Hi,

I am trying to display a pdf document using weblink, on an iframe but it doesn't display it correctly. If document is an image file, it shows it correctly but in case of a pdf document webaccess downloads it immediately whereas weblink displays only text portion of it.

Any help would be greatly appreciated.

Thanks

It is not possible to convert electronic document to pages from workflow as workflow cannot communicate with LF Client.

Hi Junaid,

To verify, you are displaying a PDF from Weblink into an iFrame and it's giving you the File Download message instead of just displaying it?

This is possible and I confirmed it with the following HTML:

<html>
<head>
<title> Test </title>
</head>

<body>
<div>
<iframe id="fred" style="border:1px solid #666CCC" title="PDF in an i-Frame" src="https://lf.rochestermn.gov/Documents/0/doc/3420/Electronic.aspx" 

frameborder="1" scrolling="auto" height="1100" width="850" ></iframe>
</div>
</body>
</html>

Be sure to verify the mime-type of the document. If it is "application/octet" it will not be executable from the web browser due to enhancements in security in WebLink 9.

If it is "application/pdf" then it will tell the browser it's a pdf and the browser will check the local settings to determine if it should be downloaded or opened. Firefox and IE have different settings for this so be sure to verify each browser and the following instructions. https://helpx.adobe.com/acrobat/using/display-pdf-in-browser.html

The last spot to check would be any cross-site scripting (XSS) issues.

Regards,

Carl

Have you tried using the link going direct to the electronic file?

The DocView url you're using above will take you to the generated images or pages of a Laserfiche entry. Not the actual pdf.

Thanks. This is exactly what i was looking for. One thing i would like to mention here is that links structure mentioned above didn't work for me.

http://servername/laserfiche/ElectronicFile.aspx?db=repositoryname&id=id

Instead i had to use something like this

http://servername/laserfiche/edoc/repositoryname/id/name.pdf

Also, if you send above mentioned url from workflow it doesnt work as /%(id) in workflow token are considered part of url, hence you have to use //%(id) to make it work.

Hi Junaid,

We're working on being able to natively display PDFs directly in the Web Access document viewer and plan to include it in the upcoming Laserfiche 10 service pack 1 release, currently targeted for March. I'm showing it in the Coming Attractions course at Empower 2016 if you're attending.

Super helpful thanks! The generated URL pattern was not displaying PDF files in the browser. Seems all the support articles on Weblink URLs point to using the generation activity in workflow now. It seems like years ago there was a more detailed description of how to construct these URLs

Justin,

Is this now built into Weblink?

Does the PDF have any pages associated with it? I found that in order to correctly display PDFs in WebLink I had to "generate pages" for each PDF in client before they would display in WebLink.

Is there a way to generate pages for specific electronic document from workflow. I am looking into sdk and i have found something but not sure it will work.

sdk generate pages.png (72.6 KB)

I have not found a way in workflow but have been able to do it in quick fields. I am guessing that you are talking about a number of documents and it would not be timely to do it manually in client?

Yes. Converting electronic document Manually to pages is not an option since files are created dynamically and could be in large numbers.
