by the adobe products.

Single click actions aren't supported.

I think this would collide with functions like mark and copy?

What you can do is embed some javascript action to get the described behavior.

Thanks for the clarification.

When you say javascript action, can you give an example?

Thanks

With QuickPDF you can embed Javascript-code into your pdf and you can assign an action to it.
In the online reference and the developer guide you'll find the functionalities and samples.

The JavaScript-functionalities:
https://www.debenu.com/docs/pdf_library_reference/JavaScript.php
The types you can use:

Open the developer guide and search with javascript:
