Checking resolution in a PDF image

This might be more of an Acrobat question, but is there an easy way to check the resolution of an image that was done in Illustrator and is now sent to you as a PDF?
Thanks.

Thanks Monika and Jacob. The issue is that these files are created by outside sources in Illustrator and an image is dropped into the file. Usually it is embedded. At times the IL document is then made into a PDF and that is what we get. On the PDF, is there a good way to check the resolution. We have CS5, so I'm assuming if Illustrator editing capabilities are checked while making the PDF we can just open it in IL and check the images that way (Document info > Objects (or Embedded image). But what if the editing capabilities are not activated. Any way to check it then?
Thanks.

Script to check resolution of the embedded images in illustrator

Hi All,
Is there is any script available to check the resolution of the embedded image in the illustrator.

Hi Kenny,
I posted the following file to the NI outgoinng ftp site-- you'll have to grab it in the next few days before it gets automatically wiped off.
ftp.ni.com/outgoing/CompanyName.zip
Look for the "Using ResultsList Menus.doc" file in the main "CompanyName" folder, it will have installation instructions and step by step how-to-use information. Also feel free to email me with questions at [email protected]

Importing illustrator pdfs into photoshop sometimes won't allow me to open and check resolution?

Here's the scenario:
Customer sends me an illustrator file with an embedded image. I need to check the resolution of the image to see see if it is high resolution enough for print. I delete all art but the image in illustrator and then save that file as a pdf with the illustrator default.
I drag that pdf file into photoshop where I get the "Import PDF" dialog box. I know if I select the "Pages" button, then the resolution and color that appears in the dialog box are not the true specifications for the image. I have to select the "Images" button and open the file from there HOWEVER sometimes this option is not available and the "open" button is grayed out. I have yet to figure out why this happens on some of the pdf files I've saved from Illustrator.
This is the only way I have found to check resolutions on embedded files where I do not have the actual linked graphic. Does anyone have any ideas? Thanks for any help!

Just check the resolution in Illustrator instead of exporting a PDF to check in Photoshop.
If the image only is selected then the resolution is displayed in Control bar.
It may be in a nest of groups so either double-click repeatedly on the image until you've drilled down to it or select it in the Layers panel where the disclosure triangles will give access to it.

How to check the resolution of a pdf file using Acrobat 9 pro?

How to check the resolution of a pdf file using Acrobat 9 pro?

PDF files don't have one resolution, but may have none or many different resolutions, one per image. You can check the maximum/minimum resoluion with preflight in Acrobat Pro, but not in Adobe Reader.

How to reliably check the resolution for a pdf file?

Should I use preflight to reliably check the resolution for a pdf file? I have posted my frustrations on http://forums.adobe.com/thread/978098

You can create your own preflight tool to check for the dpi of embedded images.

Finding image resolution in a PDF?

I am currently working to perform some maintenance for an app that formats and resizes documents, usually PDFs. The problem happens when certain files are uploaded with an unusually large image resolution (according to the Preflight Properties, 2222.222/2222.222 pt/in). The documents with this resolution come in with file sizes of 36"x24" and end up formatted to 8.5"x11". This leaves the text and a lot of information unreadable.
I am using Visual Basic with iTextSharp to interact with the PDFs that come in. I'm able to find the width and height in points of the document without issue. Finding the image's width/height pixel count is what is giving me fits.
Is there any way in iTextSharp that I can determine the pixel count for the width/height of a PDF Image, or am I heading down a dead end street here?
Thanks in advance for any help you can provide.

I hate to reply again, but I'm still stuck. I've been through the SDK and documentation and have had no luck finding anything to help solve this problem. I don't really need to extract the image per se, I just need to find the resolution of it. Could you possibly point me in a definitive direction in the SDK/Documentation that I could use? There are a couple examples that deal with Preflight but none dealing with the image in the PDF or its properties.
Thanks in advance.

Custom book export resolution problem in PDF - only 150DPI!?

I've been using the custom book option and when it came to exporting my PDF I have run into a problem involving the undocumented output resolution of a PDF at a given size. The custom book dialog allows you to create a book with a certain size in inches, but this really has no real meaning since the resolution of that output cannot also be specified in either the layout option or the print dialog. For example is it 150dpi or 300dpi? From some investigation it appears to be locked at 150DPI.
Now I would have thought that Aperture was intelligent enough to just treat the album layout (this is my assumption) as some kind of smart object, where the layout is resolution independent and the final output resolution can be determined when printing to a printer or PDF. In that case the dialog for the setup of the custom size is correct. However, there is no option that I can see in the print dialog to actually specify the output resolution; Aperture is left to its own devices to specify an output resolution, which is undocumented.
I use a printer that accepts JPG or TIF files and I need 300dpi for an album size of 10x13 inches. This equates to 3900x3000 pixels per page. I am able to export to PDF in the print dialog and then used an automator action to export each page of the PDF as JPG and reimported back into Aperture 2 in the same action. In the PDF>JPG conversion option there is the ability to set the DPI to 300. That works fine and the resulting JPG images show as 300dpi (3900x3000px). When looking at the images though they look a little soft, which leads me to believe that my action was simply interpolating a 150dpi image in the PDF into 300dpi.
So to test this, I noticed that if I exported just one page of the album as a PDF and opened the PDF in Preview it does indeed tell you that it is 13x10 inches (no mention of the pixel resolution though). So, you can actually reimport a single page PDF into Aperture and if you do this it appears that the actual resolution is 1950x1500 and that equates to 150dpi for a 13x10 inch layout.
So there are two things that could possibly be going on here:
1. The actual layout of the album is locked at 150DPI and the save to PDF simply takes that and exports a PDF at that resolution.
2. The layout of the album is resolution independent, the size of the album (in the custom dialog) simply controls the aspect of the page layout, and the print dialog (save to PDF) is exporting as 150DPI as default. When I run my automator action (these are the Leopard PDF actions), the save each page to JPG action is up-res'ing the image to 300dpi.
This is where I need help. Is 1 or 2 (or something else?) happening. Also, does the PDF save as JPG12? That too is undocumented.
If number 1 is happening I may have to set my album size to 26x20inches to get a 10x13 inch page at 300dpi.
If number 2 is happening I need to find a PDF/TIFF/JPEG print driver to enable me to export at 300dpi as the print dialog in not standard (and we don't get the nice 'save as' drop down where we could do other things. So far my search has led me to CUPS-PDF, but that still doesn't allow for resolution to be set: http://www.codepoetry.net/projects/cups-pdf-for-mosx
Why can't Apple just figure this thing out correctly and allow the resolution to be specified by the user - what an oversight given all of the feedback requests for the custom album tool. We need 300dpi as a minimum as we can always down-res if we want.
Any ideas? I've got albums to send to clients! Help!
Thanks

When you import any PDF into Aperture, I think it rasterizes any PDF you import to a 150dpi flat image on import, even if it was a high res PDF to begin with. But theres the thing, PDFs don't have dpi (as such). Any shapes or text is a vector so don't have a DPI as they'll scale when printed. The images use their DPI when they were imported from the program that created the PDF.
So I did a quick test and put a page I made from Aperture in to Acrobat and ran a preflight check on all images to check the resolution. It came back at 349.956 ppi, so this example was over 350dpi.

Unable to display a PDF image on the page - Mac 10.6

Hi,
Running an iMac with 10.6.8 and Indesign 5.0.4. Just wanting to export a PDF as per usual via File > Export function. However, I keep getting the error message, "Unable to display a PDF image on the page'. No idea what this is and have never seen this error before. The only info on the internet reveals error code 0x2511(9489).
I've deleted prefs, closed down and re-opened Indesign and even restarted the computer. I've also re-linked the images contained in the document and even created a new document and set it up the same, but still the same problem. Investigating further, other Indesign documents still export properly.
The only ones that don't export are 2 documents, both giving this same error message. Both documents are ones where a client has sent a PDF, I've imported into two of these into an 2-page A4 Indesign document (each PDF is 48MB each) and then just added a text layer (using Times) which is properly installed on the computer. I basically have to 'update' course dates for the client and add PDF to the website, all very basic.
I've tried importing a jpeg and other PDFs into the file (replacing the existing ones) and they export fine.
All my software is legal and I've exported this document before now in exactly the same File > Export without any problems (under 10.5 and 10.6).
OK... I've just imported the offending PDFs into Acrobat, optimized and shrunk the file size, re-imported back to Indesign and the PDF export works fine. So it seems InDesign / PDF Export doesn't like large imported PDFs? I think they were originally exported from Publisher, so maybe that's the problem or a file conflict somehow.
Any ideas on the culprit? I've googled it, searched these forums and Apple discussions and haven't found anything. Although I've found a workaround, I do get large files to import and then export. Thanks for any help
Steve

It does sound like a problem with the original PDF files the client sent you. You can check how they were made in Acrobat Pro from the Additional MetaData button on the Description tab of the document properties dialog. It will be under Advanced at the bottom of the list when the metadata opens.
You might be able to salvage them by running the optimzer and not changing the size, or just doing a Save As in Acrobat.

Get resolution out of PDF page?

I have a PDF document that is created by creating NSImages with size in 72dpi pts, each has a single representation which is measured in pixels. I then put these images into PDFPages with initWithImage, and then save the document.
When I open the document, I need the resolution of the original image. However, all of the rectangles that PDFPage gives me are measured in points, not pixels.
I know that the information is in there, and I suppose I can try to parse the PDF data myself, by going through the voyeur.app example... but that's a WHOLE lot of effort to do something that should be pretty normal...
Is there an easier way to do this?

A PDF file is an end product, intended for sharing and distributing, but not
for editing. Editing should be done in the program that the file was
originally created in, before it is converted to PDF.
There are minor edits that can be done to a PDF file, but you described an
editing process that is just not possible in Acrobat.

How to retain focus in Web forms 6i item when displaying pdf image

How to retain focus in Web forms 6i item when displaying pdf image in a multi-record block?
Hello.
I have a Web Forms 6i program (version Forms 6.0.8.19.2) running in a 3-tier application. The web form program has a multi-record block containing invoices. When navigating to a record, the form should display the PDF invoice image which is stored in an Oracle 8.1.7 database as a BLOB in another window. When user press down-arrow, the next PDF invoice image should be displayed.
I am able to accomplish the functionality above by using web.show_document('URL', target') in the when-new-record-instance. The URL being called is a PL/SQL Web Toolkit stored procedure using wpg_docload.download_file built-in.
The problem is that the focus is lost on the Webform and the focus is shifted to the PDF image window when you navigate to the next record using down-arrow. I want to retain the focus in the form as this is a data-entry form, the operator will use down-arrow to go to the next-record rather than the mouse. I also only want to do this for this Invoice Entry form and NOT to all forms.
Please advise how to resolve this problem. Thank you.
Regards,
Armando

Magesh,
the issue of a SSO protected form showing the logon dialog is a knwon issue for Windows200 and the Oracle9iAS base release. If you applied Forms Patch 1 then this should be solved. Hope that I am right in that you are using Oracle9iAS and not Oracle9iDS. Do you see the Single Sign-On logon screen or the Forms logon dialog directly? Check the forms90.conf file in teh forms90/server directory as this contains the Form sso settings (mod_osso) which by default is commented out and therefore inactive. You need to remove the commenting '#' characters and make sure that each sentence having a '#' in front, after that starts on a new line.
The Forms deployment documentation within the Oracle9iAS docu provides this information too.

Extremely slow display of imported PDF images

We have been using imported PDF images in FrameMaker for many years now with great success. However, something happened a few weeks ago that now causes several of our machines to take an extremely long time to display PDF images. For example, a 200KB imported PDF image that previously took less than 1 second to render now takes 14 seconds. It is now almost impossible to work with many of our documents, which contains 100+ images.
This has happened on several of our PCs running FrameMaker 8 (via the TechComm suite). These machines have the following software configuration.
FrameMaker 8.0p277
Adobe Acrobat 8.1.3
Windows XP Professional SP3
We have also disabled all plugins, but there is no difference - the problem still persists.
However, there is one machine in our office that is not affected. It has the following configuration.
FrameMaker 8.0p277
Adobe Acrobat 7.1.0
Windows XP Professional SP3
Is it possible that Acrobat is affecting the PDF import? Or is it recent changes to XP? Or something that has been updated in the background?
Any assistance is greatly appreciated.

In practical terms, you can always toggle the display of graphics off in FM, but that doesn't work for all situations.
A few things to check:
Did you optimize the PDFs when they were created? (You'd still want to avoid downsampling and compression, but optimization still reduces the size.)
Also, a lot of the graphics processing is memory-intensive, so you should be using machines that are loaded up with RAM and have healthy open space.
Finally, if it happens consistently, the machines' anti-virus programs may be screening everything every time each file is opened. So adjust those settings... That's easy to test for too -- just shut it off and try an import.
How heavily are the servers being hit by other applications and users, and how fast is the network? Not being able to serve the files quickly enough is another chokepoint.
Move a book with Bruce Foster's Archive plugin to create a local copy and test with that to see if the problem is actually FM and the local machine, or something outside.....
It may also be worth checking to see if the computers have the lastest graphics card drivers loaded too.

Check resolution and clarity for sizing?

Hello - I have an issue where I print an image to a larger size, say 16x24 and the image in grainy. How do I check in LR3 what the image will look like at the enlarges size? I know there is a way!

You can't use your monitor to preview the printed output graininess of a photo because the Points Per Inch of a monitor is much lower then that of a printed output; Instead a bit of math will give you an indication of the graininess of a photo.
Divide the pixel width and height of the photo by the corresponding width and height of the intended printed output; take the smallest of these results and this will give you the Points Per Inch or PPI of the photo. For example, let's suppose that you have a 3000 pixel x 4000 pixel photo (approximately 12 Mega Pixel) and you want to output at 16 inches x 24 inches, then you would divide 3000/16=187.5 and 4000/24=166.66 so you maximum resolution given these numbers would be 166 PPI.
Typically good quality is achieved between 240 and 300 PPI but this also depends on the intended viewing distance; the further the viewing distance the lower the tolerance on PPI and the closer the viewing distance the higher the PPI should be; magazines are printed at much more then 300PPI while posters on a building may be printed at less then 100PPI.
You can tell Lightroom to enlarge a JPG output to a certain size while mainaining a specified PPI at export time or you can specify the PPI of your given print layout in the print module. If this doesn't give you satisfactory results, you may need software such as "Genuine Fractals 6" to enlarge your photo with less graininess.
Hope this helps.

Bought the adobe product to convert a pdf image to an RTF file but cannot figure out how to get it to work

HI wjleshe,
I've checked your account using the email address that you use here in the forums, but I don't see any order history. Did you perhaps sign up with a different email address? Or did you sign up via the Reader mobile app for iOS or Android? If you got your subscription via an in-app purchase, Adobe wouldn't have record of your order. And, you would need to contact the app store if there is a problem with your subscription.
Best,
Sara

Detecting PDF-image files in real time

Hi,
I'm planning to build a web application that allows users to upload PDF files. I want to be able to check the PDF files in real-time to ensure they only upload PDF text-searchable files, and not PDF image files. Is there anything from Adobe that has this functionality?
I'll probably to integrating it into a .NET web application.
Thanks.

Hi Leonard - thanks for the reply.
I've read up more about Adobe LiveCycle ES and it seems it might be a bit of an overkill for what I'm trying to do. I just need to have some software to check the PDF document whether it is text-searchable or not. LiveCycle appears to be a full document management and processing suite. Is there any more basic Adobe software that can do this kind of check?
Thanks much.

Size/Resolution of Backgrounds and Images

Hello,
I have seen tons of questions and answers about adjusting the resolution for images and I have seen many answers. But in my case I am designing my entire app in photoshop (buttons, backgrounds, images) and then I wanted to take those assets and put them
in my app.
But my question is what the appropriate resolution for my background images for one so they show up just as crisp and bright as the do in Photoshop? I know windows devices can support multiple resolutions but you shouldn't have images that are too large
to avoid slow loading, so with that being said what is the ideal size for background images to keep the crisp resolution?
And with images, I know I have to create multiple sizes to be able to quickly adjust to multiple resolution, can someone provide detailed guidance on how to go about that. The more specific with these 2 the better.
Thanks!
