PDF file size limited to graphics memory in Reader?

I've created a form (in LiveCycleDS) that allows for an unlimited number of photos to be loaded into it. I put an image into a subform that is duplicated every time a user clicks a button thus creating an unlimited number of images that can hold photos. I then extended it with Reader Extensions.
I'm running into a problem when I try to load a large number of photos into the form. It gets to about 47MB of images when it locks-up Adobe reader. I've been able to bring up other applications after the lock-up and when I switch back to Reader the artifacts of the other application are then displayed within Reader.
What is the practical limit to the size of a file created with LiveCycle? Is it tied to the amount of graphics memory a computer has? My machine has 2GB of RAM while my video card has only 384MB. I haven't been able to figure out if there is a file size limitation.

It's entirely normal for file size to increase. PDFs are much more compressed than print streams. For some printers the print size is almost constant (a huge bitmap), for others, it's a collection of graphical items and the size varies enormously. Rarely anything you can do.

.pdf file size limits

Is there a limit to .pdf file size or page count?

Just to confirm what Bill said —
I have several 'boxes' that I use each day.
They range from the typical, adequate, lower price point to a high end 'power-box'.
I have occasion to combine a large PDF document collection into a single PDF having a foot print of just under 800Mb (page count out around 2,000).
When using the 'typical, adequate, lower price point' box this large PDF can only be consumed at a crawl.
Bottom line is that the typical box has less RAM, resources, and integrated graphics rather than a adequately robust independent graphics card.
These boxes just do not provide the 'logistical' support to applications (Adobe Reader, Acrobat, whatever) that render PDFs with the very high file size foot print.
Particularly so if the PDF contains a good dose of graphics.
For the most part I've found that end-users seriously avoid such PDFs.
Be well...

Nio ByteBuffer and memory-mapped file size limitation

I have a question/issue regarding ByteBuffer and memory-mapped file size limitations. I recently started using NIO FileChannels and ByteBuffers to store and process buffers of binary data. Until now, the maximum individual ByteBuffer/memory-mapped file size I have needed to process was around 80MB.
However, I need to now begin processing larger buffers of binary data from a new source. Initial testing with buffer sizes above 100MB result in IOExceptions (java.lang.OutOfMemoryError: Map failed).
I am using 32bit Windows XP; 2GB of memory (typically 1.3 to 1.5GB free); Java version 1.6.0_03; with -Xmx set to 1280m. Decreasing the Java heap max size down 768m does result in the ability to memory map larger buffers to files, but never bigger than roughly 500MB. However, the application that uses this code contains other components that require the -xMx option to be set to 1280.
The following simple code segment executed by itself will produce the IOException for me when executed using -Xmx1280m. If I use -Xmx768m, I can increase the buffer size up to around 300MB, but never to a size that I would think I could map.
try
String mapFile = "C:/temp/" + UUID.randomUUID().toString() + ".tmp";
FileChannel rwChan = new RandomAccessFile( mapFile, "rw").getChannel();
ByteBuffer byteBuffer = rwChan.map( FileChannel.MapMode.READ_WRITE,
0, 100000000 );
rwChan.close();
catch( Exception e )
e.printStackTrace();
I am hoping that someone can shed some light on the factors that affect the amount of data that may be memory mapped to/in a file at one time. I have investigated this for some time now and based on my understanding of how memory mapped files are supposed to work, I would think that I could map ByteBuffers to files larger than 500MB. I believe that address space plays a role, but I admittedly am no OS address space expert.
Thanks in advance for any input.

Report file size limitation when printing?

Does anyone know of a file size limitation when printing a .NET run Crystal report? We run a browser app, which opens a new browser when a report is printed. That works fine. When we PRINT, the ActiveX print dialog box appears. If the report is large (> 40 pages or so) it crashes our entire application. It works ok if we export to PDF then print, but I am trying to get to the bottom of why it is crashing.

Hello,
What version of Cr and .NET?
Does your printer have limited memory?
Is it local printer?
Have you tried installing the latest Drivers for it?
What Browser are you using and have you tried any other?
40 pages not much local memory so it shouldn't be a problem.
Create a new Printer and select File rather than port or LPT as the destination to see if it's a physical printer or network issue.
Try a different printer altogether also.
Also refer to Rule of Engagement posting before submitting your question so you provide as much info first.
Thank you

PDF File Size - any way to compress further?

We have are using the Crystal for .NET export method to export a report to a .pdf file, and are having an issue with the pdf file size on a report that contains images. The images are stored in a SQL2005 database as blob or varbinary(max). The report executes a stored procedure that selects data (including images) to produce a quotation. There are input parms to decide which images to print (for example A, B or both A&B). Both types of images can appear at the line level on the quotation. Type A images print in the main report, Type B images are in a subreport. Both the main report & subreport execute a stored procedure to select an image type.
Our issue, when both Type A and B image is selected to print on a 293 line quote. The PDF file size is 44.23MB
When Type A only is selected, the PDF file size is 2.64MB
When Type B only is selected, the PFD file size is 43.95MB.
There are more Type B images that would print at the line level than Type A, but is there any way to compress this down further as it is too large to email.

You mention that you are using Crystal for .NET, but not what version; CR for .NET 2003, 2005, 2008. 2010?
Applying the latest fixes for the correct version of CR would be the first thing to do.
Next, I'd have a close look at image B as it appears to be the one adding the most "bulk". How is this image different from image A?
General tips re. images:
Save the files a BMPs.
When .jpg image is inserted into Crystal Reports it is converted into bitmap format and as the result of the conversion the report may loose some quality, scale and other issues may arise... E.g.; Crystal Reports is not so good a graphics management tool
When an image is saved as a .bmp, then there is no conversion required and thus the quality of the image should be preserved.
Best practice: save the image with high resolution and required size as a .bmp format then insert this image into Crystal Reports.
Resize the image to the smallest possible size and downgrade the DPI to 72. This will ensure your image is as small as possible and Crystal Reports will have to put in the least amount of work to display it.
Have a look ar KB [1241630 - Exporting a Crystal report (XI) to PDF generates a big PDF file|http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes_boj/sdn_oss_boj_bi/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes%7B6163636573733d36393736354636443646363436353344333933393338323636393736354637333631373036453646373436353733354636453735364436323635373233443330333033303331333233343331333633333330%7D.do]. This KB, may apply to your version of CR, or not. In any case, you will have to use the KB as a guide and determine what the appropriate registry entry would be for your version of CR.
One more thing. Many people like to use jpg files as they are smaller than bmp files. However, as far as Crystal Reports is concerned, this is inconsequential. The report file will be the same size if a file is inserted as a jpg or a bmp. This is due to the jpg conversion to bmp Crystal Reports does internally.

Is there a file size limitation to using this service?

I am working on a large PDF file (26 mb) and I need to re-size the original and mess with the margins. I don't beleive there is an easy way to do this in Adobe Acrobat 6.0 Pro. It sounds like I have to convert the file back to a Word document, do the adjustments there and then produce a new PDF. I have two questions:
Is there a file size limitation to using this service?
Will a PDF to Word doc. conversion mantain the format of the orginal PDF?
Thanks
Tim

Good day Tim,
There is a 100MB file size limitation for submitting files to the ExportPDF service. As for the quality of the conversion, from our FAQ entitled Will Adobe ExportPDF convert both text and formatting information?:
Adobe ExportPDF is capable of exporting high quality information, but the quality of your Word or Excel document depends on the quality of the PDF file you start with. For instance, if your PDF file was originally authored in Microsoft Word or Excel and converted to PDF using the PDFMaker functionality of Adobe Acrobat®, your PDF file contains a rich set of information that can be captured by Adobe ExportPDF. This includes relative positioning of tables, images, and even multi-column text, as well as page, paragraph, and font attributes.
If your PDF file was originally authored using simpler PDF generation methods, such as “print to PDF” or “scan to PDF” options, Adobe ExportPDF will convert any recognizable text and then use sophisticated conversion intelligence to preserve as much of the page layout as possible.
Please let us know if you have any other questions!
Kind regards,
David

Large PDF file sizes when exporting from InDesign

Hi,
I was wondering if anyone knew why some PDF file sizes are so large when exporting from ID.
I create black and white user manuals with ID CS3. We post these online, so I try to get the file size down as much as possible.
There is only one .psd image in each manual. The content does not have any photographs, just Illustrator .eps diagrams and line drawings. I am trying to figure out why some PDF file sizes are so large.
Also, why the file sizes are so different.
For example, I have one ID document that is 3MB.
Exporting it at the smallest file size, the PDF file comes out at 2MB.
Then I have another ID document that is 10MB.
Exporting to PDF is 2MB (the same size as the smaller ID document)... this one has many more .eps's in it and a lot more pages.
Then I have another one that the ID size is 8MB and the PDF is 6MBwhy is this one so much larger than the 10MB ID document?
Any ideas on why this is happening and/or how I can reduce the file size.
I've tried adjusting the export compression and other settings but that didn't work.
I also tried to reduce them after the fact in Acrobat to see what would happen, but it doesn't reduce it all that much.
Thanks for any help,
Cathy

> Though, the sizes of the .eps's are only about 100K to 200K in size and they are linked, not embedded.
But they're embedded in the PDF.
> It's just strange though because our marketing department as an 80 page full color catalog that, when exported it is only 5MB. Their ID document uses many very large .tif files. So, I am leaning toward it being an .eps/.ai issue??
Issue implies there's something wrong, but I think this is just the way
it's supposed to work.
Line drawings, while usually fairly compact, cannot be lossy compressed.
The marketing department, though, may compress their very large TIFF
files as much as they like (with a corresponding loss of quality). It's
entirely possible to compress bitmaps to a smaller size than the
drawings those bitmaps were made from. You could test this yourself.
Just open a few of your EPS drawings in Photoshop, save as TIFF, place
in ID, and try various downsampling schemes. If you downsample enough,
you'll get the size of the PDF below a PDF that uses the same graphics
as line drawing EPS files. But you may have to downsample them beyond
recognition...

Web.Show_Document - Is there a file size limitation?

It appears that Web.Show_Document has a problem displaying large .pdfs.
Example: A .pdf size of *2505 KB* would not display, however I compressed the .pdf to *1172 KB* and the report displayed using web.show_document successfully.
I am displaying the .pdf in an Oracle forms using web.show_document. The user presses a button (View Report) and it displays the report. Except, now it is not displaying reports close to 2000 KB in size.
The error says **"Exhausted Resultset"**
Is there a file size limitation with web.show_document?
Environment Background:
Forms [32 Bit] Version 9.0.4.1.0 (Production)
Oracle Toolkit Version 9.0.4.1.0 (Production)
PL/SQL Version 9.0.1.5.1 (Production)
Report Builder 9.0.4.1.0
ORACLE Server Release 9.0.1.5.1
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production

As already mentioned, WEB.SHOW_DOCUMENT has nothing to do with file size. This command simply sends a url to the system's default browser. There is no Oracle magic here.
To the problem, you said:...The error says **"Exhausted Resultset"**Where are you seeing this message?
Is Forms generating this message?
Is this a custom message?
Is this the complete message text?
Is there an error number?
This does not appear to be a Forms generated error message.
I would suggest your store a large file in the same location as where your reports are located. The file should be of the same format (i.e. pdf). Open a browser and manually enter the necessary url to retrieve the content. I suspect the same problem would reproduce IF you believe the problem only occurs when the form calls WEB.SHOW. If it does reproduce then you have at least simplified the problem to a client browser requesting a document from a server.

PDF file size too large

Hi,
I have a report (6i and 9Ids) which contains an image (stored as a blob in the database (8i)). The size of the image in the database (and as a file) is just 750k. The image is sized to fit on to the A4 report page. If I set the desformat of this report to PDF the resulting PDF output file is 10mb in size. I need to make this report available over the web so this is too large. Has anyone got any ideas as to reducing the output file size?
I have tried the pdfcomp report parameter with no joy.
Cheers
Andy

Hi Andy,
The image you are using might be a JPEG image. In 6i and 9i, while generating the PDF file, Oracle Reports always converts the image to GIF and embed it. This image type conversion increases the file size of the outputimage and hence PDF file size increases. This is fixed in Oracle Reports 10g.
In Oracle Reports 10g, you can select the outputimageformat based on your need, using either:
1. commandline: OUTPUTIMAGEFORMAT
(or)
2. environment variable: REPORTS_OUTPUTIMAGEFORMAT
If your image in the database is a JPEG image, set the outputimageformat to JPEG. Hence, there will not be any image type conversion and the PDF file will be very small.
Please refer to the Publishing Reports manual to know more about the usage of these commandline/environment variable.

Reduce PDF File Size - any ideas?

Hi all,
I have a C++/C# programs that generates PDF's in Adobe Reader using Infragistics. This is a recent change from using VS View as our old method of illustrating - we now use Infragistics. This has resulted in our PDF File sizes almost doubling due to us now using Bookmarks within the PDFs and also having to embed the fonts. There are some pictures used but these are already very small so they are not the issue. I was wondering does anyone have any ideas of how we could possibly reduce the size again or any possible work arounds.
Any help would be great.

Where do these EPS files come from Photoshop or Illustrator?
Illustrator
There may be nothing wrong with EPS files technically, they are considered archaic in a modern workflow. Best to save as a .ai with pdf compatible file - or to save them as PDF x4a with Illustrator Editing Capabilities enabled.
But I don't think there's any need to run out and convert all your files - perhaps keep it in mind going forward.
Photoshop
EPS is really not the best format. If it's pure raster then PSD or TIFF would be preferred format, if it's Raster + Vector Shapes, Vector Masks, Text Layers then PDF is preferred over EPS (with photoshop editing capabilities enabled).
File sizes react differently depending on the content on the choice of compression. Heavy Vector files from Illustrator can cause Huge file sizes in PDFs.
See this article (and more importantly the comments!)
http://indesignsecrets.com/creating-smaller-pdfs-from-a-vector-dense-book.php
If you can provide a bit more info on your workflow and what settings you are using to save it would be great.

Using Examine Document Remove increases pdf file size !

Hi,
I have Adobe Acrobat Pro v9.3.0
I've been editing a lot of scanned .pdfs - rotating and cropping pages.
All this has previously worked fine with v8 but now I find that Acrobat 9 is increasing the .pdf file size after using Examine Document and clicking Remove
For example:
original file: 16,861 Kbytes
file after cropping 74 pages (from A4 to A5): 16,879 Kbytes
file after running Examine Document > Remove cropped metadata : 79,914 Kbytes !!!
With Acrobat 8 this process would normally have halved the file size.
Am I now doing something wrong ??
Thanks in advance.

Hello - This problem is still here !
Acrobat 9 Pro version 9.4.2
I've got a .pdf created by an agency (so not a scanned image) which I want to make as small as possible for emailing to hundreds of people (I'll attach it if possible somehow ?)
I open it up when it's 331Kb
Click Document > Examine Document
Check the Metadata and Deleted/Cropped items
Click Remove
Click File > Save As and hey presto, the new file with all that stuff supposedly removed is 2,588 Kb
Surely I'm not the only one who's bothered about .pdf file size ?

PDF file size

I have an HP Officejet 6500 E710n-z (Network) that I use at home to scan into PDFs, and I know exactly how to move the slider from "Smallest size" to "Best quality"
However the size of the PDFs are unacceptably large when image quality is acceptable, and if I move the slider to reduce the size then the image becomes unacceptable. It is impossible to scan a legal document of more than a few legible pages without producing a file size too large to email . I am forced to break these scanned documents into 3-4 page bite-sized chunks.
A simple one page HOA Disclosure form, at 220 DPI and the slider in the middle for balance, produces a 699K PDF. I have used other printer scanners at work (different brands) at the same 200 DPI that results in very clear documents at less than 100K per page.
I believe there is something wrong with HP's scan-to-PDF algorithm. The problem must be due to some unskilled (or flawed) software design. What will it take to have HP or third party developer (and developer staff supervision) take this seriously -- compare HP vs other brand scanners PDF files -- and update the HP drivers to fix this?
This question was solved.
View Solution.

Just a follow up. I went into chat mode with some low-level tech named Nathan, giving him the link to this thread. After reading it, he suggested I can improve file size by using greyscale and 200 DPI. DUH!!!! I complained he was just humoring me, so he said I should call the tech support number.
I did that next and spoke with a very nice young lady who actually DID take me seriously. I could hear her typing away vigorously in the background, capturing every detail of my plea for this to be forwarded up the chain of command for serious consideration. It was clear she understood and captured from me that there are many forum complaints that can be found with a search term "PDF File Size" that are getting weak or unacceptable "solutions" to push the slider left or use lower DPI etc. She also captured my assurances that some competitor brands produce PDF file sizes 20 times smaller for the same image quality.
I believe that this might actually be opened up at a higher level for consideration of an improvement in the compression algorithm. My fingers are crossed. Since I have about 11 months left for warranty support, I plan to contact them once or twice again before it expires, using the same case number to see if there is any progress.
Bottom line: At my default of 200 DPI and 20% image quality, with an average file size for a single sample page producing a file size of 281KB, a 25-page document creates a PDF file that is 7MB! That will just barely make it past the file size limit for my email provider, but might be too large for the recipient. That is still unacceptable, and is forcing me to consider products other than HP for this business purpose.

PDF File Size Problem

Hi,
I am using Adobe Acrobat Elements 7.0 in my computer to convert files like .txt and .doc to .pdf files. But currently I'm facing a problem with the converted .pdf file size. For example, my .doc file is 5MB and after I convert to a .pdf file, it becomes 10MB. The file size basically multiplies itself by 2.
I've tried converting .txt and .doc files and it gives me the same problem. I've tried reinstalling, tried all kinds of settings, and recreating user profile but it doesn't help. Can anyone help me? Thank you very much.

Sorry. The problem is caused when I want to password protect a .pdf using elements. So I used Adobe Reader to open the .pdf file then I'll print using Adobe Printer so that I can password protect it and output file size is actually 10 times the normal .pdf file.
Please help!!

Preview increases pdf file size when saving

When I save a PDF journal article using Preview, it often increases the file size by 2x - 4x, regardless of whether I have added annotations. In the attached image, you can see I downloaded a journal article (2.3 MB), opened it in Preview, duplicated and saved it and the resulting copied file was 6.1 MB.
This is a problem because I it signifiantly increases the size of my synced reference library. It is worse with larger files (25 MB eBooks that increase to 80 MB).
Can anyone help me find a way to annotate a journal article and preserve the original file size? I have tried Adobe Reader (awful and buggy interface, but preserves the original size!), and several other PDF apps (e.g. Skim) seem to rely on Apple's PDF engine where the file results in a larger size as well. Using Quartz filters to reduce file size within Preview is not effective. I'm happy to purchase a program if it works well.

I have also experienced this issue. My PDF file of 300MB increased to over 900MB when I simply put one straight line annotation onto it. Effectively this made the PDF unusable since it is now very slow to open and it is too large to transfer onto my iPad. I've experienced this multiple times with a variety of PDF files, and so now simply avoid changing them in any way in Preview. I have written to Apple via apple.com/feedback and have talked to Apple store 'Geniuses' about this. Apparently it is a known issue, but there was no promise of a resolution. I love the way Preview opens quickly and displays files and also allows beautiful, smooth scrolling of PDFs. It's a pity that there's this enormous problem with annotating. If anyone knows of a solution, it would be great to hear. I've tried other PDF programmes such as Adobe for Mac, but wasn't too impressed.

Question about reducing PDF file size on export

I have a large file that is generates a PDF about 75MB when exported with the "[High Quality Print]" preset. However, I can reduce the size down to to under 5MG in Acrobat if I use the Tools>Flattener Preview>[Medium Resolution] setting (image attached). Is there a way to generate this smaller file directly from InDesign? I couldn't figure out how to do this with InDesign's Flattener Preview or Export options, but it is very likely that I missed something.

Eugene Tyson wrote:
When you choose Smallest File size, it is still using the PDF 1.6 setting.
Change this to Acrobat 4 (PDF 1.3) this will automagically flatten the PDF - which means you shouldn't have to do it in Acrobat.
That should get you a nice small file size, I believe.
Flattening transparency in InDesign will not necessarily yield a smaller PDF file size. Transparency flattening will not automatically convert placed vector artwork to raster images unless that vector artwork is actually involved with transparency. And even then, whether you end up with a smaller file depends on a number of factors.
If the reason for the very large file size is indeed very complex vector artwork and you are willing to sacrifice quality, conversion of such vector artwork to raster might yield a significantly smaller exported PDF file. To accomplish that conversion, I would personally suggest converting the most offensive (in terms of file size and complexity) of such files in Illustrator (assuming that they were .AI files) and exporting them as .TIF files (to avoid the potential imaging artifacts of JPEG compression).
