Hello First of all, I want to apologize for all sorts of errors made while submitting this request for help, since this is my first time submitting to a mailing list. First the core problem maybe someone did experience the similar problems:
I am generating PDF Files containing JPEG images using FOP. Those PDF-Files previously readable with Acrobat Reader 6 are causing an Error since Acrobat Reader 7. Since we dont have influence on the Acrobat Reader Versions our customers use and Adobe has not fixed the Problem in the new Acrobat Reader 8.1 I am pretty desperate to find a solution or workaround for this Problem. The Error displayed by Acrobat Reader is something like: Not enough data for an image (Nicht genügend Daten für ein Bild) After the error has surfaced the Reader stopps to render the Document correctly. At first only certain images are not displayed while moving around the document afterwards the rendered content disappears. Those certain JPEG images derived from our database do not have DPI information stored in them. Since supplying those malfunctioning images with DPI information and generating the PDF anew made the Document readable I strongly believe that this is the cause for my problem. Sadly fixing the images is not an option for me, since the amount of images is huge and the risk of migration is too great for my company. I have found out that when using JPEG images and removing DPI information manually, the generated PDF will not necessarily cause the error in Acrobat Reader. (maybe there is some other factor involved) While searching for a workaround I have tried the following: *I have tested this issue with FOP Versions 0.93, 0.92 and 0.20.5 resulting in the same error as in the Struts (cx) integrated solution we use for our customers. *I have tried to reduce the xsl:fo code to a bare minimum and reducing the amount of images in the document which did not help either. Normally there are up to 10 images on each page with 2 pages per document. Here is the corresponding code: <?xml version="1.0" encoding="ISO-8859-1" ?> <fo:root xmlns:fox="http://xml.apache.org/fop/extensions"; xmlns:xi="http://www.w3.org/2001/Xinclude"; xmlns:fo="http://www.w3.org/1999/XSL/Format";> <fo:layout-master-set> <fo:page-sequence-master master-name="pagemaster1"> <fo:repeatable-page-master-reference master-name="first" maximum-repeats="no-limit" master-reference="first" /> </fo:page-sequence-master> <fo:simple-page-master margin-right="1.0cm" margin-left="1.0cm" margin-bottom="0.5cm" margin-top="0.5cm" page-width="29.7cm" page-height="21cm" master-name="first"> <fo:region-body margin-top="1.0cm" margin-bottom="1.0cm" /> <fo:region-before extent="1.0cm" /> <fo:region-after extent="1.0cm" /> </fo:simple-page-master> </fo:layout-master-set> <fo:page-sequence master-reference="first" initial-page-number="1" force-page-count="no-force"> <fo:flow flow-name="xsl-region-body"> <fo:block> <fo:external-graphic scaling="uniform" content-width="3.75cm" content-height="5cm" width="3.75cm" height="5cm" src="url('images/testimage.jpg')" /> </fo:block> </fo:flow> </fo:page-sequence> </fo:root> *I have tried to make contact with Adobe about this matter, but at the moment it seems I am on my own thats why Im looking for help here *Ive searched the Acrobat Reader options for settings that could work around this problem, but I have only found a way to stop display large images. This replaces images on the document with a gray rectangle. The error is not displayed using this setting, but our customers say that this is not acceptable for them. Any help would be welcome to find a workaround for this problem. I would favour a way to handle this in xsl:fo, but I still have not found a solution in the documentation available. If this is an issue of the PDF-rendering module of FOP it would be good to know, but it would limit our options considerably. (maybe force us to use different libraries) Yours Stefan Fassel (Germany) _______________________________________________________________________ Jetzt neu!
