Re: PDF size reduction

[TvT]

Another possibility is to post process your PDF. We for instance first
generate the PDF and afterwards use some other PDF library to shrink the
images and remove unused objects and other stuff...
If something is possible with a PDF in question you may try out with
acrobat - there are options to optimize and shrink your PDF. If there is no
reduction in file size with those options you may already have the perfect
PDF without any overhead ;-)

Re: Is it possible to merger pdf's using xsl-fo alone?

[TvT]

If you have two PDF documents then it is not possible to merge those with
XSL-FO / Apache FOP.
You have to use iText or PdfBox for this...

If you have two XSL-FO files you may be able to merge those with normal xml
operations and afterwards create one pdf out of it...

 Hi,

 Now we are using Itext for merging pdf's.
 Is there any solution to merge pdf's without using itext..

 Note: Is it possible to merge pdf's in xsl fo ? If yes, guide me.

 Thanks in advance

Re: PDF size reduction

[TvT]

Hi,

i agree with Michael - reducing the image size is the key.
We had this problem once with huge TIFF files which can (after scanning)
easily have a size of 50MB or bigger.
With the java image io we converted those pics into TIFF-G4 standard which
are greatly reduced in size (kb level).

Afterwards also our pdfs were much smaller. If you own Adobe Acrobat you can
try the effect of reducing the image quality / adding compression. Go to
Advanced/PDF-Optimization ...

  If you aren't bothered about image quality, then (albeit not knowing
 what format the image is currently) can you not use something like high JPEG
 compression on the graphics? This will dramatically reduce the image size
 and therefore the PDF size.

 Thanks.

 -Mike



 Well, it seems that my message was sent without content. I agree with
 Pascal: you can avoid to load the color profile. If this is not enough, you
 can try to process all the images via batch. There are several tools that
 can allow that. Try for example Image Magick...

Re: Footenote space / margin / distance / padding

[TvT]

Hi,

i read the specific part which confirms that the footnotes are part of
the region body. (The region-body has two conditional sub-regions
which implicitly specify corresponding reference-areas called
before-float-reference-area and footnote-reference-area.)

Possibly footnote-separators could be used to control the space
between footnotes however i am not sure whether FOP 1.0 supports
footnote-separators? There is nothing on the compliance page
http://xmlgraphics.apache.org/fop/compliance.html
and the mailing list entries for footnote-separators are quite old
(0.20.5 times)

Anyone knows something about it?

 Hi,

 i create a PDF file with a table and in some of the cells i use

 Sometimes if the table is big and continued on the next page, the last

 I played around with the regions, margins, padding, space.before and

 E.g. i tried:
 fo:footnote-body padding-before=4pt

 Initially i thought that footnotes are printed in the region-after
 however its seems that they are printed at the bottom of the

 Is there anyway to put some space between the footnotes and the last
 element?

Re: Filesize and embedded fonts

[TvT]

Hi Lui,

(in PDF) there is the possibility to subset a font - thus to only
include a subset of the font which you need.
Read here:
http://desktoppub.about.com/od/pdf/f/subsetfonts.htm

What you can do in FOP is described here:
http://xmlgraphics.apache.org/fop/1.0/fonts.html

There is a paragraph about 'Embedding' fonts and also a small part
about subsetting.
You are using TrueType Fonts?
When embedding TrueType fonts (ttf) or TrueType Collections (ttc), a
subset of the original font, containing only the glyphs used, is
embedded in the output document.

Check in the Acrobat Reader under File\Properties\Fonts that there are
only subsets of Fonts. If not try to change your font format. If the
subsetting worked then it will be difficult with plain FOP to reduce
the file size. Then you probably have to use a third party tool to
reduce the file size...

Regards,
ToM

PS:
One other thing, is there a special reason you are still using font
metric files? Since 0.95 this is usually not necessary anymore.

In earlier FOP versions, it was always necessary to create an XML
font metrics file if you wanted to add a custom font. This
unconvenient step has been removed and in addition to that, FOP
supports auto-registration of fonts, i.e. FOP can find fonts installed
in your operating system or can scan user-specified directories for
fonts. Font registration via XML font metrics file is still supported
and may still be necessary for some very special cases as fallback
variant while we stabilize font auto-detection.





2010/11/16 Tobias Luikard t.luik...@exxcellent.de:
  Hi everybody,

 since several years I use fop to produce PDFs. Now the request was to
 produce PDF/A documents. So I embedded all fonts necessary for the
 productions of the PDF.

 After some test and some errors I was able to produce PDF/A complient
 documents (at least FOP didn't throw any exceptions any more). But the
 problem is, that the size of the files increased 10 times (from 25,3 kB to
 248 kB).

 The fonts where embedded as True Type fonts in the fop.xml
 fonts
 font embed-url=XXFont.ttf kerning=yes metrics-url=XXFont.xml
 font-triplet name=XX style=normal weight=normal /
 /font
         ...
 /fonts

 I tried to convert the file with Acrobat. There the file size has grown but
 not that much. Does anyone have any suggestion how to reduce the file size?
 Do I make any errors when I include the fonts?

 The mass of file we have to put into the archive will be a problem when the
 file will be 1/4 MB of size...

 Thanks

 Tobi

 P.S. I'm using FOP 1.0, JDK 1.6.0_13 and Windows Vista

Re: Referring to a image file in a JAR file

[TvT]

Hi,

since the jar with our images was on the classpath we could reference
the image directly:

fo:external-graphic src=urn:some_logo.gif/

- urn: was the trigger for us in our resource resolver...

Regards,
ToM

2010/7/22 Bernard Giannetti thebernmeis...@hotmail.com:
 I already have a URIResolver implemented to resolve the something such as

     xsl:include href=pagesetup.xsl /

 which is what the Javadoc says it's used for:

 http://download.oracle.com/docs/cd/E17409_01/javase/6/docs/api/javax/xml/transform/URIResolver.html

 Unfortunately, the fo:external-graphic src=file://myapp.jar!/image.svg
 content-width=8 content-height=8 does not trigger the call to my URI
 resolver.  I have tried src=url() etc with no luck.  So either I've got
 the wrong format of the URL or it cannot be done this way.

 I don't see how to use xls:include, xsl:import and document (as per the
 Javadoc) to refer to the graphic file.  In your example, did you refer to
 images using fo:external-graphic or using some other tag?

 The other thing I noticed is I set my URIResolver on the TransformerFactory:

 SAXTransformerFactory saxTransformerFactory =
 (SAXTransformerFactory)TransformerFactory.newInstance();
 saxTransformerFactory.setURIResolver( myURIResolver );

 instead of on the foUserAgent which you did...so dunno if that makes a
 difference.

 Hi,

 we needed exactly that and implemented our own ResourceResolver for

 You can register it like the following:

 //Register a custom resolver
 foUserAgent.setURIResolver(new ClasspathResourceResolver());

 //The clas has to implement the URIResolver
 public class ClasspathResourceResolver implements URIResolver {

 //you overwrite the resolve method
 public InputStream resolve(String uri){

 //Resolves the path to a resource in the classpath (since that jar

 Hi,

 I am trying to refer to a graphic file within a JAR file.  The JAR file
 contains the application which is being executed along with the
 aforementioned graphic file.

 The application is launched via JNLP - so not sure if that effects what I am
 trying to do.

 If the JAR file is myapp.jar and the graphic is say image.svg then the tag

 fo:external-graphic src=file://myapp.jar!/image.svg content-width=8
 content-height=8 results in the error

 Error with opening URL 'file://myapp.jar!/image.svg'

 I have tried different variations on the src attribute, say file:/// and
 then also url('/image.svg') but with similar errors.

 Is it possible to reference an image file within the same JAR as the
 application?


 Thanks in advance,

 You could send me a small PDF example with which you have a problem and

   Hello everybody interesting in this

   after different test scenarios I have found solution to my

   is incomplete” I used ansi encoded font metrics (default
   by fop TTFReader is CID-keyed). Both validators shows no

   It is still open question why it is not working with

Re: Embedding PDF base into a FO document (at least for PDF output)

[TvT]

Hi,

 My goal is to be able to use (for
 instance) - a base pdf with a sheet pre-prepared with text and graphics, and
 overprint an address on the document, is that something within the
 capability of the library? Or is there another way to achieve this goal ?

We have done something similar with iText i guess:

There you can add a text to a layer above or below the normal text
layer (e.g. like a watermark)
You use getUnderContent() oder getOverContent Method and add your own
address, other text/images or whatever

(Regarding iText http://itextpdf.com - i would suggest you use the
version 2.1.7 since the new version has a changed license)

Regards,
ToM

Ps: Code like that:

//adds text to the first page
PdfContentByte underOverContent = this.stamper.getUnderContent(1);

underOverContent.beginText();
underOverContent.setFontAndSize(Font, FontSize);
underOverContent.showTextAligned(Element.ALIGN_CENTER,Some Text,X,Y,Rotation);
underOverContent.endText();
