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.

How to get image properties in PDF using javascript or plug ins

Hi
How to get the image(all the images) properties in PDF using javascript or suggest plug ins
Thanks in Advance

HI,
In the PDF Edit API's ( as has already been suggested) there is the PDEImage and using this you should be able to find out everything you need to know about any image in a PDF file.
I would recommend starting with PDEImageGetAttrs
Hope this helps

Accessing Txt in Image on Text pdf file

Use Omnipage OCR s/w to produce pdf Image on Text (i-o-t) pdf files. Sometimes I miss a correction I wd like to have made. If I correct this via Omnipage I then must re-insert the corrected pdf page into a by-now completed pdf document file which is all a bit time-consuming.
Is there any way I can use Acrobat directly to read the text component of the image on Text pdf file and correct the underlying text there?
Am using Acrobat 5; is this feature available in a later version of Acrobat?

If you can use the touchup text tool, then it is possible. You can not re OCR the page what has text on it.

How do I hide the file names/path names of embedded images in a PDF document?

I created a PDF document from a Word document, and the problem is that the PDF document shows the file names and path names for all of the embedded images in the PDF document. I don't want that information displayed. I don't want to send the PDF out to clients and have them read the names I've assigned to those images, plus it looks messy. And I've lost many of the original image files so they only exist in the Word document, thus I can't go back and rename them. I searched the internet for an answer but I couldn't find one anywhere.

When you create a tagged (accessible) PDF file from Word, placed bitmap images will use their filename as the "ALT text" if you don't define something else for the text to say, because an image without any ALT text is a failure against the accessibility standards. You can't change that default action, so you should put your own meaningful text into the ALT field for each image - which is what you should be doing anyway if the PDF is standards-compliant.
You can can set the text in Word, but it depends on your version as to where the dialogs are - Google for it - or you can change/delete it in Acrobat using the tags navigation pane on the left side of the window (right-click the sidebar if it's not visible). Drill down through the tags structure to find the "<Figure>" tag you want to change, right-click and choose Properties, then put something in the "Alternative text" field. This process isn't something you can easily automate, but if you don't need tags at all, you can save without tags (or print to PDF).

InDesign equivalent of LiveCycle's "Image Field" in PDF form creation?

LiveCycle has a PDF form field called "Image Field". We add this field to the PDF files we create so that our end users can select and import a JPEG image into their PDF document using Adobe Reader.
Now we would like to use InDesign to produce the same PDF form files as an alternative to using LiveCycle. Does InDesign have a PDF form field like LiveCycle's "Image Field"? We haven't found it yet.
In other words, does someone know in InDesign how to create a field in PDF forms which has the same functionality as LiveCycle's "Image Field"? LiveCycle's field works in enabled Adobe Reader files, and permits JPEG format, among others.
Thank you,
Kevin
P.S. We discovered a way to create PDF forms in Adobe Acrobat Pro XI with similar functionality by using JavaScript, but the Acrobat Pro created documents only permit Adobe Reader to import PDF files, not JPEG or other image formats. So Adobe Acrobat Pro XI was not a viable alternative to LiveCycle for creating our PDF files. We'd like to know if we need to rule out InDesign, too.

It's worth separating out the different responsibilities and products.
Whether a functionality exists in Reader depends on the Acrobat team. Reader, being free, is limited by design, the aim of the design being to sell copies of Acrobat. Obviously, Reader can't make PDFs or do preflighting. Less obviously, there are a bunch of JavaScript functions that don't work. Sometimes, with Reader enabling, more functions become available. (There are different kinds of Reader enabling, some of which need very expensive extra products).
Whether a form capability exists at all is largely down to the PDF specification (now an ISO standard) or the XFA specification. Adobe can choose to go beyond the specification but largely choose not to.
So, the InDesign team can make form fields, not because the Acrobat team approves, but because the way this is done is written down in the PDF Specification. InDesign _could_ choose to make XFA forms, but thank goodness that will never happen.
So, if you want InDesign forms to do something you first have to ask: can Acrobat forms to this. NOT XFA (LIveCycle forms) which are done by a different team to different rules. So far as I know Acrobat forms cannot do the sort of thing you want; that is, placing arbitrary graphics, but in certain circumstances they can place PDF files.
Why make the distinction?
- If Acrobat can make forms that do this, then so can InDesign: it's worth asking the InDesign people to do it.
- If Adobe limit Adobe Reader, there is no use asking the InDesign team to solve this.
- If Acrobat can't make forms that do this, then nor can InDesign.

Is it possible to submit an image file with PDF form?

Hello,
I know that Acrobat does not offer a field for image file submission.
whether there are workarounds to solve this problem?
I have found suggestions regarding place an image to button icon:
event.target.buttonImportIcon();
but I can't understand is it possible to submit this image to server (Reader supports PDF only).
Any advices?
Yury

Hi Yury,
Yes, that's correct you can create a button and add a script to it that would prompt the user to select an image file when that button is clicked. Then that image can be displayed using the same button (buttons can show either an image or text).
The script in question is:
event.target.buttonImportIcon();
You need to add it as an Run a JavaScript-action to your button, triggered by the MouseUp event, and of course set the button's layout.
Please refer to this link : https://acrobatusers.com/tutorials/how-to-create-a-button-form-field-to-insert-a-pdf-file
On submitting the image it gets embedded with the PDF.
If the users are using Acrobat they will be able to view the image in the PDF, however if they are using only Reader, you will have to create the form using LiveCycle & then save it in a Reader Extendable Format.
Regards,
Aadesh

I have to make inaccessible the Javascript code embedded in a form pdf. How can I do?

You can secure the file and prevent access to the code, but it's very easy
to overcome that. Alternatively you can use a code obfuscator to make the
code less legible.

How To Access JSP Image file Path inside JavaBean Class

In my Webapplication,i have jsp and javabeans files. i need to send one image file path contains in Image folder to JavaBean[MyBean.java].
From MyBean i am trying to display that image using PdfGen Application[JAR] in a new PDF Document.
The Web Application Structure is as
MyWebApp
Image
\ mypic.gif
JSP
\myjsp.jsp
WEB-INF
classes
\pack.MyBean.java
My Question :
Inside the webapplication[JSP] the image file is accessed as a URL.(like http://localhost:7001/mywebapp/Image/mypic.gif). but From JavaBean: How To access this file? becz inside javabean it needs a complete system path..How to solve this problem? plz send me any solutions related to my problem....Thank U.

Dear Madruguinha!
Thank you very much for your tips.
but i find another one method for accessing the image.
// Inside Servlet or JSP
String realPath=getServletContext().getRealPath("Image"+"/pic1.gif");
Now we can send this exact system path variable to any java beans or java class that needs the image path as "drivename:\foldername\filename" like "c:\myflolder\mypic.gif" and not web context path.

Why do images within a PDF look jagged when viewed in Acrobat Pro 10.1.6?

Using a MacBook Pro running Mac OS version 10.7.5 with NVIDIA GeForce GT 650M 1024 MB graphics card. High-resolution source images look fine in other software, and embedded images in a PDF look fine when viewed on Google Drive, but curves and diagonal lines look jagged when viewed in Acrobat Pro 10.1.6. Checking smoothing options in Preferences only adjusts the position of the jagged edges; it neither enhances nor ameliorates them.
I created a sample PDF to illustrate the problem I'm having. Created in illustrator, exported to PNG and converted to PDF. Here is a screenshot of the source PNG side-by-side with the PDF I created from it:
Please note that when I preview the PDF in Finder, and when I view the PDF in Chrome using Google Drive, the image looks fine. Here's a link to the sample PDF:
http://www.sendspace.com/file/77f5m6
Any assistance is appreciated. Thanks!

Unfortunately, as I mentioned in my original post, I've already tried toggling smoothing options. They don't make the jagged edges go away—they just change them slightly. In some cases, as with the sample file provided, it does help smooth the art out, but it never looks as good as it did going in, in a recent project, toggling smoothing options didn't affect the appearance of the image at all. Zoom does not appear to relieve the artifacting.
A little clarification: this PDF was created from a flat PNG, but I have had this issue with PNGs and TIFFs as well, generated by both Photoshop and Illustrator. To reiterate, the PDFs display fine in other software—Finder preview looks great, and the same file viewed in my browser via Google Drive looks as intended as well. A colleague was able to replicate this issue in Acrobat on his Windows machine. This appears to be a rendering issue specific to Acrobat with regards to the files I use it to create.

BMP image?
Or Is it possible to insert any text instead of image?
But I need to work just like the stamper sample present in sdk. that is when i click on the pdf document any text has to be inserted instead of the image. I should not be to type the text in the pdf, but it should work exactly similiar to the stamper sample, but text has to be inserted instead of an image.
How can this be done? Is it possible to do?
Please help.

Figuring out how to extract images from a PDF file

Hi,
I'm trying to write a small app that extracts all images from a PDF file. I already wrote a nice parser and it works good but the only problem is that I can't quite figure out from the reference how to decode all images in a PDF file to normal files such as tiffs, jpegs, bmps etc. For now I'm focusing on XObject images and not dealing with inline images.
From what I understand so far just by trying and looking at open sources I figured that if I see a XObject Image with a DCTDecode filter, taking the stream data without doing anything to it and saving it as a jpeg file works. But doing the same to FlateDecoded streams or CCITTFax didn't work.
What is the right way to properly extract the images?

In general you have to
* decode the stream
* extract the pixel data
* use ColorSpace, BitsPerComponent, Decode and Width to unpack pixel
values
* reconstruct an image file format according to its specification
There are no other shortcuts. The DCTDecode shortcut (which doesn't
work for CMYK JPEG files) is just a piece of fantastic good luck.

How can I create an iBook using iBooks Author using images from a PDF?

I have a complex book with custom fonts and lots of images, and the client wants it on the iPad. So my most reasonable option seems to be to take images from a PDF and use them for the pages. However, images in iBook Author don't get "laid out" as expected in Portrait mode. How can I create a layout that is essentially one image per page in portrait mode, and then convert that to landscape mode? Or is there an easier way to go about this?

tk0us wrote:
Make sure you have disabled portrait in the Inspector.
I don't understand why portrait mode defaults images and other "widgets" to thumbnails. The original format of the book (and of 99% of all books I'm guessing) is in portrait format. By forcing the book to work only in landscape mode it's forcing the page image to be half the size, and that makes using this book particularly difficult. Is there no way to force the pages to be full-size in portrait mode?

Saving multiple images from a PDF to use later

How can I save individual images from a PDF to use later? I would like to be able to save them in a separate folder?

When you open the pdf, you'll see the import pdf window. Just click the Images radio button, then select the images you want to open in PSE, and then save them in the editor:

When I try to print an jpeg or png from Photoshop all it does is convert the image to a PDF & plop it on my desktop- it won't print the image. Any suggestions as to how to fix this?

Yes, the printer is on, it’s selected in Printer Set-Up & I’ve never had this problem before. It’s definitely a Photoshop issue as every other type of file prints fine. I’ve uninstalled Pshop & am now reinstalling. Hope that will do the trick.
