Develop a reader plugin

Hi I am a dev (not a co.) & want to develop plugin for Adobe Reader, I'd like to know licencing policy for developng a plugin for reader. Would request your replies/suggestion at the earliest ?

But note that if as an invidual you want to develop to save yourself from buying Acrobat, that will not work as you will need Acrobat to develop the plug-in.

Adobe Reader plugins development

shoIs it possible to develop and use plugin for Adobe Reader XI without any registration (RIKLA)?
I have tried to build and test BasicPlugin from SDK samples. It works but shows message "invalid plugin detected. Adobe Reader will quit" after 3-4 second.
From documentation:
There are three types of plug-ins:
1.Regular plug-ins. The samples in the SDK are of this type.
2.Reader-enabled plug-ins. These are plug-ins that are developed with permission from Adobe and that require special processing to load under Adobe Reader.
3.Certified plug-ins. See “Certified Plug-ins”
So I thought that I can create and use Regular plug-ins for Adobe Reader.
Also option "Use only certified plug-ins" is not set.

"Regular" means for Acrobat. You have to get a special license (or permission) from Adobe to develop Reader plugins.

My Adobe Reader Plugin does not Load in Some Machines

Hi ,
I have created a Plugin for Adobe Reader 9 and Adobe Reader X.
As per the licence it has to work with both the version.
My plugin gets loaded in Adobe Reader 9 and Adobe Reader X versions only in development machines and few of the testing machines and My plugin works fine in these machine as per the task it has to do.
I tried to test My plugin in some machines which has same configuration as that of the machines where My plugin was able to load, but i could see My plugin loaded only in some machines and all other machine its not getting loaded.
Please some one let me know why is this happening and how to overcome this. I think i am missing something to load My Plugin but in some machines i was able to load My plugin without doing any settings other than copying My plugin's .api file to Reader Plugin's folder.
Thanks in advance. Please some one help me out.

Hi Irosenth ,
I was getting the below error when i saw the EventViewer.
Error : Activation context generation failed for "C:\Program Files\Adobe\Reader 9.0\Reader\plug_ins\MyPlugin.api". Dependent Assembly Microsoft.VC90.DebugCRT,processorArchitecture="x86",publicKeyToken="1fc8b3b9a1e18e3b",typ e="win32",version="9.0.21022.8" could not be found. Please use sxstrace.exe for detailed diagnosis.
Now i added the required Redistributables while packing all the files and tested it in target machine..
All is Well Now..., Thanks you Very Much. ...
Thanks and Regards,

Internet Explorer ONLY passes parameters to Adobe Reader plugin for hosted files, not local

WORKS:
<embed src="http://host.com/test.pdf#page=5"/>
FAILS:
<embed src="test.pdf#page=5"/>
Both code snippets above work when the HTML file is hosted (IIS / Apache). My web-app needs to be able to run from a USB memory stick and work with IE9. The #page param is required for a core feature of the app.
Parameters after the # are passed correctly to the Adobe Reader plugin in Firefox for offline files, eg: file:///C:/test.htm. The documentation only describes hosted examples: http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/pdf_open_parameters.pdf
I have tried the <object> route as well with similar results, eg: http://pdfobject.com/
I have burned over 8 hours looking for a solution. I have tried any logical settings in Adobe Reader X, and with the security zones in IE. I am not very familiar with IE security zones, but I suspect it could be related to my issue. I can specify the end-user change any browser or plugin settings as an acceptable solution.

I am developing a hybrid web-application that needs to work both offline (entire website) and in a hosted environment. A key part of the product is displaying PDF's with a dynamic index outside of the PDF. This allows us to use PDF's collected from hundreds of contractors, clients and manufacturers and combine them into one searchable product with a consistent interface. I can specify product requirements including IE browser settings, installed plug-ins etc. I am not trying to cater to a wide audience such as everyone online, but a specific one that is spending $5k-30k for a custom resource.
I expect the limiation is due to a wide cast net regarding security. I tried every setting in IE and essentially fully disabling all security options did not resolve it.
I found a solution, by accessing the ActiveX object directly you can use the exposed classes described here: http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/wwhelp/wwhimpl/common/html/w whelp.htm?context=Acrobat9_HTMLHelp&file=IAC_API_OLE_Objects.103.167.html
Javascript:
var pdfO = document.getElementById('pdfObj');
pdfO.setCurrentPage(pageNumber);
HTML:
<OBJECT id ="pdfObj" data="test.pdf" TYPE="application/pdf">
<a href="test.pdf">Fall-back code</a>
</OBJECT>
This actually works much faster as well, since the plugin doesn't need to be re-drawn in the DOM

How to automate the Acrobat Reader plugin in Internet Explorer

Hi,
I have been trying to figure out how to automate the Acrobat Reader plugin in Internet Explorer. My goal is to find a way to allow users of our web application to print PDFs to the default printer without having to go through the plugin's GUI. Our application includes a browser helper component, and I had hoped it would be possible to use the IWebBrowser2 interface's get_Document() method to get at some sort of interface to the plugin (as is possible for, say, a Word document hosted in Internet Explorer) and then use this to print the document. However, this does not work: get_Document(), when called on an IWebBrowser2 instance with a PDF loaded, returns E_NOINTERFACE. I also tried calling the IWebBrowser2 interface's ExecWB() method with OLECMDID_PRINT, OLECMDEXECOPT_DONTPROMPTUSER, and PRINT_DONTBOTHERUSER, and printed a blank page rather than the PDF.
Is it possible to do what I am attempting? Like I said, my core goal is to print a PDF from within Internet Explorer without requiring user interaction. I'd appreciate any suggestions as to how I might accomplish this -- it doesn't _have_ to be by automating the plugin (maybe that is a the wrong approach... though it sure would be nice if the plugin provided access to its object model via IWebBrowser2->get_Document()).
Thanks in Advance,

IF that were entirely true, then the whole purpose of this thread is moot (automating printing server side). It is possible to load the file via URLs using the following html code:
"<"body>
"<"OBJECT id="pdf"
type="application/pdf"
width=800
height=600 >
"<"param name="src" value="http://localhost/pdfs/vorder_nc.pdf"/>
"<"/OBJECT>
"<"script language="JavaScript">
function waitLoad()
setTimeout("printFile()",2000);
function printFile()
var objPdf = document.getElementById('pdf');
objPdf.PrintAllFit(1);
"<"/script>
"<"/body>
So, if I used php or some other scripting language on the server to fill in the name of the pdf, I can load it via a URL, wait a couple of seconds for it to load, and then print it without user interaction. I wish that the LoadFile method would load a URL so that when it returns, I know it is loaded and I don't have to put faith in a timer that may not be enough for a large file.
This is the situation I'm in. This way works but I don't like the timer. I'd rather have the plugin let me know when it's loaded. Is there another method that can help me do what I want?
Thank again.

Annotate pdf documents using the reader plugin in the browser

Is it possible to annotate pdf documents using the reader plugin in the browser?

Sorry I do not have answers, and do not know details of the Mac/Adobe plugins problems.
Conspiracy theorists may wonder whether Adobe is constantly reviewing cost/benefit of supporting various OS s & Browsers.
One may note
* Flash Ubuntu development has effectively ceased, with all support ceasing in a few years http://www.adobe.com/devnet/flashplatform/whitepapers/roadmap.html
* Firefox on Windows Flash11.3 et seq has had many problems, I certainly have not noticed Adobe rolling out rapid and successful fixes for those problems
* and Android support was dropped http://blogs.adobe.com/flashplayer/2012/06/flash-player-and-android-update.html

About Reader plugin license and fee

Hello.
I'm a software developer at a company.
Our company developed plugin for Acrobat and Reader for sale to our customers.
I found that Reader plugin needs license and annual fee.
Could you give how much is it costs? (annual fee).
The plugins features that we developed is that extract all text on an active document when printing
and save the text to file as a something.txt in local drive(C:\).
Is this feature of product includes DRM RIKLA structure?
And Is that different charge of fee than non-DRM product?
Thanks.

Also:
- to develop a Reader plug-in you must start with Acrobat
- Adobe only sometimes give permission for a Reader plug-in; the plug-in must suit their business aims
- the only way to find your fee is to apply. The fee is not the same for everyone.
- people do not need Reader plug-ins, because they can buy Acrobat. Part of the cost of the Reader plug-in fee is to make up for "lost" sales of Reader
- security plug-ins (DRM) are the most expensive, apparently $50,000 per year
- you will need to fully install and read many thousands of pages of documentation in the Acrobat SDK; there is a steep learning curve to write plug-ins.
- Reader plugins have many technical limitations e.g. cannot save files.

Queries around Adobe Reader Plugins

Hi,
I'm in the process of developing a plugin for adobe reader and was wondering if someone could help me clear the following doubts before I go ahead:
1. I want to add a new menu item to the Adobe Reader interface and launch another application when this menu item is clicked. Is this possible? Or are there any API restrictions?
2. If my plugin is going to be used within an organization, do I need separate keys for each employee? Is a key required per plugin or is it required per instance of the plugin?
3. What happens when the key expires? Do I get another key? Or is the same key renewed? Basically, I need to know if I will have to recompile and reinstall the plugin every time the key expires

Hi NiceNix,
Thanks for a quick reply and Solution. Yes their might be possibility of Key Getting corrupted. But before that i just need to make sure if I followed the correct steps while building the Reader Enable Plugin.
I have tried a BasicPlugin sample that there in the Adobe 8 SDK. Following are the steps I followed while developing a reader unable plug in. Can you please verify if the steps are correct?
1.In the sources folder of the sample I copied the Dummy.rc file and the Digital certificate file received from Adobe
2.Open the project in VS 2005, Added the existing rc files in the project
3.Build the Project
4.Run the Makemd32.exe specifying the plug-in name, path of key pair file and the digest file I need to generate (msgdig.rc)
5.In the resource view of the project , open the data portion of Dummy.rc file and replaced its API Encrypted data with the one from the msgdig file
6.Build the project ( Not rebuild All)
After following these steps I put the api file into the Plug-in folder of Adobe 8.0. Now, Whenever I open the Reader it gives a message saying Invalid Plug-in. Adobe will quit.
Also, I tired the BasciPlugin sample from Adobe 9 SDK and followed the same steps as above. Here it does not give the error but my Plug-in is not seen in any top menus of Reader.
Please let me know if I am missing out something.
Thanks and Regards,
Amruta Pawar

Reader plugin for Chrome versions 42+ no longer work

As of 04/15/2015, Google has deprecated the NPAPI which the Adobe Reader plugin apparently uses (see NPAPI deprecation: developer guide - The Chromium Projects) This means the Adobe Reader plugin for Chrome no longer works.
Does Adobe have any plans to provide a new plugin or extension for Chrome?
If not, what is an alternative that can handle .xdp forms? I've tried PDF Viewer (PDF.js), Notable PDF, and Xodo but none of them handle .xdp files.

All: I use the Adobe Reader plugin a lot for work. I have found a workaround to the new Chrome version 42 update that has removed the NPAPI plugins, including Adobe Reader.
In the Chrome browser URL, type "chrome://flags". Find the flag called "Enable NPAPI Mac, Windows" and click "Enable".
Then, go back to your plugins in Chrome, "chrome://plugins". Make sure the Adobe Reader plugin is Enabled and the Chrome PDF Viewer is disabled. Everything should work as it did before.

Deploying Adobe reader plugin not working

Hi
I have an adobe reader plugin that works on my development machine. It displayes the toolbar in the "Extended" tab. I copied the .api file onto the plugins folder on another machine but the extended tab does not display. I also copied this onto the plugins folder just to test and this works.
Does anyone have any ideas? Is there some place where it(adobe reader) logs errors?.

One of the limitations of plug-ins (in many apps) is that they tend to have to be developed in the same language as the host. Otherwise the cost of converting linkages makes plug-in performance unacceptable; similar to the reason 32-bit apps have 32-bit plug-ins and 64-bit apps have 64-bit plug-ins. Acrobat is written in C/C++, hence so are plug-ins. If Acrobat was ever written in C# (unlikely while it is also on Mac), then no doubt all the plug-ins in existence would need to be rewritten in C#.
Personally, having developed many and very large Acrobat plug-ins, I don't see that C# would be an advantage. Of course what is popular and what is marketed to developers is not always what is the most practical.

Permission to build read plugins

How does one get permission to develop plugins for Adobe reader as I can't find that information anywhere? Does one just develop reader plugins using the SDK and API or is there a special toolkit to purchase? Are royalties involved? Thank you

Javascript Access to Adobe Reader Plugin

This is more of a developer question but I thought I would give it a shot because I have yet to find any documentation.
Does Safari have scripting access to the Adobe Reader plugin?
The following works in IE because printWithDialog(); function is revealed to IE javascript when a PDF is embeded.
javascript:
var thePdf = document.getElementById("printFrame");
thePdf.printWithDialog();
embed in the body of the web page:
<embed height="400" width="370" name="printFrame" id="printFrame" src="theFile.pdf" />
Can I do something similiar in Safari?
Thank you,
-jscott

Yes it does. It works on the website I support. We do it thru a javascript popwin and it loads in all browsers.

How to reinstall Adobe Reader plugin?

Somehow Safari has lost its Reader plugin. Can somebody tell me how to put it back?
I still have Adobe Reader on my computer but when I click on a pdf link Safari now uses Preview again instead of Reader.
I already tried to download Reader and reinstall it but to no avail.
Many thanks for all your suggestions,
Eaglepeak

Check to see if the plugin is still in 'HD/Library/Internet Plug-ins/'. If it is, launch Adobe Reader and navigate to the 'internet' section of its preferences. Ensure that the plugin is enabled.

Does Adobe Reader plugin work in Firefox 11 if launched from Gnome?

Sorry to cross post, but I couldn't figure out how to move my post from the "Adobe Reader" forum to the "Adobe Reader for Unix" forum.
If I launch Firefox (version 11) from the command line (Linux shell), then I can open a PDF with the Adobe Reader plugin. But if I launch Firefox from the desktop or panel in Gnome, I get the message "Could not launch Adobe Reader 9.1.0. Please make sure it exists in PATH variable in the environment. If the problem persists, please reinstall the application."
acroread is in the PATH variable - I checked ("which acroread" and "echo $PATH")
We are using acroread 9.3.2. We tried updating to the latest acroread 9.4.something ...? but the SendMail option was missing from Edit->Preferences, so we reverted to 9.3.2.
We are using Debian Linux 5.0.8.
It is very convenient and user-friendly in our library for visitors to be able to view a PDF in the browser (with the plugin) and to be able to just click on the envelope icon from there to send a PDF.
This was working fine until we upgraded to Adobe Reader 9.4. We reverted to 9.3.2, and everything was working fine again. Then our systems people did some things, including updating Mozilla Firefox from version 3.6.13 to version 11. Then the plugin stopped working from the Gnome launch panel. I tried running the old Firefox 3.6.13 from the Gnome launch panel, but the plugin no longer works in it, either.
Has anyone had this problem?
Sometimes running Firefox from the command line gives some errors. I tried various versions of nppdf.so and tried toggling the about:config variable "dom.ipc.plugins.enabled.nppdf.so" but nothing changed.

I have the same or a very similar issue on WIn7 64bit
