I would like to know if it is possible to load a PDF and edit it.
The PDF is a brochure with few pages, i would like to put in few images from my database and save it.
Thank you
You can import pages of an existing PDF document with FPDI. After that you can place the images on top of them with the standard Image() method of FPDF.
Editing a PDF is very difficult programmatically, especially if it wasn't programmatically generated.
A better option would be to make your source file an HTML file, then make your edits to the HTML and convert it to PDF.
If this is a one-time task, it would be easiest to open the document in Acrobat (Pro), and exchange the images using the Edit text and Images tool.
Another way with Acrobat would be creating a Button form field over the image to be replaced (transparent border, transparent background, no action). Then you import the new image as icon, and flatten the page afterwards.

Our software #cloudformatter can prepend or append existing PDFs to a formatted div or set of div's.

It is not possible to directly edit PDF file in your browser. All you can do is just get input from user and generate PDF file based on it using fpdf(better use tfpdf for utf support) on your server.
How about you use a tool like TinyMce to edit your data ,grab the output html and create a PDF out of it using MPDF or html2pdf
I'm wondering is this is possible or not?
Suppose i have div containing 10 Questions,Options and Answers.
Now,if user want to copy content of that div he has to manually select and copy the content using mouse and paste on his editor(Ms Word or some other editors).
But what i want is when user clicks the download button the content gets copied to the pdf(or other file) file and can be downloaded.
You need to use fpdf for that
Here's a nice tutorial of how to create a pdf file using PHP
Reference
FPDF is probably the best library to create PDF's in PHP
Check out fpdf website here :
http://www.fpdf.org/
Best for
Multiple layers of text/images
Watermarks
Barcodes much more
Do check out the Scripts section in the website
Great PDF lib for creating PFDs is mpdf just try example, you would be amazed how easy it is: http://www.mpdf1.com/
i think, you need fpdf lib.
to create txto other similiar file from the content of the page:
open/create file
read_page = read the page content
file_put_content(read_page)
file is ready to download
Normally, pdf files can be edited by applications like Adobe Acrobat Writer. And when we open the pdf files in applications like adobe acrobat reader, we can select the contents. I need the codes that can create the pdf file and make it's content uneditable and users can't select the contents.
Please help me out with this.
You can render text and overlay an image. I am not sure whether this will work - viewer applications may allow the text to be selected.
If you render the text as watermark annotations, then that content will not be selectable.
You could encrypt the document and set an empty string as the user password but a full string as the owner password document. This will allow anyone to open the document without entering a password. To prevent content selection, you need to specify deny "content selection" user permission.
Our company Gnostice has PDF components for Java, .NET, and Delphi/C++Builder platforms. All of them can render text and images, create watermark annotations, encrypt PDF document, and also specify usage permissions.
you can use pdf password secure http://luxsci.com/blog/how-secure-are-password-protected-files.html.
On development enviroment using php, i have no idea how to implement it, but it helps... i guess if you convert all your text to image, they never could copy that.
Use this link to know about creating a PDF file using PHP dynamically. http://www.devarticles.com/c/a/PHP/Use-PHP-to-Create-Dynamic-pdf-Files/ In the properties, you can make it read-only.
Save the PDF file as an image. Then create a PDF of that image. If the PDF is multiple pages, you may want to consider saving it in a multi-page image format such as a tiff. Otherwise you will end up with 1 image per page if using say, the jpeg format and then have to combine them into one PDF Document. I do this with Services Agreements all the time.
I am trying to create an interface to allow easy editing of PDFs like VuePDF in an application I am building. This is not core to the application and will only be used by the admin.
I was wondering if there was a per-built stack for editing PDFs in the browser window?
Basically the admin user needs to black-out private data, like names and addresses.
If there is not currently a solution I was thinking of some like:
Using ImageMagik to create JPEG version of each page
Using the canvas element to add black marks to the image
Recording the location of top-left and bottom right of each black mark
Sending back the coordinates and adding black rectangles to the original PDF
Is that correct?
If you draw over the PDF, the data will still be there in the PDF and easy to extract. I wrote a blog article explaining the issue at http://www.jpedal.org/PDFblog/?p=553
You need to replace the text in the PDF command stream as well.
