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.
Regards,
Vinoth

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]

Illustrator CC opens file showing missing embedded images. Illustrator 5.1 opens same file fine with no missing images.

How do I get CC to open these files correctly? Is the client saving them incorrectly?
My work around has now become a pain & I need to know why Illustrator CC tells me most/all embedded images are missing in files received by clients.
Illustrator 5.1 opens the files ok & gives me no errors. It does a few funky things because ti says the file was produced with a new version. The file previews fine in the Finder window & shows all images. The issue with opening them in 5.1 is it wants to open 1 page at a time like the AI file is a PDF.
Why is CC failing to recognize the embedded images? Are the images not embedded correctly by the client? Is 5.1 pulling from some lower res version of the images? Files export from 5.1 as hires. Stumped.
Oh my gosh why arent they just using InDesign. : (

Please get informed about how Illustrator saves files and what exactly is in a file and how it is re-opened.
See: http://rwillustrator.blogspot.de/2006/11/whats-in-file.html
When in Illustrator CS5, Illustrator actually opens the PDF part of the file that contains all the images. Always.
When in Illustrator CC, Illustrator accesses the AI part of the file, which doesn't necessarily contain the images.

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.

How do I relink multiple instances of the same image, in Illustrator CC?

Is there a feature, like InDesign, where links automatically relink if they're in the same folder?
Currently I have to search through the file structure multiple times even if the linked image is the same.
Surely Illustrator should relink all instances of the same image and give the option search for any additional missing links in the same folder?
I'd love to be pointed in the right direction, or if anyone has a script they've written to solve the problem, do let me know.
Cheers

try the script (version 3) in this post,

Issue opening .AI file with linked/embedded images in Illustrator 6

Received an Illustrator 16.x ai file with 6 Linked\embedded images. Opening in Illustrator 16.0.3 2 images are missing, but opening in Illustrator 15.1 opens them correctly. Illustrator 16.0.3 has warning "Could not find linked file “filename.png”. Choose replace to select another file or Ignore to leave the link unchanged". Illustrator 15.1 has warning "The file “filename.ai” was created by a newer version of Illustrator. Would you like to import this file? Some data loss may occur.". When I open in Photoshop 12.1 and select Images only 4 images show. The two that are missing in ai. are not showing in Photoshop Images option tab, but are in Photoshop when I open the file using pages option tab. Any idea what is happening here and why Illustrator 15.1 opens fine, but Illustrator 16.0.3 cannot?
Thanks, Dale

Illustrator CS5 opens the PDF part of the file. Images are always embedded in that part, but you might not be able to edit all objects in it.
Illustrator CS6 will access the AI part of the file, where linked images are not embedded. You should ask for the images in order to edit the file.

Missing filenames when embedding images in Illustrator

Hey,
I was wondering if anyone would know how to find the original filenames in Illustrator after the image had been embedded? My company has several old files where all the images are embedded and it's proving to be quite the nightmare in trying to relocate those images. Is there a way that you can view the filename after it has been embedded and the filename disappears? If anyone knows, I would greatly appreciate that help.

sorry...there is no way to do it

How to check in IDCS4 the rgb images?

Apparently the Preflight panel does not consider this option and the links option (which shows this condition) is a calamity because you have to touch photo by photo and the vertical arrows to speed the process do not work at all...

Of course it's in the Preflight options!
[PS. What Ho? Why doesn't the image upload work anymore? It sez [The content type of this image is not allowed.] ... for a PNG?]

Embedding Images in Illustrator CS5

Just upgraded to Yosemite form Snow Leopard and use Illustrator CS5.1. I had it auto embedding my images but it would still show my path/file name in the links pallet...now once the image is embedded it just gets rid of my link. How can I fix this?

There could be two resons for this:
The size of the image you are placing is larger than the canvas size i.e approx 16300 * 16300 pt
Another could be the memory related, i.e the Ai is hitting the limits..
Try placing the file after reducing the dimensions..

Why can't I print embedded images in a Thunderbird E-mail? I just get blank boxes for the images.

I am a copyeditor who receives feedback from my clients re: manuscripts I have edited. They will often sent e-mails that include small screen captures from parts of their style guide or screen captures of the proof that is in question (small sections, like a paragraph or an equation, or a header that needs to be coded/styled differently for HTML). Now, I can see these fine in the e-mail, but when I go to print them out for my reference binder, the embedded images don't print.
Mozilla, I need these to print; they are quite important to my job.
To keep my e-mail from becoming too bloated, I save these important style issue e-mails into a folder on my desktop I call "Print out for binder", queuing them for the day I can print a bunch of them out and arrange them according to subject matter.
Problem is, they are useless if they don't include these illustrative screen captures; blank boxes are worthless to the context.
It is not my printer that is the problem. if I receive a Word doc with these screen captures, they print fine. But if I try to print from T-Bird, no go. Help. (I can't save these e-mails as Word docs either, which might solve the problem; the only options in T-Bird are "Save as file" or "Save as template".)
Thunderbird is a powerful e-mail program, and one I have been using for over a decade. Why can't it perform this function? Please help. Or point me to an add-on. I haven't been able to find one that addresses this seemingly straightforward, common, and simple problem.

When you select File(or AppMenu/Print)/Print Preview, do the images appear? Do the images print if you check 'Print background (colors & images)' under File/Page Setup? I don't have any problems printing a message with an embedded image, at least to an xps file.
I devised a workaround that might help, failing a real solution: install [https://addons.mozilla.org/en-US/thunderbird/addon/unmht/ unMHT] in both TB and Firefox, and then File/Save As MHT in TB. Open the mht file in Firefox, and Print.

Getting desired resolution of the images created by Powerpoint conversion service using PictureRequest class

I am using PictureRequest class to get the images of the presentation as,
PictureRequest request = new PictureRequest(inStream, ".pptx", PictureFormat.Png, outStream);
IAsyncResult result = request.BeginConvert(SPServiceContext.GetContext(siteCollection), null, null);
request.EndConvert(result);
After getting the response from the PictureRequest if I check the image size (in this case png) it has the resolution of 720x540. I want bigger resolution images. I searched all over the sharepoint central administration but could not find any setting related
to Powerpoint conversion service which may allow to set the desired image resolution.
Could you please anyone suggest where I can specify the required resolution?
Many thanks in advance!

Hi,
According to your description, you want to convert PPT file to PNG file in a specific resolution.
There is no such OOTB settings in PowerPoint conversion service can meet your requirement. In
PictureRequest object, there is also no related method can set the resolution of the converting image.
As a workaround, I would suggest you do the conversion outside SharePoint, there will be more options available to handle the properties of the converted images.

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).

Extract Embedded Images-did you know that-

there is actually a feature in Illustrator to do this even though it is not called Extract Images?
Not only that once you extract the image you can update it as well you do not have to lace it again and reposition it.
When I saw this and realize it was there I could not believe it as it has been asked so many times and there have been numerous work arounds.
The reason I think it has passed everyone by is that it is not located in the links panel.
So to the chase.
Edit>Edit Image
and then
Edit>Update Image
The former opens the embedded image in Photoshop
edit it there and then save it
then back in Illustrator go to the latter and it will be updated.
Never noticed this before.
The only draw back is that it seems to only work on one image at a time.
I wonder how many users here knew about this little feature?

Why not?
You will have trouble getting the original resolution in case the image has been scaled in Illustrator.
Yes you're right about that, and it is the best way if you have the original Illustrator file with the embedded image.
In my defense, I'm mostly having to do this sort of thing with PDFs that are sent to me. Most cases I have to change something in the PDF or pull artwork out for another project we are working on. After opening the PDF in Illustrator, we then just copy the image and even paste it straight into an email (Mac) and request the original file. If the original is not to be had, we then paste the image into a new Photoshop file and relink it. If need be, we'll replace it with another image later.
@rijackson --- you most surely can "Relink"... well that's what the button you choose in Illustrator is called... even if the image is embedded. This will place the image in the exact same place and size as the embedded image, thus "linking" it if you checked the Link box when placing.
Also, you can always choose Link Information and see what transformations the image has went through regarding size and rotation. This is also with a native Illustrator file only. The information can be used to calculate what you need to do to the image to revert to it's original size and rotation. Rather unfortunate, because something intuitive like Freehand used to have, like changing the percentage and angle in the Appearance panel was far better and easier to revert images, embedded or linked.
@rijackson --- considering all of the features and functions that Illustrator still does not have or are incomplete... yes, Illustrator as a whole is pathetic as the only pro vector alternative on the market. Not just this one omission, which is easily worked around. That's what I was trying to say to wazi9909.
* I just thought it should be mentioned again, that Monika's correct answer only applies to a native Illustrator file if you have it, AND if you save with PDF Compatibility or as an Illustrator native PDF. With any and all other PDFs saved with a preset like for prepress... the images have been compressed, and will be as we call them "baked". No matter how you copy, paste, export or open, the resolution, size and quality is "finished".
