I used to work with DICOM ( video archiving of cardiac
images ) - yes, it's possible to extract those data. 

But there are a *lot* of possible image formats,
and transfer syntaxes...
In  my field it was mostly loseless JPEG - and I have
developed a lot of tools in this field, but not in
java.

And I doubt that there is ready and open source tool
for conversion of loseless JPEG - not very common...

Right, as in Digital Imaging and Communications in Medicine.
Yes, I've seen some folks on the JAI-interest list (Java Advanced Imaging)
state they have done exactly that--convert them to jpeg on png.

You mean DICOM? Medical imaging? Which modality?
I think you will have to extract them and convert
image data to some sane format befire includeing
them into pdf.

Re: dicom images

[Jeremias Maerki]

Neither JIMI, nor JAI support DICOM out of the box, as far as I know.
So the first task is to find an image library or JAI/ImageIO plug-in
that supports DICOM. The second would be to write an implementation of
the ImageReader interface which can be found in the package
org.apache.fop.image.analyser.

Re: Status of the Postscript Renderer

[Jeremias Maerki]

I've tried to track down the problem but I don't have a clue at the
moment. I've added a Bugzilla entry for this so this doesn't get lost:
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=20506

In the meantime I suggest trying another image format. The image you
sent me off-list would be better suited as EPS or SVG anyway if you ask
me.

I will look into this, 

 

one question though how do you use the font in the ps file,  do you embed it in FOP, or somehow embed it
in the ps file afterwards ?

Hello: 

    I am trying to render a document that
utilizes "ocraext.ttf" for one line on the document for bill paying.
I was able to add the font into FOP, do the configuration and get it to
work...sort of. When I render in PDF I can see the line in the document in the
correct font, when I render to PS I can not even see the line. After much
reading and searching I have come to discover that ttf is not supported in the
ps renderer. My question(s) are this:

1) has anyone created a work around ? 

2) is there a way,  post processing,  to
"define" the font in the postscript file. Can I "manually"
alter the ps file, before sending it to the printer, that is can I imbed the
definition of the font in the ps file, then alter the file where I need to and
make the line appear in the correct font.  

Currently, I need to stick to PS files because in the
PS document I inject = "statusdict begin 0 setpapertray" to select
the paper tray as there is no way to do this within FOP or the style-sheet. 

3) If I figure out away to print the PDF directly I
will render to PDF, but I have to set a tray command on the document, and I
don't know how to do this for a PDF doc. In addition to this I use some of the
contents of the PS doc to gather metrics (ie number of pages, sent to printer
etc...)

Is there a way to "inject" this command into
a PDF doc. And is there a way to get the page-count of a PDF doc?


Sorry for the long windedness... and the potential
confusion

Inserting zero width spaces at the right spot will trigger wrapping.
Search the archives of FOP user & XSL lists for "zero width space", it's a

Re: Running FOP from Java

[Jeremias Maerki]

Look at createPreviewDialog(): There's a WindowListener being added that
performs System.exit(0). You need to change that, obviously.

Re: FOP and user load?

[Jeremias Maerki]

That really depends on a lot of things:
- how you implement it (maybe some PDF can be cached and reused)
- what hardware you run it on
- the complexity of your stylesheets (forward references, tables etc)
- etc etc.

You might want to use a load-testing tool figure that out. JMeter might
be an idea: http://jakarta.apache.org/jmeter/

Re: PDF form fields with FOP or other way

[Jeremias Maerki]

Jörg recently answered that:

I don't think you can expect that feature in the near future. Search the
mailing list archives. There have been discussions about that in the
past. Maybe they provide some additional insight.

That's correct.

Not to my knowledge. I've made a time estimation on this for someone
recently, but they didn't want to pursue.

If the work-around below doesn't work for you, you have several options:
- This is OpenSource, you can do it yourself.
- This is OpenSource, you can wait until someone has free time and thinks
  this is fun to implement.
- You can find/hire someone to do it for you.

What you want to do is not so simple. You could just as well implement
TrueType support in the PostScript renderer.

The obvious work-around is to use the PDF renderer and use GhostScript
to do a PDF to PS conversion. Works fine, but will result in a
performance penalty (around 40-50% additional time per document).

There's no standard way to embed information like paper tray into a PDF
document. An embedded or associated jobticket might provide a solution
but that always depends on your printer. After all, your printer needs
to have a PDF RIP in the first place.

The page count of a PDF doc can easily be determined by using a
third-party PDF post-processing tool like iText.
http://xml.apache.org/fop/resources.html#products-pdf

Also, FOP gives information about the number of pages rendered as
described here: http://xml.apache.org/fop/embedding.html#render-info

> Sorry for the long windedness... and the potential confusion

No confusion, I know exactly what you're talking about. I have gone
through it all. :-)

Having written all that I went over it again and reread your first
paragraph and I got an idea: Install that OCRA font on your machine and
use SVG to write that single line of text. Make sure you have
strokeSVGText set to true. I haven't tested this here but maybe, maybe
it could work. Background: Batik will convert the text to shapes which
get painted in the PostScript file. No font support needed. Maybe. Good
luck.

Re: Eps image error : For input string: ""

[Jeremias Maerki]

There's probably something strange with your EPS file. If you run again
with the -d option on the command line you get a full stacktrace which
should give us more information what exactly is wrong because I can't
find the "For input string" error message anywhere in the code. You can
also send me (off-list) your EPS and I'll have a look at it.

Re: Status of the Postscript Renderer

[Jeremias Maerki]

Can you post a little (!) JPEG image that's causing you trouble (or send
it to me off-list)? I've just checked with every special JPEG image I
have available here and haven't seen any problems. All show fine in
GhostView.
