Is there any API in js or .net or any other free tool through which page coordinates can be obtained in a pdf? Basically, I have a pdf file which contains images so I have read the coordinates on click inside the pdf document.
*coordinates here refer to .pdf page coordinates and not pixel coordinates, however I used itext library but couldn't figure out the solution.
In order to read the coordinates of an image when it's clicked on in the PDF, you're going to need to use a PDF viewer that is capable of running scripts. Unfortunately, there are only a few of those and they all implement only a portion of the Acrobat JavaScript API but the Acrobat JavaScript API can't tell you anything about images or their location so it's doubtful that any of the others would. However, you could create a plug-in to Reader and/or Acrobat and add that functionality but then all of your users would need to install both Acrobat/Reader and your plug-in.
Assuming I understood the user experience you are looking for, I don't think it's possible without a customized viewer.

Does anyone know if there is a function in PDF's to allow them to auto-adjust the view depending on whether it is on a desktop or mobile? Or even by screen size?
I am looking to prepare PDF material for distribution, however, on the user group includes a mix of desktop and mobile, so instead of creating two PDFs I would like to have a single PDF which adapts to the users screen?
This is not possible with PDF files up to PDF version 1.7, the most commonly used on out there.
PDF 2.0 which was released three years ago has such a feature but it depends on the viewer implementing it and the PDF writer correctly annotating the PDF. I guess there are PDF viewers out there that can already do this but I'm not specifically aware of any.
If I were you, I would write the document in a format like LaTeX that can easily be converted to both kinds of PDFs, one for desktop and one for mobile.
I want to extract the coordinates of a PDF document with the help of a mouse click. I have gone through some posts but since I'm new to this, I'm not being able to understand it properly. Also, can this be done if I render the PDF file in a web page?
You can add javascript to a pdf document. Although you only get access to a limited subset of the language.
If you only need the coordinates once (for instance when doing layout of the document), you can simply open it with adobe and activate the rulers/grid option to see where your mousepointer is currently located.
I need to display a PDF in an ASP.NET web page and specify the Zoom, X/Y coordinates and page to display. Can this be done?
Thank you
It is possible to use Adobe reader and enter parameters when opening the PDF:

You might be able to pull it off with, say, a Flash PDF viewer (for example, see Scribd) for the best cross-platform (Windows, OS X, Linux) solution.
If you just want to embed PDF in a web page, you might have to use an iFrame and use browser capabilities (Adobe Reader plugin, Google Chrome PDF reader) if you want to support all browsers.
We are using Blackberries to display PDF reports. Here are background details on the problem:
The PDF reports are created using JasperReports.
Report format can be changed.
Different report formats are available (as per the feature set of JasperReports).
The PDF reports are on a website, too, so retaining a single source is ideal.
The page setup is in Landscape.
Here are the issues we have encountered:
Users cannot see a full line of text on the Blackberry.
The size of the PDF and UI makes reading difficult, at best.
The menu option to convert the PDF to text loses too much formatting to be useful.
The text is blurry (and too small).
Here are solutions we have thought about:
Create a second report (not ideal) in text or HTML format.
Simplify the original report format (not really an option, given the amount of data).
What other options are there for making a report available on the Blackberry, given the constraints of JaserReports, such that the report:
Is legible?
Is formatted for readability?
Displays quickly?
Essentially, we'd like to make sure there are no simple solutions we have overlooked for displaying legible PDFs on Blackberries.
We convert TIFFs to PDF for one of our applications, and have had mixed results with BlackBerry PDF viewers. These were our results.
Working
The following PDF readers worked for our purposes:
RepliGo Reader v1.1.1.1 - $19.95
Works fine.
DataViz Documents To Go Premium Edition v1.003.001 - $49.99
Works and includes a word wrap option to get the current zoom level to fit the available screen width, by moving text onto subsequent lines. Might fit your needs.
Non-Working
The following PDF readers did not work for our purposes:
BeamReader v1.0.8 - $17.99
BeamSuite v3.0.2 - $49.99
These couldn't open our PDF files ("Unsupported document format"). In addition they did not register as a PDF content handler, required for our application.
MasterDoc - $19.95
eOffice - $29.95
These also did not register as a PDF content handler. We had a range of problems with these, including installation issues, and not being able to open any PDFs at all.

I hear it's the best at reading PDFs for BlackBerry
How about outputting the file to an RTF or an image file (JPG/GIF), and then viewing them in your web browser?
If that doesn't work well on the native browser, I would focus on viewing the file via some other web browser - for example, Opera Mini. I know for images it's easier to navigate "big" images in Opera Mini than the native browser.
If your blackberries are on a BES server, couldn't you display the reports as HTML on your corporate intranet? - Then you could email a link to the blackberry and simply browse the report.
You can convert pdf to image via xpdf and than show image. xpdf is a BEST renderer of pdf.
I've already referred to this SO post. I've been embedding images using an AlternateView for PNG files. Now I'm wondering how to do it with PDFs.
Should it work, for the LinkedResource, to just say:
Dim document As New LinkedResource(pdfFilePath, "image/pdf")
I'm just trying to figure out how to get the PDF to be embedded like I could with an image, or is that not possible and I'll have to do it as an attachment?
You can embed images since they can be rendered in place by an email client. PDFs cannot do that, so I'd recommend either having a thumbnail of the PDF that links to your web site with the actual PDF. Or just attach the PDF to the email message.
There are a few options that I know of.
1) Is the simplest way okay? The easiest by far would be to attach the PDF as a normal attachment. Then render the first page of the pdf as an image, embed it in the email and link it to open the PDF if you can. Entourage kind of does this on the Mac.
Alternatively, what I found was the following:
2) FLASHPAPER embedded in HTML displaying a PDF. Adobe has a technology called Flashpaper. It is a flash based file viewer. You can use flashpaper format documents that go into it, or PDFs as the source.
Check out some examples. That's really flash. http://www.adobe.com/products/flashpaper/examples/
Assuming you send an HTML email that will get through (images aren't turned off, etc), you can can embed the Flashpaper viewer right in your HTML code as a normal Flash object.
Most HTML email clients use Internet Explorer Bits, Webkit bits, or Gecko bits to render the html. Flash player is pretty well installed on everything, so it works well. A good example of this is when we open an email and it has video playing in it. It's almost always Flash.
I have had luck doing it this way -- the only thing you'd have to decide is if most of your clients can see this and how much (if any) today's software might block it.
What I ended up doing was a hybrid. 1) Attach it to the email, 2) Embed the Flashpaper viewer. They get it either way.
Flashpaper is available seperately for $75. It has come in handy where the client was not able to install adobe acrobat on each computer and it had to be 100% web based.
I would imagine you should be able to do the same using any language with a little more effort and using something like Flashpaper.
Hope that helps
This is not possible--at least not in a way that will work with many clients. You'll need to just attach the file.
If you have only one client to worry about, it might be possible--but not likely without manually changing settings on each client.
The MIME type of a PDF is "application/pdf" not "image/pdf"
