Comparing document versions in Reader?

Can I compare two versions of the same pdf document and see the changes between versions in Reader?

Not in Reader, no.

Okay - just realised that the last screen was just asking for a "title" for my question!
I have Adobe Acrobat XI standard, but would like to trial the "compare documents" feature on Pro. I tried to download a trial version of Pro, but the installer indicated that "it detected a more fully featured version of the product" - presumably my standard version? - and stopped installation. It is not clear to me what my options are for either upgrading to Pro, or selectively purchasing the "compare documents" plugin (if possible). I am using what is presumably an Enterprise version of acrobat (i.e. my employer owns it, not me) - so not sure what limitations that results in. I think this is a simple question, but would be grateful for advice.

- You can't install Acrobat Pro alongside Acrobat Standard. You will need to remove Standard to be able to install Pro.
- You (probably) can't upgrade your license if it's a part of an enterprise license. The entire license will need to be upgraded.
- It's not possible to install just the "Compare Documents" function as a sort of add-on to Acrobat Standard.

Signing a document using a plugin in different versions of Reader

Hi,
I am signing a pdf document with my own .cer file using a plugin. Everything works great in Reader 8, I've got a green check, it specifies that this is a valid signature and I can view the certificate. In Reader 9, however, I receive a huge question mark, but it still specifies that the signature is valid and I can view the certificate. In Reader X, the signature is "UNKOWN".
How do I get rid of the question mark? Even if I delete the vector data for the drawing the question mark in the plugin, a big yellow question mark is still being displayed in Reader 9 and X.
Thank you,
Magda

Again, I know NOTHING about your plugin, your code, the certificate in question, etc.
The ONLY WAY to get you an answer is for you to provide our support staff with the PDF in question, at least as a starting point. Please open a support contract.

Why can't i see documents using adobe reader even though I have the most updated version?

Why can't I see documents using adobe reader even though I have the most updated version?

Hi lawalton,
Please tell me a bit more--what happens when you try to open your files in Reader? Are you getting an error message? Do they open, but don't display correctly?
I look forward to hearing back from you so we can get this mystery sorted out.

Compare Documents tool in Acrobat Pro 9

I'm assessing the Compare Documents tool in Acrobat Pro 9 for business use, and have some very specific questions about its functionality:
When I initially load a pair of PDFs to compare, occasionally Acrobat refuses to accept them as anything but "scanned documents" even though they are fully electronic-sourced PDFs created in, usually, Adobe illustrator. What are the specific criteria that cause Acrobat Pro to force the "scanned documents" type? Is it related to the presence of only "flattened"/"outlined" text instead of embedded fonts? Lack of layers? Some other graphical feature? How do the comparison parameters/performance change when the loaded docs are designated as scanned rather than one of the other types?
Second, when I've done a Compare on two nearly identical documents and then call up the "old and difference images" display - is there any way at all to manipulate this display? Some of my docs are large - potentially full press-sheet size of around 24" x 40", and when the differences between them are tiny (e.g., a change in only a few Braille dots over the entire graphic) the on-screen rendering of the "difference image" side of the display is relatively tiny and practically useless, although it contains exactly the information I need to see. Can it be grabbed/stretched/magnified/saved/printed/analyzed some other way besides how it is? It seems to disappear literally at the first mouse-motion or key-touch, which is incredibly frustrating. Are there any changes or improvements in this feature in version 10.x over version 9.2.0 (which is the latest version my company has approved)?
Third, also at the post-compare stage, the feature tags a small printer info block in a corner of the document with "This image was replaced" even when I know the info block has not been changed. Why could this happen?

Sounds like you want to do this on a server, but you should know that Adobe Acrobat cannot legally be used on a server.
For server-based PDF operations you can look at Adobe LiveCycle products or our Adobe PDFLibrary (available in both Java and C++)

Comparing Documents | Acrobat X | Adobe TV

This video details using the Compare Documents command in Acrobat X Pro. to identify what has changed between two versions of a PDF file.
http://adobe.ly/A1ANdu

Thanks for that, but if we have a large document in which there are only a few differences, is there any mechanism to easily find each difference, or look at ONLY the differences? It offers a link on the first page to the "first" difference, but after that, it seems we have to eyeball the document or compare panel to find any other differences. Again, in a large document with few differences, that's painful (and risky, if spotting any changes are critical).
I've also looked in the help and now am looking to see if other resources discussing PDF compare might show it. Thanks for any thoughts.

Can not compare documents

Hi, I just found out that you can compare documents in Acrobat. By problem is that I have two versions of a document that I would like to compare in Adobe Acrobat Pro 9. But when I go to > Document > Compare Documents it comes up with an error message:
“These documents have security settings which prevent comparison. Please modify the security settings to allow editing and try again.”
In both documents I have gone to > Advanced > Security > Show Security Properties; but the both show in the Security Tab “No Security” in the Security Method and everything is “Allowed” in the document restrictions part.
What other security settings would this error message be talking about?
Thanks in advance

I have the same trouble when I compare secured documents. I have received the documents from other person who has secured the documents and I can not change the settings.
So, how to compare secured documents? I see no reason why to prevent comparison because I do not edit them, only compare.

Comparing documents and false positives

Hello,
I often have to send a proof of a book to a printer. The proof is a PDF. When they return a soft proof--another PDF that they will use to print--I need to quickly compare the two to make sure that there have been no changes in the text.
The Compare Documents feature certainly beats a side-by-side eyeball scan. But I often get a lot of false positives, words are flagged that actually have not changed.
It appears that my PDF, exported from InDesign has some hidden discretionary hyphens. In ID these are used to make sure a word breaks at the end of the line at the correct syllable. They are invisible when printed. In a PDF these are not necessary because the text ain't gonna reflow, right?
But when I compare the soft proof to the original PDF, words with discretionary hyphens are flagged. Somehow the printer has stripped the discretionary hyphens. That's fine but what must I do to get rid of them in my PDF?
Below is an example. The PDF shown is the one from the printer. The comment box shows the difference from the original PDF, though there is in fact no difference on the page.
Any advice would be appreciated.
Tom

I like Acrobat's text comparisons, which have saved me from bad goofs several times -- mostly stray key-strokes, but once I caught an InDesign footnote numbering snafu. However, the false positives have always been annoying even without flagging every single discretionary hyphen.
I imagine you have tried the image method for comparisons, a modern version of the old trick of putting printouts of the old and new versions of a page on a light table to find differences.
I don't recall seeing comments of the type "undefined", but does re-sorting comments by type at least isolate these so you can step through the rest? I'm no scripter, but can a javascript mark or eliminate comments containing hyphens?
More drastic, would it be worth trying to eliminate the discretionary hyphens? For instance, you could apply Harb's "Freeze Composition" in InDesign, and then search-and-replace all discretionary hyphens. (Read the comments on the In-Tools site, as well as those in the InDesignSecrets blog it links to because you might want to modify the way it handles hyphens.)
Good luck!
David

How do I compare documents in Pages (they way you can do it, with redline, in Word)?

Hi, I'm trying to compare two versions of a document and need to see a redline, but can't seem to figure out if this is possible in Pages. Any ideas?

Pages ABSOLUTELY has a track changes feature, and it ABSOLUTELY shows track changes when an MS Word doc is opened. It does not automatically accept them, either.
Now... I wish someone could tell me how to combine a version of a doc without track changes on, with a prior version that has track changes on (someone sent me a final doc and forgot to leave the tracking on!)

Comparing documents in Pages?

Hello,
How do I compare 2 versions of a word document in Pages to see the differences? (Alternatively, is there any way to do this using the terminal?) Please help!
Thanks in advance!
Lali

Hello
given the structure of a Pages document:
a -- a subfolder named Contents and an other one named QuickLook.
b -- several picture files corresponding to images inserted in the document.
When the doc is in good health, double clicking these files open them in their creation application.
c -- index.xml.gz which is a packed version of the XML file describing our document.
If we double click it, it expands as index.xml which may be read in any XML aware application.
I assumes that comparison requires that the packed xml files are expanded then you would be able to compare the XML files themselves.

The loss of functionality of Compare Documents in Acrobat.

The Compare Documents function in Acrobat 9 is now useless to my department. I am currently a Graphic Designer/ Tech Writer who writes operator manuals and had always used Compare Documents function to find the differences in the documents (mostly textual differences). Then we updated and lost this functionality altogether. Now, the only comparison option allowed is "Scanned Documents," which treats the documents as pictures and only looks for the differences of the over-all page. I would like the old textual comparison function restored. I would have mentioned something sooner, but I was hoping this was just an accident and would be fixed in a future patch

This would be better handled in the Acrobat forum. The compare document works more effectively now that you are given three choice:
You choose if the documents are (a) Reports, spreadsheets, magazine layouts, (b) Presentation decks, drawings, or illustrations, or scanned documents. You are not limited to scanned documents. If that is all you are seeing please repost in the Acrobat Windows or Acrobat Mac forum, report your version of Acrobat, your OS, and perhaps a screen shot of what you are seeing. Note, I get three options as above and I am not restricted to Scanned documents.

I have Adobe Acrobat XI (ver 11.0.07). Adobe Help instructs me to find the document comparison command at "View Compare Documents," however, this command does exist on my screen. My View drop-down list does not include a command for Compare Documents.

What version of Acrobat do you have? This feature is only available in the Pro version, not in the Standard version.

Acrobat X "Compare Documents" Function Failing on Large / Complex PDFs

To all,
Upon initial testing, we were successful using the Compare Documents function on complex test files: two versions of an automotive wiring diagram. However, when attempting to compare two versions of a section from an automotive service repair manual (includes textual and graphical content), we receive ana error message "Operation Not Permitted." We are aware of the 250 page limitation and ability to select option "Text Only," but the document we are testing now is only 56 pages. Any thoughts / suggestions as to how we can alleviate this issue? Your input appreciated. Thanks!

@CtDave. I have gone back and checked the reduced versions and they have the same embedded fonts that the original and unreduced documents have. Please see the pics below. Thanks for any/all help!

Is there a way to comment on specific Document Version?

I have high hopes for document versioning. However, I can't find much information on the details. I'd like to understand how it works a little bit better. I have lots of questions. But the first thing that came to my attention is that to be really useful, I would need to make comments for a specific version. If I make a fundimental change in the document, I'd like to be able to make a comment about that version. Otherwise, I have to visually inspect the documents to see what version I need to restore. When working with very complex documents, it is very hard to visually inspect for that meaningful change.
Also, I would really like to read up on how versions work and documents behave. For instance, what is the significance of moving the file or copying the file. When does the versioning remain intact and when will it be left behind. I'd really appriciate if somebody could point me to any documentation or in depth review of the document versioning feature in Mountain Lion.
Thanks,

Apple hasn't posted much besides this: OS X Lion: About Auto Save and Versions.
There are some independent reviews such as: Mac OS X 10.7 Lion: the Ars Technica review. Scroll down to the contents for the section on Document revisions.
Bottom line -- because it only saves the previous contents of changed "chunks," you can't alter an existing Version; just make a new one.
Note that the actual file contains only the current contents; all the versions info is in a hidden, protected database. So when you move, copy, back-up, or send a file, only the current version goes with it.

How do I accept/reject green/red changes in a FM CMP Compare Document

I am working in FM 11 and needed to merge one file that two writers worked on at the same time with different sections of that file updated. I used the FM Utility > Compare Documents. The result CMP file showed me the inserted text in bright green and the deleted text in red. How do you accept/reject these changes? My workaround is to retype what I wanted to keep and select and delete text I wanted to delete.
I also tried to use SVN update to merge the files, but SVN didn't seem to be able to merge my two files (even though SVN merged a text file that user 1 UPDATED before they COMMITTED their change. The UPDATE merged the changes from writer 1 to the working copy from writer 2 without disturbing writer 2's changes. Then writer 2 was able to COMMIT. But this only worked on a TXT file and did not work with FM files. With FM, SVN just would not let writer 2 UPDATE if his copy was not in sync with the committed copy.
Ideally I would like to be able to merge changes on the same file from two writers who updated different sections. Any suggestions? Thanks.

Another approach:
FrameMaker uses the conditions Inserted and Deleted to mark inserted and deleted text in the CMP file.
In the Search/Replace dialog select the Deleted condition for deleted text to search for.
Leave the Replace box empty.
Then search for the Deleted condition and either replace (i.e. delete the text) or leave it as it is.
After this search/replace the remaining text with the Deleted condition is correct. Therefore delete this condition without deleting the text.
Then do the same with the Inserted condition for inserted text. Either delete this text or leave it as it is.
Then delete this Inserted condition.
