I have a deceitfully difficult problem which I had thought it was easy one at the beginning and yet I have spent more than 3 days on and off in total.
what I simply need to do is to save the print preview of the page to PDF file on server side from code behind initiating by a button click.
I was expecting using an open source and then I thought there would be a code like xyzopencode.savepasgeaspdf(path) but I could not find it. I got really close to solution by saving the PDF but then I realized it did not save the picture it only saved the strings.
I tried the pdfsharp but as long as I see it draws the whole thing from scratch and I am nor sure if I can do it.
The reason I need picture compatible one is I have 3rd party signature controller on my page and my couple of attempts worked without them or any picture but when I added pictures they failed to show to picture or did not create the PDF at all. The perfect solution would be just saving what ever shows up in the print preview as PDF, just like the built in feature of Google chrome (but on server side).

I am facing issues while using ngx-extended-pdf-viewer.I am displaying a pdf using this component.
And at the same time I want to display another pdf in a pop using ngx-extended-pdf-viewer.
The first pdf shows up fine but when I want to view another pdf in a pop up ,the pop up shows a blank screen and the pdf is viewed in the background that is it replaces the first pdf.
I want to view the two pdf's at the same time and the second pdf should view in the pop up.
How can I resolve this?
Short answer: that's not possible. The base library, pdf.js, pollutes the global name space, so there's only one instance of the PDF viewer at max.
But: I believe you can wrap ngx-extended-pdf-viewer in a web component. I haven't found the time to test this, but that should solve the problem.
I Have a classic asp site i am working on. The page has two frames one directly below the other. A Customer has to be able to view a pdf to continue onto the next page. To get to the next page they have to click on a hyper link inside of the pdf that is being viewed. If they cannot see the pdf then they have to download adobe reader which i have included a link to in the top frame.(The top frame has some text and the link) now the bottom frame(contains the pdf) this works fine except when i click the link that is in the pdf the page then opens in that same bottom frame that contained the pdf. It needs to be target _blank. Or whatever you would call it to basically either over ride the two frames and just open in the browser or open in a new tab or window which i cant get either to do. This problem is in IE and Firefox but in chrome it over rides the two frames and opens correctly. Is there any way to get this to occur in IE and Firefox?
I've found this resource about your issue:
http://forums.adobe.com/thread/853394
They say there's no target attribute to set. But they think (and i also think) that if you place a :
javascript:window.open('http://yoururl.com');
it should work, always if you can accept the security alert message (Abobe PDF is trying to execute a script... blah blah)
If your continue reading carefully it seems they solved the problem using Adobe scripting inside inDesign
Hope this helps...
I am creating a Mac App, using NSDocument, that stores a custom class of documents to iCloud.
I was able to get the program to store documents to iCloud quite easily by just Code Signing it, Sandboxing it, and adding iCloud entitlements; however, I'm still encountering a problem where when I trigger an iCloud conflict and the program drops down the sheet allowing the user to resolve the conflict the rows in the sheet do not show the small image of the document (like Preview and TextEdit do).
Additionally, when I click on the area where the image should be (it's blank) it opens up a Quick Look window that just displays an image of the Document Icon together with some other information as opposed to a snap shot of the actual file like Preview and TextEdit do.
I have not found any information in Apple's documentation that explains what I need to do to implement the same behaviour as Preview and TextEdit.
So far I've been surprised by how easily I've been able to get all of the functionability of not only the Auto Saves and the Versions browser, but also saving to the Cloud. NSDocument seems to do all of this for the developer (resolving iCloud Conflicts, etc.), as Apple's documents says it does, but again I'm not getting this other behaviour and I don't want to reinvent the wheel by writing code that is not needed.
I'm thinking that the answer might lie somewhere with implementing a Quick Look thumbnail (for the small image in the table in the sheet) and a Quick Look preview for the larger preview of the document when that in the sheet is clicked on, but this seems like a lot of work and I'm afraid of losing some of the other build-in functions of NSDocument if I start "trapping" NSDocument routines up the food chain so to speak.
Has anyone else encountered this problem and found the easiest solution?
Update: Dec. 25/12
I've finally figured out that the problem is I need a QuickLook generator to display both a QL Thumbnail (which shows up in the table in the conflicts sheet) and a QL Preview (which is displayed when a user clicks on the Thumbnail)
I ended up creating the QL generator project, and afterwards creating a workspace which I added my main project and the QL generator project to. After that I added a Copy Files Build Phase to the main project to copy the QL generator into the main Application bundle.
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.
Situation:
(Large) PDFs are stored on an iOS device
The PDFs are encrypted using a Rijndahl algorithm
When tapping one of the PDFs, it gets decrypted and afterwards viewed using a PDF viewer I implemented. The viewer is using the Core Graphics functionality to render the document page by page.
Issue:
With the documents being large enough, encrytion will take a while.
Viewing can only be started after the whole document has been decrypted into a temp file.
I'm wondering, if there is a way to...
Pass some kind of stream to CGPDFDocument instead of a file URL
Or any other alternative to be able to view as many pages as possible whil decrpytion is continued in the background?
If you cannot split your original PDF files down to single pages (as I suspect), then the following approach should work:
A: When still decrypting:
try to open the PDF document as you already do;
try accessing the document page you are interested in;
if it does not fail, render the page;
if it fails, then you know that page is not available yet (while decrypting);
while decrypting, release the pdf document each time you try to get a new page.
B: when decryption is done: do as you are already doing.
Please note that this is just a suggestion, I have not tried this while decrypting a document, but if point 1. does not fail, then this should work.
