Rasterize PDF graphics

I've built a presentation where almost every slide has one or more PDF graphics (actually Illustrator files). They load okay on the mac (slight lag when displaying the slides with lots of them), but I'm getting horrible lag on the iPhone version. I suspect its rasterizing each vector before rendering it, and that's taking forever on the A5 chip. Is there a way for Keynote to pre-rasterize all the graphics at their current sizes (meaning I don't have to export each image through Illustrator and put them back in, trying to make things the same size) so it'll load faster across both platforms? Is there a Rasterize command in Keynote that I'm missing?

Thanks Barbara, you got me on the right direction. Not exactly sure the difference between the different kinds of JPEG files. However, it seemed to me that the graphics were simply not liked by iOS. I found a post on a different forum that said if you open the PDF file up on a PC using current Adobe Acrobat, or on a Mac using Preview with current Mac OS, you should use the program to save a copy of the PDF file, which somehow comes out different than the original. I am figuring that the new file gets reassembled with current formats. I did this on Preview on my Mac. The new file was x4 the size. I took the new file, dragged it into iTunes, synched it over to my iPad and it worked! The pictures were there with just a little graphics degradation, but not enough to seriously matter. When I used Adobe on a PC, I could see that there were security features enabled on file. When I made a copy, all I got was a blank file. So, hats off to the Mac here.

Lower PDf graphics quality after upgrade from v8 to v9

Some PDF Graphic quality is poorer whne using the new Acrobat compared to version 8.
I recently purchased Acrobat 9 Pro extended as part of the TCS2 and installe dhtis on a new machine. The installation replaces Acrobat 8 professional installed on a different machine.
I have checked the job options in detail on each machine and they appear to be identical.
The problem is most notable in a graphic header which appears on the first page of the Word document template from which the PDF is generated. The file is an imported PNG with a complex blue gradient band and the company logo across the top of the page. The band is underlined by a thinner grey band which fades vertically to white. In the resulting output, blue colors show too bright and quite different to the original PNG graphic. The grey band does not fade smoothly and appears as separate bands.
My colleague has installed Acrobat 9 on the same machine as the previous Acrobat 8 installation and is experiencing the same issue.
I have tried generating a PDf with an old known good file base don the same word template and the result is the same so this probably rules out the Word template. Older PDFs generated with the v8 Acrobat do not do not display this way and i still can generate PDFs using the old machine and version 8 Acrobat without any problems.
Can anyone suggest how i might progress with this?

There are no display problems because i can satisfactorily generate the file using the Print option and selecting the AdobePDf printer.
I have set the Color Management Policies of the joboption to Convert all Colors to CMYK from Leave Color Unchnaged and this seems to improve the quality considerably so i'll stick with that. Some gray color gradient doesnt seem to convert smoothly and shows as varying bands of shades of gray but i can live with that, unless i can find a setitng that handles that.

Placing a PDF graphic into an existing XML hierarchy?

I have an existing XML hierarchy that has a picture element that looks like this:
<picture href=""></picture>
which is already placed in a TextFrame.
I'd like to place a PDF graphic at the location of this element, in essence updating it.
I'm able to update the href attribute with the correct filename, but this doesn't create a placed graphic AFAICT.
I can place a graphic in my TextFrame, but don't understand how to specify this <picture> element as its location.
Any pointers to example code, or hints/tips?
Greatly appreciated!
Charles

Oh, right. Did we forget to tell you that trying to use XML in InDesign is usually a bad idea and that you could do much better without it?
Anywhohowwhichwhywhere...
In keeping with that theme, XML doesn't really come into play. If you have a rectangular frame rect and a filename filename and you want to place filename in the rect then you just use: rect.place(filename);
So in your case, it's just about defining the two. I guess:
var rect, filename;
rect = app.documents[0].selection[ROW].associatedXMLElement.
xmlElements[COL].xmlElements[0].xmlElements[0];
filename = new File(rect.xmlAttributes[0].value);
rect.place(filename);
Of course, if your filename is really a URL you'll have a spot of trouble there, maybe.
And you might be better off using XPath, i.e. .evaluteXPathExpression("//picture") to get your rectangle.
And what if href= isn't the first attribute of the <picture/> tag?
I suppose that perhaps you should consider using the .placeIntoFrame() and .placeXML() methods of the XMLElement class. I suspect you'll be sorry if you try, but go ahead :-).

Export PDF Graphic

I need to Extract a PDF graphic, crop and save as a new PDF. Not sure how to do this. Can anyone help me out with this?

There is a crop tool you can use. You can also use the select object tool and right click on the graphic and see if you can edit it in your preselected program (you can choose a default raster imaging editor and a vector graphic editor in Preferences -> Content Editing)

Getting thumbs to show up from PDF graphics

I'm having trouble getting some of the thumbnails to show up in my Artwork palette - specifically, the graphics that are in PDF format. I've regenerated the palette by holding <Shift> on relaunch, removed & re-added the pdfs themselves, created new pdf graphics to test if THEY show up (they don't), even deleted the .db3 files for both media & thumbnails (folks, I don't recommend doing that unless you ABSOLUTELY have to) - but still no thumbs from PDF graphics. Anyone got another idea? Mike http://www.graficalicus.com

Ian. I think the OP is states they purchased songs from WiFi iTunes off the iPhone. Went into iTunes to convert to ringtone but they are not showing up correctly.
OP if you could post better details about what you are experiencing and doing we can better assist. I think I have a good sense of what is going on but would need more info before anyone here can properly advise.

Robohelp fails on PDF graphics conversion

Robohelp obviously fail at converting FrameMaker files the contain imported PDF graphics.
If a FrameMaker file contains graphics as referenced PDFs in anchored frames, this graphics will get converted to completely white JPGs (or PNGs).
This is not really what one expects from a tool like that.

Hi Jess - ES is jut running on a virgin XP SP2 Virtual PC (2gb RAM dedicated) so no other processes should be accessing it.
One thing I wondered - for the ES Preview, you get a 30 day eval of Acrobat 8.1 Pro - which of course usually comes up with the 'this is an eval - do you want to buy/continue' I would not have thought it would have been included if a problem, but could that be it?
"Check to be sure the environment variables are set up correctly - this should be done automatically during installation and deployment."
- all the JDK stuff was checked and seemed fine.
Major problem is the vagueness of the LC error msg - any way to get more detailed error info??
Thanks

Problems converting word in PDF, graphics

I use Acrobat X Pro and Word 2003 SP3.
Photos change their size in the PDF.
If the photo-size was never changed in Word, the photos stay as they were, but if the size of an inserted photo was slightly changed in word, this photo is in the PDF in its "original size" (the size it had when it was imported). Of course I try not to change photo- or graphic-size in word, but I took over a big amount of word-docs with inserted graphics and photos and I do not have all the inserted photos to change their size an reimport them.
So maybe someone knows, how to change this habit. Or has a hint which settings in AcrobatX I could change. Or a hint whether I should leave Acrobat and better change settings in Word. Acrobat9 didn't do that sort of thing. So it's probably rather an AcrobatX-problem.
Either way I can't give this layout to my boss.
Thx for help

Never had that problem. I suspect it is a word problem and you should be able to find out by printing from WORD to paper. If you want to play with a copy of the WORD file, right click on one of the graphics and select the Compress option. This will reduce the picture pixels to better fit the document. Then try a print. If this fixes the problem, then you have a potential fix and know it is a WORD issue most likely. You might consider updating WORD as well as Acrobat.

FM makes nice PDF graphic look bad. Why?

We are having a tough time with graphics that were created in Interleaf. I make a PDF of the Interleaf document and it looks/prints excellent, just like the original in Interleaf. But, when I import it into FM and print, it looks quite bad. If I open the same PDF in Illustrator and save it as a PDF from there, then import into FM, it prints fine. Same thing if I save the same PDF as an AI file and import to FM. It prints fine. Do I really need to resave all my PDFs in AI or is there a better way? It seems like FM should be able to handle the original PDF as well as AI, but it doesn't. Maybe I am missing something...
Any thoughts? Thx!!

Link is below. Thank you. Upon further review I see that the schematic is being coverted into a million pieces when it is exported from Interleaf. I think that is the problem. Let me know what you think...

Illustrator pdf graphic problems

Hi All,
I have a file which I need to send to a printer as locked pdf, but am having problems with my graphics saving correctly.
The magazine I am publishing in cannot be trusted to not tinker with the artwork (messed up last 2 years advertisements mucking around with layout), hence trying to make this as secure as possible.
I have created some cartoon like clouds and when I save the artwork as pdf they have pencil thin grid lines all over them, as if they have been broken up into large square shapes in the save process.
Strangely, if I flatten the artwork in Illustrator I get the same result.
Any ideas?
Many thanks, Jon

Do the clouds involve transparency and/or raster effects? If so, you are probably seeing the onscreen antialiasing where the resulting raster images abut after you Flatten.
Turn off antialised display in Prefs and see if the "gridlines" go away.

Adobe pdf graphics in Word

i am trying to create a snapshot of a graphic and paste it into word 2010. however it is either blured of too feint. please can someone help me setup adobe so i can do this

There is not a simple clip from a PDF file (other than the snapshot tool that clips at the screen resolution -- probably your problem).
A relatively easy way to get what you need, but with a few steps, is to open a new blank document from the file menu in Acrobat. Then go to the original file and use the object touchup tool (maybe the select tool also will do it) and copy the graphic to the blank PDF. Then use Advanced>Document processing to Export All Images. That should pretty much be the original image (I save as a TIFF usually) that can then be imported as an image to WORD.
If you have a graphic in file that had been created from WORD 2007 and later, then you may have an issue that the image has been broken into multiple parts. That appears to be a gotya from MS.

Why does Firefox 37.0.1 show multiple overlapped tab icons + same some pdf graphics? (36.0.4 is OK)

When running on SONY VAIO i7 WIN 7 64bit SP1 with NVIDIA GeForce GT 520M, the icons in the tabs at top of Firefox page replicate, overlapped, horizontally, offset by a few pixels in 37.0.1. Similarly, when displaying web based pdf files through Firefox 37.0.1, some graphics replicate, overlapping, vertically. There are no such problems in 36.0.4 or previous. My drivers for GeForce GT 520M are up to date, so not a driver issue. I have uninstalled 37.0.1 and reinstalled 36.0.4 until this can be fixed.

48"x48" poster PDF - graphics distorted

Good evening,
I'm having some minor difficulties tonight. Nothing that I can't handle via a workaround, but was wondering if anyone knew why some InDesign elements are getting distorted in my PDFs.
Here's the process I'm going through:
I'm working on a 48"x48" poster that includes a logo, some text and some multi-angled shapes that I drew with the pen tool in InDesign on a blank background. The shapes extend from the very top edge down to the very bottom edge.
When I look at the PDF that I generate, however, the shapes that I drew in InDesign have been squashed to about 2/3 their true height (it's not just missing the bottom third -- the shapes are actually distorted, the bottom of the shapes being pulled up and the angles adjusted accordingly).
And, to go over my PostScript file generation process:
I have a Print Preset in InDesign that I use to create a PostScript file, which I then drag to Distiller, which is set to the PDF/X-1A:2001 setting.
My Print Preset for generating the PostScript file includes the following settings:
Printer: PostScript File
PPD: AdobePDF 8.0
Paper Size: Custom (which automatically sets the size of the PDF to my document size)
Marks/Bleeds: (all off)
Is there something I'm missing? Is it just due to the 48" size of the InDesign document (I've saved a separate, half-size version of the InDesign file and created a PDF of that one and it looks fine)?
I've tried exporting the page as an EPS, resaving from Illustrator, dragging that EPS to Distiller to create a new PDF (same issue) as well as placing that EPS back into InDesign and re-creating the PDF (same issue).
The only thing that makes the PDF look correct is setting the InDesign file to a percent scale of the actual size ... or doing a standard Export and selecting Adobe PDF from the drop-down list (which can create unreliable files that may look fine on-screen but then print incorrectly, so I typically don't use this method).
One other note: on a separate test file I created, I added a black fill to the background of a 48"x48" InDesign file, drew a similar multi-angled shape on top of it in another color, used my normal PostScript file-to-Distiller method of creating a PDF, and the black actually filled the canvas in the PDF, but this new multi-angle shape was, again, distorted.
Any thoughts on why this might be happening?
Thanks!
Oops, forgot my versions:
InDesign CS2
Acrobat Professional 8.1.2
Mac OS X 10.4.11

There does not seems to be any preference that can be set. Clipboard text or images are placed as stamps.
One option for people who just need to paste text would be for them to insert a text comment field and paste their formatted text from Word there. (The reason to paste from Word is because the formatting will be maintained.)
Your customers may want to consider making their own custom stamp for their logo and/or any standard text that they want to appear on your newsletter. If they had their logo and text set up in Word, they could create a pdf using Acrobat.com or another free service. In Reader, they could use that pdf to define a custom stamp. A custom stamp would eliminate cutting and pasting and could be resized easily. The stamps could only be used in pdf documents that have commenting enabled, but they would not have to create a custom stamp for each newsletter – previously made stamps would be available to use in future newsletters.

Best Adobe product for editing PDF, replacing English text with Thai without altering/recompressing images, graphics etc.?

I have an English language PDF, a medical device brochure, the content of which has already been translated into Thai (in Word). I want to replace the original English in the PDF with the Thai translation easily without altering any other aspect of the brochure, like graphics, images, margins etc. (No doubt I'll have to tweak line height, font sizes and paragraph lengths a little.) I'm unsure of what would be the best Adobe product for this purpose, e.g. Illustrator, InDesign or Acrobat (or something else), that would allow me simply to open the PDF, replace the English with Thai in an attractive Thai font (to be embedded), make minor layout tweaks, then save without any compression so the quality and colours of the original photos, artwork, and graphical elements are preserved. I've heard Office 2013 allows direct editing of a PDF but I'm not sure if it converts, alters or compresses PDF graphics in some way when first opening the file. Could anyone with relevant experience please advise? Thanks in advance.

Adobe's only offering here is Adobe Acrobat. However, I must say something. I have heard from many people who sought to translate a PDF in this way. NONE SUCCEEDED. PDF is not suitable for this purpose. Obtain the original, this should be part of your contract for translation. If this is impossible, expect to remake the document; Word is probably unsuitable for a brochure of this type, maybe InDesign.

Bug: QT Pro fails to properly play PDF image sequence?

Hi folks,
I have a series of numbered PDF files that represent an animation. I can open these files as an "image sequence" with QuickTime Pro, but then the resulting movie seems corrupt. Only the first frame renders properly, and the remaining frames are white, sometimes with some garbled information from the PDF. (I'm using the latest version of QT Pro.)
Is this a known limitation? Should QT be able to open a sequence of PDFs properly?
I know that as a workaround I can rasterize the PDFs first, but this isn't really what I need. The eventual goal is to get this animation into Motion, so keeping the vector graphics as vectors for as long as possible is important. Also note that directly importing the image sequence into Motion produces the same problem, so I suspect that this is a QuickTime issue.
Any thoughts?

I believe QuickTime will only show page 1 of a single PDF, I'm not sure if that applies to multiple single-page PDF's within a single mov file though.
http://developer.apple.com/qa/qa2001/qa1247.html
So they are saying that if imported as a movie it can display multiple pages, if brought in as a graphic it can't.
Instead of importing as an image sequence, you could open each pdf in QT Player, select all, copy, paste into the final movie (or seperate movies which you could then import) and hopefully you would end up with movies of multi-page pdfs instead of single page pdf graphics. What a mess.

PDF dropped into Motion problem

I created some graphic text in Illustrator, using the Extrude/Bevel effect, and saved it as an .ai file. Then I dropped the graphic into Motion. In Motion the image remains sharp even when large on the screen. The problem (and I wish I could attach a file to show it instead of describing it, but here it goes) is that in the curved areas of the text, in the smooth gradient blend in the extruded part of the text, there are horizontal lines going from the face to the back of the text. These lines appear to be banding from the blending steps, but they look smooth in Illustrator.
Any ideas? Has anyone successfully brought text extruded in Illustrator into Motion? Motion's Extrude Filter seems a little fuzzy, so I'd prefer not to use it. Seems to rasterize the graphic when it applies the filter.

Thank you. I had fixed resolution off. The image looked very sharp, even when enlarged. But, the lines (which are sharp) are in the curved parts of the gradiant. I Changed the bit resolution to 32-bit (it was 8-bit), but that didn't make a difference.
I tried this experiment: Instead of bringing the .ai into Motion and letting Motion convert it to a PDF, I rasterized the graphic in Illustrator first, then saved it as a PDF with 1200 dpi. This worked getting rid of the lines and the image looked very sharp when enlarged in Motion. BUT, the file size is 97 MB (compared to 1 MB) and the graphic gets unsmooth when it is smaller on the screen. So, this is not really a solution.
I'm guessing the problem has something to do with Motion's .ai to PDF conversion? The original in Illustrator has very mild, exceptable banding (to my eye), but when brought into Motion the bands become this sharp, thin, black lines.
