How to add floating button in PDF? - pdf

I would like to add a floating button in PDF. However, after doing a lot research on internet, I didn't find any answers.
I would like the button to float/move across the pages with the scroll bar as the document is scrolled. Is there a way to implement it in PDF?
Note: I would prefer to not to use JavaScript to implement it.
Thanks in advance.

As #mkl commented, it is not possible to add a floating button in PDF without using JavaScript.
PDF is meant to be used for fixed layout and not dynamically change as it is being viewed.
The closest I could find to what you are looking to do is this article about creating text that shows/hides depending on where the cursor is. I can't think of a way to leverage this though to change the position of a button as a user scrolls and even then you would most likely run into different PDF viewers handling it differently.

Extract PDF coordinates using mouse click

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.

Possible to control PDF layout with iText?

I'm writing some logic to build a large single PDF file that our users can print at their convenience. I'm using Java's iText library (through Clojure's clj-pdf).
I'm trying to have the PDF show the same exact template form on every single page, however I can't seem to find any documentation or indication that one can have PDF content "fit to a page".
The text in these forms varies a little bit, so there's a chance it might require more of fewer text lines per page. This means that the content has a chance of spilling over to the next page, or being too short, making the next page creep up into the previous one, breaking the requirement of "one form per page" for the rest of the document.
I'm trying to figure out if my option is pretty much only to manually check the length of the text on each page and potentially crop it by hand if I goes over n lines, or if the PDF format somehow supports a smart way of having paragraphs+tables+headings all fit in one page. Some UI systems allow you to control how spill-over is handled, anywhere from cropping to resizing the font, so I'm curious if PDF supports anything of that sort.
Edit: ended up going with pagebreaks for simplicity, wasn't aware of that option when I wrote this question.
If you want to take control over the space taken by text, for instance to fit it on a single page, the way to go would be to create a ColumnText object and to add the content in simulation mode. If the text fits the page, add it for real. If it doesn't, use a smaller font size. This is demonstrated in the MovieAds example where snippets of text are fitted into AcroForm fields.

Edge Animate Automation

Most Adobe products have the ability to be automated using AppleScript or ExtendScript/JavaScript but I don't seem to see the same capabilities in Edge Animate. Maybe I'm just missing something. I'm looking to be able to do things like open the document, add images, save the document, etc. Has anyone been able to find anything like this? I've done a number of different searches to no avail.
I'm not exactly sure what you're asking, but I think you're talking about adding your own javascript, which can be done by clicking the curly brackets located next to any of the elements in the animation, or hittin ctrl+E to see the full code.
Second, in terms of opening the document, you should be able to just double click the an file that it creates, and saving the document is just like in any other program, file>save(as).
Adding images is as simple as file>Import (hotkey = ctrl + I).
not exactly what I was asking for, but I did end up finding a solution. I was looking for a mechanism to be able to control Edge Animate similar to how you can control InDesign, Photoshop, and Flash via VBScript, and JavaScript respectively. This allows you to do things like import images into your document from an external script, save the document, export contents, etc. In the end, I wrote some code that sends key-strokes to the application and that resolved the problem although not ideally, IMHO. Thanks for your responses, though.

Extract screenshot or picture of portion of PDF using VBA or VB and Adobe SDK

I am currently using an excel macro (although I will switch to VB.NET if necessary) to loop through all of the text in a PDF and populate an array with certain portions of the text in the PDF (via the Adobe SDK and getPageNthWord). This part is working just fine, but now what I want goes a step further.
There are certain portions of the PDF where just grabbing the text isn't giving the full picture, and I'd like to see what more I can get. This is exactly the screenshot or snippet I am trying to get:
So, I know that I could use getPageNthWordQuads to find the coordinates for the words "Compliance Warning" and I could figure out a way to find the bottom right of the screen as well, but my problem starts there. After I get those coordinates what would I do with them? Can I zoom in the PDF to only see that portion and then take a screenshot? I already have the code for a screenshot of the activewindow, but I don't know how to scroll or zoom on a PDF.
Any help would be greatly appreciated. A fresh approach would be welcome as well. Thanks!
There are probably a number of approaches that would work - I don't know enough about your environment / constraints to know for sure which would work best. I'm assuming you are talking to Acrobat through OLE here.
1) You can open a window, get its AVPageView and ask it to zoom and move to where you want it to do your thing.
2) You can open a PDF document in one of your own windows using OpenInWindowEx and then grab the contents of that window (the advantage being that this window could be off screen).
3) You can use the DrawEx method (in AcroExch.PDPage) to render a specific portion of a page into your own window and then process that.

iText create pushbutton at relative position

I'd like to create a pushbutton on a pdf using iText. However i cannot create it at any fixed/ position. It needs to be done at a relative position. Like say, 5-6 cm. before end of PDF.
Any idea on how to do it?
Another way might be creating an invisible field in acrobat, getting its field position and then creating the button at that position. However i've been unable to retrieve field positions or even view them. Could someone help me with this?
Regards,
Sameer
you should always know the size of your pages, and if you know that you will be able to put it at a relative 5-6cm of the page. some info that might help you is that all the coor and stuff in itext is done in points and there are 72pts in an inch.
