Re: compressing pdf response

2005-09-20 Thread Sonja Löhr

Thanks to you all!

If the improvement is so small I will unplug the filter. Although the
browsers do support compression (the filter is checking this), the
outcome seems to be somewhat unpredictable, and I don't know anything
about the client side in production, of course.

 The browser explicitly asks if it will accept a compressed
 response. The server is *not* allowed to use compression (at the
 HTTP level) if the browser doesn't ask for it. Check your browser
 configuration. In Firefox, you might try the HTTP live headers
 extension for sniffing the actual values.
 
 Also, most of the PDF parts are already compressed (and re-encoded
 as ASCII85). A secondary compression will probably gain something
 between 15% and 20% for typical PDF files. Significant improvements
 are only to be expected in case of large embedded BMP images and in
 some cases if there are large embedded fonts.

compressing pdf response

2005-09-19 Thread Sonja Löhr

Hi!

This is not a FOP question, but you I'm sure you are familiar with these
things
I use FOP in a servlet and would like to add a CompressionFilter since the
output pdf is very large. 
I tried to get the output with firefox and IE the Browsers cannot handle the
output. (IE sometimes (?) can, firefox never.

The actual compression is that one:

gzipstream = new GZIPOutputStream(output);
flushToGZip();
response.addHeader(Content-Encoding, gzip);
response.setContentType(application/pdf);

I added the last line since I hoped it could help (additionally), but it
doesn't. Is there something else I could try to configure on any of the
Streams concerned? 

Before compressing, both browsers pass a test whether compressed data are
accepted.

Thanks for you help again!

 The article below, by Jason Hunter, discusses creating a

Re: upgrading from 20.0.5 to the trunk

2005-09-12 Thread Sonja Löhr

Ok, I can now answer some of my questions myself ;-)
I use the Fop class instead of the Driver class, right?
I'll try to change the code according to the source of FopServlet,
putting the extra steps somwhere between.

But some questions remain:

a) What about the configuration? I have had the following for
fop-20.0.5:
org.apache.fop.configuration.Configuration.put(baseDir,
ctx.getRealPath(/));
org.apache.fop.configuration.Configuration.put(fontBaseDir,
ctx.getRealPath(/WEB-INF/fonts));
org.apache.fop.configuration.Configuration.put(strokeSVGText,
false);  
File userConfigFile = new File(ctx.getRealPath(CONFIG_FILE));
new Options(userConfigFile);

b) My app already uses commons.logging with log4j. May I just do nothing
more and FOP will log onto the same appender as my servlet does?


Greetings!

Fop fop = new Fop(Fop.RENDER_PDF);
fop.getUserAgent().setUserConfig(conf);
.

or 
fop.getUserAgent().setBaseURL()
instead of specifying this inside the DefaultConfiguration?
(Font basedir is not essential since it is under baseDir)


Leaving now, I'll simply try tomorrow if no veto occurs ;-)

 Subject: (re:) pagination and width=100%
 
 Hi!
 
 Some days ago we talked about the problem of wrong 
 computation of table-widths if a break between two pages 
 occurs and the region-bodies (or
 column-widths) of these to pages differ in width.
 
 I use something like the following to keep the headline and 
 first paragraph of an article together. Actually, it is a bit 
 more complicated because not only ps may occur first, but 
 that shouldn't make a difference.
 
 
  xsl:template match=article
   !-- Headline and first paragraph --
   fo:block font-size=11pt space-after=0.6cm 
   fo:table table-layout=fixed  width=100%
   fo:table-column
 column-width=proportional-column-width(1)/
   fo:table-body 
   fo:table-row keep-with-next=always
 keep-together=always
   xsl:apply-templates
 select=headline mode=content/
   /fo:table-row
   fo:table-row keep-together=always
   
 fo:table-cellxsl:apply-templates
 select=p[1]//fo:table-cell
   /fo:table-row
   /fo:table-body
   /fo:table
   xsl:apply-templates select=p[position() gt; 1]/
 
   /fo:block
 /xsl:template
 
 
 The evil part is that one (shortened):
 
  fo:simple-page-master master-name=first page-height=29.7cm
 page-width=21cm
 margin-top=0cm  margin-bottom=2.2cm  
 margin-left=2.5cm
 margin-right=2.5cm
  fo:region-body margin-top=7cm margin-bottom=0cm
 margin-left=7cm/ 
fo:region-before precedence=true region-name=first-before
 extent=7.5cm/ 
fo:region-start region-name=first-start 
 extent=5.6cm/  /fo:simple-page-master
 
 The other fo:simple-page master objects don't have this 
 region-start and therefore don't have such a big left margin 
 on their region-body. (There is a box containing the the 
 contents on on the left of the first page).
 
 So what happens is that if there really has to be a 
 page-break from page 1 to page2 when a new article starts, 
 the headline-p1-table will have the width of the first page's 
 region-body. 
 After that headline-p1-table everything is fine.
 
 Hmm, my customer was so sold on that content-box on the left 
 side ;-), in the end I will have to remove it...
 
 
 Greetings and many thanks!

Re: Pagination Problem

2005-08-19 Thread Sonja Löhr

Hi!

I can't help ;-(, but for those who can, I just want to add a related
observation:
I put each headline in a table together with the following paragraph,
with keep-with-next and keep-together, the table should have a width of
100%.
If a page break occured before such a table (and only then), FOP seemed
to not recognize it early enough: The table indeed displayed on the next
page, but the percentual width is  100% of the width in the previous
page.

(I used 2 columns on pages greater than 1 and some box in region-start
of the first page, so the text-width differed.)

Re: Pagination Problem

2005-08-19 Thread Sonja Löhr

Thanks, Jeremias!

My customer finally prefered a one-column layout, so I didn't see the
error again. But theoretically, it could still occur, since the first
page still has this box in its region-start. 
If I revisit that project in the next days, I'll try to reproduce the
error and get an output of the FP tree - by the time I wait for other
errors to be reported by my customer ;-)

 Sonja's problem seems to be something else. It would help to have an FO
 file to reproduce it. Anyway, the thing she describes will not be
 possible for some time with the development code (for the devs: changing
 available IPD problem). This is quite tricky stuff for us coders. To
 avoid any problems you should put the headline page and the following
 pages in a different page-sequence and try not to have to flow content
 from the first to the second page. That should work for both FOP
 versions.

RE: Relative URLs

2005-08-13 Thread Sonja Löhr

Hi!
First of all: You are really a great mailing list!! 
Helpful comments almost immediately, every time :-)

Setting the basedir in the config file is working - thank you!
It is no perfect solution as I still have to once more note the installation
directory, but I already reference my fonts that way and get along setting
CATALINA_HOME for Ant ... 
Passing request.getServerName (and perhaps request.getServerPort()) is what
I would have used... indeed, I already do something similar in a
preprocessing step (for the simulation of floats) to manage Server (not
tomcat)-relative URLs.

Being interested generally, if anybody knows/finds the default of this
basedir in a servlet environment where no real fo files are written, please
let me know!

Regards,
sonja

 You'll probably need to set the baseDir in the FOP configuration.
 See
   http://xml.apache.org/fop/embedding.html#config-internal
 Try getRealPath(/) on the servlet context in order to get a 
 useful file system path.

RE: Relative URLs

2005-08-13 Thread Sonja Löhr

Ah! I misunderstood you. Yes, if I do the configuration programmatically
instead of my fop-config.xml, of course I have dynamic access to everything!
Great, I'll check now if I could reference font-metrics and embedded fonts
this way as well.

Thank you VERY much!

RE: Relative URLs in Servlet-created FO

2005-08-13 Thread Sonja Löhr

Mike (and others),

I'm now very content with my configuration and will summarize it shortly:
The configuration xml is now very short:

configuration
fonts 
font metrics-file=font1.xml kerning=yes
embed-file=../ttf/Ss__.ttf 
  font-triplet name=customFont style=normal weight=normal/
/font
font metrics-file=font1_b.xml kerning=yes
embed-file=../ttf/Sssb.ttf 
font-triplet name=customFont style=normal weight=bold/
/font
/fonts
/configuration

and my Servlet's init() starts with

 ServletContext ctx = getServletContext();
 new Options(new File(ctx.getRealPath(CONFIG_FILE)));
 org.apache.fop.configuration.Configuration.put(baseDir,
ctx.getRealPath(/));
 org.apache.fop.configuration.Configuration.put(fontBaseDir,
ctx.getRealPath(/WEB-INF/fonts));

The logo is referenced inside the stylesheet with:

fo:external-graphic src=url(headers/logo2.svg) /

 (headers being a directoy under the context root, fonts and ttf are
under WEB-INF)


Greetings and thanks again,
sonja

 Subject: Re: Relative URLs
 
 I had some similar problems last year - but can't remember 
 how I solved them.
 I have a nasty feeling that I ended up passing server names 
 etc. as XSLT parameters.
 
 I also had problems between a version of XEP and FOP in their 
 interpretation of url() contents - which differed.
 
 The resolution of url() paths may depend on when they are 
 processed (i.e which document) and by what.
 So - the paths should be processed relative to the location 
 of your FO file.
 
 If the FO file is produced in memory - then the relative base 
 probably depends on the application.
 You could try using the 'xml:base' attribute on an element in 
 the FO to define what should be taken as the base url for 
 that element and child elements - but I haven't tried this with FOP
 - so don't know if it works / is supported.
 
 I too will be interested to see any helpful comments on this.

 All my fonts in place, I still seem to be not fit enough for

 I now try to replace an absolute URL on an external-graphic element 
 with a relative one. FO is created via XSLT,  and my 
 stylesheet resides 
 in a subfolder of WEB-INF. In- and OutputStreams before and 
 after, but 
 that shouldn't matter.
 fo:external-graphic
 src=http://localhost:8080/pdfnewsletter/headers/logo.svg/ 
 is working 
 well here, but I cannot be sure whether the production server will 
 really be listening to localhost.
 What did I try? 
 a) referring to the svg in its original place outside WEB-INF with
 url(/headers/logo.svg) - context-relative, url(headers/svg),
 url(../../logo.svg) and so on - also with single quotes 
 around the paths.
 b) Putting the graphic (an svg) in the stylesheet's directory and 
 referring to it with url(logo.svg)
 c) Putting the graphic inside the package of the 
 transforming servlet, 
 which ends up in a jar file, and again referring with url(logo.svg)
 
 Some of these trials where really odd, I always tried to 
 refer to the 
 execution of my servlet as base.
 
 Please help once more - thanks!!

RE: Font embedding again

2005-08-06 Thread Sonja Löhr

Hi, Jeremias!
Thank you for answering!
 Nevertheless, in my servlet, I hand over my own logger to the fop-driver
Here is the normal log if I don't use special fonts or if the path to ttf
is simply wrong:
(this is the webapps log, since I hand over the servlets logger to the fop
driver).

[some logging of my Servlet code before fop comes into play]

When embedding the font, the log looks like this:

[some logging of my Servlet code before fop comes into play]
06 08 08:26:17 INFO   com.dietzk.fo.FopTransformServlet (73) - building

06 08 08:26:27 INFO   com.dietzk.fo.FopTransformServlet (73) - [1]

nothing more. With some modifications on the paths not even the two [1]
lines show up.
There is no tomcat error message on the screen but simply a transparent
browser tab on firefox and in IE the 404 error page. (But the webapp was
found and run)  
In tomcat logs, I don't find any error message either.


And here is the current version of fop-config.xml (I tried a lot with
windows path and URI versions:

font
metrics-file=file://D:/Programme/Tomcat-5.5/webapps/pdfnewsletter/WEB-INF/f
onts/font1.xml kerning=yes
embed-file=E:\sonja\projekte\mainovaJ5\etc\fonts\Sssb.ttf
  font-triplet name=customFont style=normal weight=normal/
/font
font
metrics-file=file://D:/Programme/Tomcat-5.5/webapps/pdfnewsletter/WEB-INF/f
onts/font1_b.xml kerning=yes
embed-file=E:\sonja\projekte\mainovaJ5\etc\fonts\Ss__.ttf
font-triplet name=customFont style=normal weight=bold/
/font

No better if I change to forward slashes in the embed-file attribute. It
works well with tomcat 4.1.24 under Windows. For the win/linux problem: I
haven't yet tried tomcat 5.5 under Linux, only 5.0.30 ;-)
If I tried even more tomcats and learn more at least for the statistics ;-),
I'll write again.


Thanks again!
sonja

 Funny. Some people have no problem on Windows and when they

 Hmm.
 
 So, Sonja, did you check all the log output closely? Any

 And no, it won't help if you try the code directly from

Sorry, forgot to tell you: No, I don't use a fontBaseDir.  The fonts element
with the contents I just posted is the only element inside configuration
in fop-config.xml.
Perhaps these infos are also important (but all ok with that very old
tomcat):
- I rebuilt FOP with an extra german hyphenation file 
- As already mentioned, the font metrics file(s) where created under Linux.

Bye!

RE: Font embedding again

2005-08-06 Thread Sonja Löhr

Got it!!
It was not the embed-file attribute, but the metrics-file attribute itself.
Although I'm quite sure to have  tried all numbers of slashes and
backslashes, it is finally ok with:

font
metrics-file=file:///D:/Programme/Tomcat-5.5/webapps/pdfnewsletter/WEB-INF/
fonts/font1.xml kerning=yes
embed-file=E:/sonja/projekte/mainovaJ5/etc/fonts/Ss__.ttf
  font-triplet name=customFont style=normal weight=normal/
/font

Perhaps something was overwritten, as the attribute values are inserted via
ant location properties 

Sorry for all the mailing and happy fopping !
