Protect images / content in PDF...

Hi,
How can I set up securities to protect copying of images / general content of a PDF? I went through the settings in Acrobat, but could not find what the name of this feature is.
Thanks!

OK, when you mention password security, I am wondering at what point would the file prompt for a password? Only if trying to open in an application other than Acrobat?
When?
Thanks. As the other person mentioned, it's probably not worth doing this seeing as it can be cracked with a little effort.

Change images/content within PDF using controls?

Hi,
Sorry about the title of the question -- not sure how to phrase it. Basically I need to know:
Is it possible, within a PDF, to give the viewer an option to switch content using a dropdown list, or radio buttons or some other form of control.
So, lets say I have an image on the pdf, and a drop-down next to it. If the user pick 'A' from the drop-down, they get one image, if 'B' another. Similar thing for a piece of text.
Is this something that can be done (HOW it could be done that would be awesome to know also : ) ?
A similar side-question:
Is it possible to allow a user to "upload" an image into a pdf? Something like having a placeholder for an image on the PDF, and an UPLOAD button, that lets the user browse for an image, which will then go into the placeholder (and made to fit). Is this possible?
Thanks in advance for any info,
Andrey

Hey Data_bitz
Let me see if I understand correctly:
Content is in Workflow A.
Exception occurs the content goes to another workflow (or step) assigned to the "exception" alias.
Now you want the members of the exception alias to figure out where the content should really go and reroute it to that workflow.
Is that right?
There are a number of ways to do this but here is one using sub workflows and jumps.
If so you should do the following
Workflow A = step 1.. step N, exception step, final step, exit
In the exception step entry event check for the custom metadata field value. If present, stay in the step, if absent or set to some automatic default, skip the exception step and continue to final step.
In the exception step update event check for a custom metadata field value that indicates what exception resolution workflow the content should go into.
Have a jump defined for each exception resolution workflow and a return step that comes back to the final step of Workflow A (that last return step is optional).
The idea is that your exception managers (members of your exception alias take a look at the content, figure out what workflow is needed, select the workflow from a metadata option list that only appears when the doc is in workflow (you do this with profiles), and effectively "assign" it to the users in that particular exception resolution workflow.
You really do not want to be changing security groups in the middle of a workflow as it breaks the security paradigm of the document.
hope this helps!

CMYK image in a PDF is involuntarily converted to RGB when you send from Acrobat Pro DC to Photoshop for editing

Hi,
When I send a CMYK image from Adobe Acrobat Pro DC to Photoshop CC 2014 to be edited, it opens up as RGB in Photoshop CC 2014. If I do the same with Adobe Acrobat XI on another machine, the image opens as CMYK, as it should normally do. As we had created the print-ready PDF in the first place, we know that the image is definitely CMYK and is properly opened in Photoshop if we use Adoba Acrobat Pro XI. We of course can go back to the original document and edit the linked image and re-export a new PDF. But on many occasions we need to do last minute corrections on images by editing them externally in Photoshop.
Best,
Refik Telhan

It's really necessary to know by which program you had created the PDF.
Here comes a test PDF for questions like yours, created by InDesign:
http://docs-hoffmann.de/riptest05072013.pdf
Different images:
sRGB, pRGB=ProphotoRGB, CMYK , all with individually embedded profile,
Grayscales: without embedded profiles, because InDesign doesn't embed gray profiles,
Lab: without profile, because Lab is automatically detected and not ambiguuos.
Of course, using so many different images in one PDF is useful only for tests.
An actual test:
Touch Up Object Grayscale and edit in Photoshop. There is no embedded profile
but the image is in PS detected as Grayscale. One has to assign a profile.
Re-imported in the doc, it is a Grayscale JPEG*, before it was a Grayscale ZIP.
In Acrobat 8 one can check the actual content of a PDF by
Advanced > Print Production > Preflight
In newer versions this is still available but somewhere else.
I'm using version 8, because I uninstalled X on purpose.
Best regards --Gernot Hoffmann
*Edited:
As far as I remember, there is no special code for Grayscale JPEGs, it's just a JPEG
with zeros in the Cb Cr channels ... like an R=G=B gray image.

How can I make the bleed image content reappear in indesign cs6

Hi there,
I created a 3mm bleed in the document setup and made sure the artwork filled the bleed area. Then, suddenly, after playing around with some view settings (and maybe some other things that i cant remember), the bleed image content will not show up in neither indesign nor the exported pdf. When I set the view mode to normal, it just shows the bleed content area as white. I see the bleed lines and see that the images are filling the bleed when selecting the images themselves, but the bleed area is completely white and I can´t send my files to the printer as the content will not show up there either.
Has anyone experienced this and know a fix? I was thinking that maybe the reset preferences would help, but I´m unsure.
Grateful for any help
Lise

Hi Larry,
I am in Normal mode and yes, the W shortcut toggle works.

Javascript access to images in a PDF

Hello,
i'm a newbie to javascripting adobe apps, so i hope you'll excuse me if the question is just too stupid...
I need to open in photoshop all the images in a pdf document. The pdf doc is singlepaged, usually with a single image (it's a adverting page in a magazine). When I have to do a quick retouch on a image, i choose Touchup Object, select the image, right click and choose Modify Image (actually I am using Acrobat in Italian: i hope the traslation makes sense) and Photoshop pops up. I modify the image and save it.
Is it possible to script this process?
My basic question actually is: how do i have access to the image in the pdf document? Exploring the contents of the pdf I see the image is in a XObject: can i get to it via javascript?
any help is really appreciated! thanks
Mauroo

What you're trying to do requires a plug-in written in C/C++. It cannot be accomplished with Acrobat JavaScript.

Why can't I replace an image in a PDF with an EPS file?

I've never seen this behavior before. When I browse out to get some EPS files, they're all greyed out!!! The only files I can import in place of an exsiting image are TIFFs and PNGs, bitmap image formats. This is ridiculous.
Thanks,
Peter

It would be part of a different scenario that goes something like this:
1. Delete the original image in Acrobat (e.g., with the TouchUp Object tool, or whatever your version of Acrobat calls it).
2. Add a button in Acrobat and set up the properties as you want.
   a. Layout: Icon Only
   b. No visible background or border
   c. Line style: Solid
   d. Set the scaling you want
   e. Whatever else
3. On the Options tab of the Field Properties dialog, click the "Select Icon" button and choose a page from the PDF that has the content you want to use. EPS/Postscript is an option, but you may want to convert to PDF first to make sure everything is as you want it.
4. Flatten the button to convert its appearance to regular page contents.
The vector (and text and image) content of the PDF/EPS will be preserved, and can be scaled to fit the area defined by the button boundaries.
You can preconfigue a button with all of the properties set up as you want them, and simply copy & paste it whenever you need to do this, saving a bit of time.

Protecting images in slideshow from being copied

Hi, I am new to iDVD and would like to know....
Would a client be able to print from images that I have made into a slideshow using iDVD.
If this is possible how can I protect my images?
John

Hello John,
the short answer is: No.
There is no possibility in iDVD (or DVD Studio Pro,
for that matter) to effectively protect the contents
of a DVD. The industry has been trying for a long
time to protect CDs & DVDs, but there are a lot of
tools freely available on the Net that break these
protections, be that illegal or not.
What you can do is place a watermark (logo/© 2006 by
John) on your pics. This can be done in Photoshop or
iWatermark for example. The drawback is that you need
to place the watermark in a way that it doesn't
interfere with viewing, thus it would be easy to
simply cut the part.
Final thought: the "ripping" of a DVD rarely produces
good quality results, as the MPEG-2 encoded video is
not meant to be edited further. So your client might
not get the hi-res prints he/she expects.
hope this helps
mish
Thanks Mish. I will resort to using a watermark.
Could you advise on the resolution of jpegs to use for a slideshow?

Need help urgently with conversion of tiff images(.odm) to pdf files...

Hi Friends!!
Currently we are working on a project which involves conversion of tiff image files to Pdf files. We are able to convert .tif files to .pdf files.(We are using iText libraries for this..)
But the only problem we are facing is ---
We have some .odm files which are multipage tiff files. But we are unable to convert them into .pdf files.
Note:- Please note .odm is a proprietary extension given by Optix Document Management and Workflow Systems. We figured out that .odm works as a collection of .tif images.
I searched a lot on the net but couldn't find any help, so, if anyone has any idea of how to go about doing this please let me know...
Please email any suggestions to [email protected]
Thanks in advance for your help,
Rita

I'm afraid I can't help much with your problem, but I think I can offer some advice on how to get better, faster answers here at this forum:
First, don't flag your question as urgent, even if it is for you. Claiming urgency is very likely to be counter-productive: most forum regulars will simply ignore such messages as rude and selfish attempts to elicit immediate and special attention.
Besides, unless the Symbionese Liberation Army is about to chase you over the edge of a cliff, your problem probably isn't as urgent as you think. :o)
Second, don't ask people to reply by private email. Most Forum regulars believe solving problems should be a public, transparent process during which a first try at an answer can and should be corrected if someone more knowledgeable notices that it is incomplete or incorrect. Also, they get some of their reward for being respondents from being seen to be competent and knowledgeable by their peers (not to mention the possibility of collecting some of those precious Duke Dollars).
Good luck!

Image inside of PDF file?

I am creating a .bmp file in Photoshop and inserting it into a word document. I then save that image as a .pdf. When viewing pdf and hovering your cursor over the image inside the .pdf, the name of the image file appears(like a text tool tip). Is there a way to prevent this from happening?
Thanks

PDF Optimizer - Perhaps not available in Standard.
Look for it under the 'Advanced' menu drop-down.
When Acrobat supported file formats are brought into PDF with Acrobat (PDFMaker) many have configuration options associated with their "Convert to PDF".
A supported graphics file format, by itself or if in an authoring file (FM, DOC, etc.) will be 'touched' by these.
Open Acrobat's Preferences. Select the Category "Convert To PDF". Scroll down the center pane's listing of file formats. Locate and select PNG. Click the 'Edit' button. Some configuration options for compression and color management are provided. You could play with these.
HOWEVER -
The Word to PDF process would have to be via PDFMaker (Convert... from the Acrobat Bar) and *not* via Save As PDF-XPS. The MS Office routine does not provide the functionality described above for Acrobat. The Office process is completely separate from anything "Adobe" or "Acrobat".
Also, something described often by Bill@VT -- Word, particular 2007, 2010 seems to do some 'odd' things to graphics in a Word file that is going to anything other than a piece of paper.
Some folks seem to get satisfactory behavior by use of EPS.
Also, it may be worth playing with a JPEG of the logo.
About the PDF.
From what you describe it seems that you have a web link, in the PDF, to the stand alone PNG. This would permit separate download of the PNG.
I suspect that Acrobat Standard 9.x does not provide the tool set available in Pro or Pro Extended. So, you'd not be able to edit/delete the web link (or link) in the PDF.
Perhaps, back in Word you have a 'Hyperlink' present that can be edited/removed?
Also, in Word, try an "import" - browse to file - select - make it an integral part of the Word file. Then produce the PDF.
Fundamentally, the PDF reflects the content mastered in the Word file. The Office Save As PDF-XPS or the Adobe PDFMaker merely process this out with whatever configuration option settings each provides.
Be well...

Insert image into a .pdf using InDesign

Can I insert image into a .pdf using InDesign....

You can place a PDF as an image in InDesign, then add more content and export a new PDF.
There are also commercial plugins available that will allow you to open a PDF as editable objects in InDesign.

Password protecting and encrypting received pdf file

Hello there,
how can I password protect (and encrypt) a pdf file that I received from someone else? For example, I may get a copy of my tax return from my accountant that I don't want anyone else to see on my computer or when I back up contents of my computer online.
I have only Adobe Reader 8 installed on my computer. So I am not writing these pdf files myself - I realize that then I would have full control over the security settings.
Microsoft Word and Excel files I can password protect. How can I do this for "received pdf files"?
Thank you for your help.

You need Acrobat, not Reader.
Be aware that even then, PDF security is easy to bypass.
I use a Mac for the most part but isn't there any features in Windows that will allow you to protect folders?

How-to protect static content

Hi !
I have a site with many files (pictures, XML files, etc)
How can I protect those content from unauthorized access / sniff ?
I was thinking in two options
1) a filter servlet, validating sessions permissions etc
2) a servlet to write out the files (...)
Any other suggestion? best practice?
Regards
Joe

Actually yes each server has its own realm implementation but it is all configured and handled by the server and does not affect the portability of the application.
How to protect the static pages is dependant on how you allow access to your web application.
If you don't have any security in the web app you then put any files that you don't want accessed in the browser in the WEB-INF folder. Images and other files that are accessible in the browser you put in folders with an index page to prevent users from seeing the directory structure.
If your application uses server managed security you include you use this security to manage access to the files.
If you are using application based security then you go with a filter.
