In your example How to remove text from a PDF you show how to remove text in a specific area of a PDF document by passing a pre-defined rectangle to PdfCleanUpLocation, but... where do the rectangle coordinates come from?
I have an existing PDF file on my web server that I need to interact with in a web browser. How can I determine the coordinates of a specific area of the document?
Thanks.

I have added image in existing PDF. Now i want them clickable which will redirect me to Browser using Java itext. Can anyone tell me how to do that?
I developed a Java PDF viewer using Apache PDFBox. The problem is, when rendering a page of a PDF, if the page has file attachments, there is no icon shown in PDFBox rendering, like there is a paper clip icon, when such a file is opened in Adobe PDF reader.
Is it possible to automatically have such icons in the rendering using PDFBox? I think I saw such a code some time ago, like a single line that switches this behavior on and off but I can't find it. Thanks.
This was fixed in PDFBOX-5394 and will be in the version 2.0.26. However only one single symbol will be shown at this time: a paperclip in fixed size.
My requirement is that i have to display list of PDF documents on browser as rectangular boxes. In the rectangular box i need to show PDF document cover page as thumbnail. When user clicks on any rectangular box, calls goes to server side and document will download on client.
We have couple of JQuery plugins that works as PDF viewer but what i need is PDF first page as thumbnail.
My questions is can we achieve this on client side?
If not then i will have to possibly work this out on server side by converting PDF page to image using JPedal/Ghost4J tools and then sending images to client side.
Currently I'm developing an application that allows users to create a template and generate it into a DOCX file. The application needs to be able to display to users the changes in the template as the user is creating it.
The approach I tried was using DOCX4J library (allows manipulation of DOCX file) and ICEPDF which is primarily used to display the DOCX into the swing component by converting it first into a PDF file. Now the problem in this approach is that it loads pretty slow and some of the changes that occurs in the DOCX file does not reflect on the PDF conversion (example: dashed underline, font changes). When I tried to open the DOCX file ouput in MS WORD, the file is viewed correctly so I know changes do occur, but it seems that ICEPDF just can't show it properly.
So I was wondering if anyone knows a java library that allows DOCX files to be viewed directly from a Swing Component instead of converting it first into a PDF file.
You can try docx4all or DocxEditorKit. Both of these are built around docx4j.
Looking for a Java based PDF creation library. We're currently using Apache Velocity with HTML to render PDFs on the fly.
We'd like to be able to find a way to render large images (sometimes as big as 3000 x 1700) in a creative manner within the PDF container. For instance, a scrollable image pane within a PDF. This might not be possible within a PDF, I might be wrong.
Open source would ideal.
For a good PDF library you should take a look at iText: http://itextpdf.com/
I have used images of around 5000x4000 with iText without any problems.
I don't know if it is possible to create a working scrollpane inside a PDF, unless of course you were doing it through a custom PDF creator/viewer.
iText is open source but make sure to check out the AGPL license before you use it commecrially: http://itextpdf.com/terms-of-use/agpl.php
For just creating PDF files from images iText is a little overdimensioned. Give xsPDF a chance, it has no limits for images sizes and seems to be appropriate for your problem.
Just a FYI for anyone that may run into this in the future:
I used a library called PDFBox (http://pdfbox.apache.org/) to open a pre-existing PDF and modify the PDF with a custom sized PDFRectangle with the dimensions of the image. Then inserted the image and rectangle into that new page and got the desired results.
I didn't realize you could have multiple page sizes in a single PDF.
