Hi,

I have a high resolution image that is 450x450 dpi and 3983x5524 pixels

When adding this it a pdf with IText i use scalePercent();

I use 72 / 450 * 100 and it's 16% scale. When indesign does this the same
image is 3912x5454 pixels 450x450 dpi. can anyone give me a hint on how to
produce the same size?

Subject: [iText-questions] performance follow up

Hello,

Good news ... after applying the attached patch to trunk and doing yet another 
performance experiment using the previously posted workload these are the 
results:

BEFORE (trunk)
MeanVariance
15.125  5.514
15.440  3.474
15.258  9.736
15.621  23.869
15.449  4.817
15.500  2.662
15.221  8.431
15.319  3.419
15.142  1.626
15.457  3.972

AFTER (trunk + patch)
MeanVariance
14.404  5.928
14.487  16.781
14.132  1.618
14.314  3.174
14.663  7.522
14.542  15.086
14.283  6.924
14.399  2.064
14.205  1.609
14.471  2.761

The mean values look surprisingly much better than in the office. I'm running 
here Snow Leopard with JVM 1.6.0_19.

Is iText with the patch better than before?

The paired observation of the means are:
{(15.125, 14.404),
(15.440, 14.487),
(15.258, 14.132),
(15.621, 14.314),
(15.449, 14.663),
(15.500, 14.542),
(15.221, 14.283),
(15.319, 14.399),
(15.142, 14.205),
(15.457, 14.471)}

The performance differences constitute a sample of 10 observations:
{0.721, 0.953, 1.126, 1.307, 0.786, 0.958, 0.938, 0.92, 0.937, 0.986}

For this sample:
Sample mean = 0.9632
Sample variance = 0.02651
Sample standard Deviation = 0.16282

Confidence interval for the mean = 0.9632 +/- t*sqrt(0.02651/10) = 0.9632 +/- 
t*0.0514
The 0.95 quantile of a t-variate with df=N-1=10-1=9 is 1.833113
= 95% confidence interval = 0.9632 +/- 1.833113*0.0514 = 
[0.9632-0.09422,0.9632+0.09422] = [0.86898,1.05742]
Since the confidence interval does NOT include zero we can conclude that the 
performance improvement is significative (patch is better than no patch) and 
will be approximately of (0.9632/15.3532)*100% = 6.2%

I also ran the workload connected to the profiler and the number of 
StringBuffer instances decreased to 846'988

The Letter PDF looks good i.e. the patch didn't seem to break anything but you 
will have to run the unit tests on it.

Best regards,
Giovanni

PS: There are still some StringBuffer around to fix ...

Is iText with the patch better than before?

This of course is where you consult Mark Twain. LOL.
iText is or isn't better than before ( for some particular
use case) irrespective of the data you currently have
but the question is does the data allow
you to reject the conclusion that they are have the same
execution times with some confidence level?

Finding ways to explain or attribute the noise into somekind
of model of course would be a reasonable thing to
consider if you had a few more test cases with some
relevant parameters( number of fonts you will need or something).
The statistics are just a guide to help you
infer something causal- in this case perhaps something
like, did the patch cause itext to get better? as you
suggested originally. If you can start describing where and how much it got
better,
response surfaces I guess, then of course you are starting
to develop strategy logic, and could take a given task and feed
it to the patched or non patched version ( among a new family
of altnerative implementations) depending on
the parameters you know about it- obviously for the cases
you have only one decision makes sense andd off hand based
on what you said about nature of patch I don't know of any
case where generating gratuitous garbage is a good strategy LOL.

The paired observation of the means are:

At this stage
it is usually helpful to look at the data, not
just start dumping it into equations you found in a book.
I'm not slamming you at all, just that its helpful
to have a check on your analysis even if you
are using something canned like Ror a commercial package,
more so if you just wrote the analysis stuff today.
Don't ignore things like histograms etc, after all my
criticisms of PDF for its ability to obscure information
with art, sometimes there are pictures worth a thousand words.
And of course using the pictures to suggest
various sanity checks you can write.

The Letter PDF looks good i.e. the patch didn't seem to break anything but
you will have to run the unit tests on it.

LOL, often people forget this step.

Also it sounds like the alt pacakage is still faster by
a clinically significant amount- an amount relevant to someone.
There may be more coding optimiztions or algorithmic optimizations.
for example, converting a string to a byte array could
have some benefits, hard to know off hand since that
may incur more java code then native code to manipulate
but something to consider in a more general case.
With a byte array you may be able
to avoid creating lots of temp string, just make an int
table of the locations of new tokens or pass around indexes
instead of temp token strings. etc etc

  hi,

Maybe this has been answered before...
Is there a Python wrapper for the iText DLL that allows me to issue  
iText(Sharp) calls, under Windows?
I'm using Python 2.5

Subject: [iText-questions] PdfWriter.getPageNumber() is returning next 
page number when table ends at the end of page

I am trying to display mutiple tables in a single PDF and display page X 
of Y 
at the end of each page. 
X, Y should reset for every new table(Basically every new table should 
start 
with a new page.) 
Each table can vary and span accross multiple pages. 

I don't have problem while tables end in the middle of page(1 page of 
multiple pages). 
The problem comes when the table size matches page size. 

If a table size is approximately equal to page size. 
it displays page 1 of 2, when it has only one page. 

For tables ending in the middle of page, if it has 3 pages, page numbers 
are 
displayed correctly as 
1 of 3 , 2 of 3 , 3 of 3. But when table size ends at the end of page, if 
there is 1 page, still it display 1 of 2. 

Please note, the number of data tables is dynamic . 
 
public class DocumentEventListener implements PdfPageEvent { 
PdfTemplate m_Template; 
BaseFont m_BaseFont; 
PdfContentByte m_Cb; 


public void onEndPage(PdfWriter writer, Document arg1) { 
try { 

final int page = writer.getPageNumber(); 
String text = Page  + page; 
m_BaseFont = 
BaseFont.createFont(BaseFont.HELVETICA, BaseFont.CP1252, 
BaseFont.NOT_EMBEDDED); 
m_Cb = writer.getDirectContent(); 

if(m_Cb!=null){ 
m_Cb.beginText(); 
m_Cb.setFontAndSize(m_BaseFont, 8); 
 m_Cb.showTextAligned(PdfContentByte.ALIGN_RIGHT,text,410,20,0); 
m_Cb.endText(); 
m_Cb.addTemplate(m_Template, 352.3f, 20); 
} 
} catch (DocumentException e) { 
// TODO Auto-generated catch block 
e.printStackTrace(); 
} catch (IOException e) { 
// TODO Auto-generated catch block 
e.printStackTrace(); 
} 

} 

public void createNewTemplate(PdfWriter arg0){ 

m_Cb = arg0.getDirectContent(); 
m_Template = m_Cb.createTemplate(85,140); 


} 


public void fillOutTemplate(PdfWriter arg0) { 
try { 
// arg0.reorderPages(null); 
m_BaseFont = 
BaseFont.createFont(BaseFont.HELVETICA, BaseFont.CP1252, 
BaseFont.NOT_EMBEDDED); 
m_Template.beginText(); 
m_Template.setFontAndSize(m_BaseFont, 8); 
String text = of  + (arg0.getPageNumber() ); 
 m_Template.showTextAligned(PdfContentByte.ALIGN_LEFT, text, 65, 0, 0); 
m_Template.endText(); 
} catch (DocumentException e) { 
// TODO Auto-generated catch block 
e.printStackTrace(); 
} catch (IOException e) { 
// TODO Auto-generated catch block++ 
e.printStackTrace(); 
} 
} 

}

Re: [iText-questions] re solution images indesign-server my implementation


never mind, the itext approach is correct. It is a 3 party that integrates
with indesign-server så it must be some fit-in-block that makes this
oddness.

[iText-questions] problem with rounded corners


Hi, I have problems with rounded corners. If I use the cb directly here and
don't create a Pdftemplate everythings works fine with the rounded corners
but if the background I set every block in my page will get them.

cell.setCellEvent( new PdfPCellEvent(){
  public void cellLayout(PdfPCell cell, Rectangle rect,PdfContentByte[]
canvas) {
  // Here I have tried to just add it to the PdfContentByte but then every
block 
  // is the color of the last block. I've tried cb.saveState() and
restoreState() but without luck 
  PdfContentByte cb = canvas[PdfPTable.LINECANVAS];
  PdfTemplate template = cb.createTemplate( rect.getWidth() ,
rect.getHeight());

  if( getBorder() != null ){
template.setLineWidth( MeasurementUtil.millimetersToPostscriptPoints(
getBorder().getThickness()) );
template.setColorStroke( getPage().getPdfDocument().getColors().get(
getBorder().getColorReference() ));
  }

  if( getBackgroundReference() != null ){
template.setColorFill( getPage().getPdfDocument().getColors().get(
getBackgroundReference() ));
  }

  template.roundRectangle(0 , 0, rect.getWidth() ,rect.getHeight() ,
MeasurementUtil.millimetersToPostscriptPoints( getRadius() ));

  if( getBackgroundReference() != null || getBorder() != null ){
if( getBackgroundReference() != null  getBorder() != null ){
  template.fillStroke();
}else if( getBackgroundReference() != null ){
  template.fill();
}else{
  template.stroke();
}
  }

  cb.addTemplate( template, rect.getLeft(), rect.getBottom());
}});

Re: [iText-questions] What action is requred in terms of License

If it's all done in the intranet by the employees you won't need a license, 
what you do afterwards with the PDFs is irrelevant. If you expose the service 
to the internet, even if it has a restricted access only for employees, than 
you'll need a license as the potential access is universal. By the way, I'm not 
a lawyer nor an employee of itextsoftware so, this is my, not legal binding, 
opinion. Doubts with so many questions should be addressed to itextsoftware and 
your company's lawyer.

In our case, we will have a Websphere running on the server side with iText 5 
jar file, our intranet employees will use browsers to view and print the pdf 
files generated by the iText, then send the printed the document to external 
users.

Do we need a commercial license in this case?

page number when table ends at the end of page 
I am trying to display mutiple tables in a single PDF and display page X 
of Y 
at the end of each page. 
X, Y should reset for every new table(Basically every new table should 
start 
with a new page.) 
Each table can vary and span accross multiple pages. 

I don't have problem while tables end in the middle of page(1 page of 
multiple pages). 
The problem comes when the table size matches page size. 

If a table size is approximately equal to page size. 
it displays page 1 of 2, when it has only one page. 

For tables ending in the middle of page, if it has 3 pages, page numbers 
are 
displayed correctly as 
1 of 3 , 2 of 3 , 3 of 3. But when table size ends at the end of page, if 
there is 1 page, still it display 1 of 2. 

Please note, the number of data tables is dynamic .

You should at least try 2.1.7. If that doesn't work you are on your own unless 
you buy a license and support from itextsoftware. The mailing list only gives 
support to the latest release.

Re: [iText-questions] problem with rounded corners

PdfTemplate extends PdfContentByte, there's no reason why the results shouldn't 
be the same. It would be helpful to see a pdf with those differences.

Re: [iText-questions] Mergin pdfs

2010-04-22 Thread jdhankins



I've modified your code a bit and have a question.  I have a single page pdf
with a form (attached as rider_release.pdf).  In my database, I have 100's
of entrants (first name, last name, etc..), each of which, need to be
completed on the form in the rider_release file.  I am trying to take the
original document, open it, and while looping through my entrants, populate
the form and concatenate to the previous page.  So, in the end, I will end
up with a 100+ page pdf, each page containing the same page with the
exception of the form data.

I've attached the concatenatedPDF file so you can reference my output from
the code below.  Notice how all pages are empty.  The first page still
retained the form, while the other two pages did not.

Please help when you have time.

// begin code

// original document (release form for bike riders)

reader.consolidateNamedDestinations();
document = new Document(reader.getPageSizeWithRotation(1));

// my result document of all race waivers concatented
writer = new PdfCopy(document, new
FileOutputStream(c:/temp/concatenatedPDF.pdf));
writer.setViewerPreferences(PdfWriter.PageModeUseOutlines);

document.open();

// simulate looping through 3 bike riders
int i = 0;
while (i++  3) {

reader = new PdfReader(c:/temp/rider_release.pdf);
reader.consolidateNamedDestinations();
ByteArrayOutputStream baosPDF = new ByteArrayOutputStream();

// the only way to change the form is with a stamper...?
PdfStamper stamper = new PdfStamper(reader, baosPDF);

AcroFields form = stamper.getAcroFields();
form.setField(Phone, 402-555-1212);

Re: [iText-questions] problem with rounded corners


Hi,

Yes I'm sure that there is something in my code making this but I can't find
it. I have now managed to remove the sharp edges to smoth but with very odd
settings. I must create a round rectangle twice to make it work.

@Override
public void onRender( PdfContentByte cb ) throws PdfDocumentException{
  float width = MeasurementUtil.millimetersToPostscriptPoints( getWidth());
  float height = MeasurementUtil.millimetersToPostscriptPoints( getHeight()
);
  float left = getLeft();
  float top = getTop();
  if( getPage().getPdfDocument().getCutMark() != null ){
left += getPage().getPdfDocument().getCutMark().getWidth();
top -= getPage().getPdfDocument().getCutMark().getHeight();
  }

  PdfTemplate tp = cb.createTemplate(width, height);
  tp.roundRectangle(0, 0, width, height,
MeasurementUtil.millimetersToPostscriptPoints( getRadius() ));
  cb.addTemplate(tp, MeasurementUtil.millimetersToPostscriptPoints( left ),
MeasurementUtil.millimetersToPostscriptPoints(
getPage().getPdfDocument().getHeight() - ( top + getHeight(;
  ColumnText ct = new ColumnText( cb );
  ct.setSimpleColumn( MeasurementUtil.millimetersToPostscriptPoints( left ),
MeasurementUtil.millimetersToPostscriptPoints(
getPage().getPdfDocument().getHeight() - ( top + getHeight())),
MeasurementUtil.millimetersToPostscriptPoints( left + getWidth() ),
MeasurementUtil.millimetersToPostscriptPoints(
getPage().getPdfDocument().getHeight() -  top ), 0, Element.ALIGN_LEFT );

  PdfPTable table = new PdfPTable(1);
 
table.setTotalWidth(MeasurementUtil.millimetersToPostscriptPoints(getWidth()));
  table.setLockedWidth( true );
  table.setSpacingBefore(0);
  table.setSpacingAfter(0);
  PdfPCell cell =  new PdfPCell();
  cell.setBorderWidth( 0 );
  cell.setVerticalAlignment( getVerticalAlign().getAlignment() );

You didn't read the most documentation.

 I've attached the concatenatedPDF file so you can reference my output from
 the code below.  Notice how all pages are empty.  The first page still
 retained the form, while the other two pages did not.

Do you want to keep the form?

If not, you should flatten the fields,
and then use PdfSmartCopy instead of PdfCopy.

Do you want to keep the form?

Then you need to rename the fields for every page,
and then use PdfCopyFields instead of PdfCopy.

Please look at the examples of chapter 6 and chapter 8
of the second edition of iText in Action.

2010-04-22 Thread Michael Olenick

If you're making money from iText -- with making money being defined
as somebody is paying you -- you should pay for it.  There's a lot of
hard work that went into the creation and support of this awesome
tool.

The licensing scheme they have for v. 5.0 is already incredibly
generous; too generous IMO.  Bruno and the team deserve to be paid for
their work.  If you're a University or not-for-profit or a start-up
tell them: I'm sure they'll work out licensing arrangements that work
within reasonable constraints; they don't want to put anybody out of
business.

Re: [iText-questions] Where can I get the current horizontal positionwithin ColumnText/PDFWriter?

peter.henning...@wcenter.de wrote:
 I see two other options to implement the desired functionality:
 
 - put code into ColumnText.go() to generate an event whenever the column 
 if full or the text ends. Then pass the current position in that event 
 object
 - change ColumnText, so the current position can be obtained with getXPos()

After reading the initial question, I interpreted it the same way as 
Paulo. Reading your follow-up, I see that generic tags probably won't 
help: you don't know in advance where the column will split.

I've looked at the code very briefly (I'm sorry, I really don't have
much time this week), but maybe the method writeLineToContent in
PdfDocument should return an X value that can be captured by ColumnText.

What you need is PdfLine.getLeft() + PdfLine.GetLineLengthUtf32() of
the last line that is added. However, if there is glue in the line,
or if the line is justified, the method writeLineToContent will add
extra spacing.

Post a reply to the list if you don't have the time to look at this
before Sunday. Maybe I'll find some time to work something out then,
or you can share your experience if this (very premature) suggestion
leads nowhere (in which case, I'll have to think of another way to
achieve what you need).

Re: [iText-questions] What action is requred in terms of License

2010-04-22 Thread Michael Olenick

Then tell them what the project is and what you can afford.

Seriously -- that applies for all software components.  If you're
working for a Fortune 1000 call the person who licenses software and
ask them to work something out.  If you're working for a smaller
company, or on your own, know that if you talk to virtually any
software company they'll work within your budget constraints, as long
as those constraints are reasonable.  That's not just the itext
licensing partner but Oracle, Microsoft, IBM ... as long as you're not
BS'ing them they'll all work with you.  They want you to do well so
that you use their product in bigger projects, or pay them more as you
grow.  They make nothing if they demand fees you can't pay and don't
use their product(s).  Since the incremental cost for software is
virtually zero there's little to lose and lots to gain once you're
locked-in.  [Conversely, for the younger engineers here, be careful
who you lock-in with ... divorces in software are worse than divorces
in real life.]

That's very interessting: I am working both in research at an university and

magnitudes beyond the complete project budgets with very strict obligations.
I am really willing to obtain a license and to pay several 100 $ for it and
I find it absolutely ok for the developers to earn money with their
fantastic library. But: The current license fees are affordable for big
industries only. I already thought about stopping to use iText or to stick

component only, and I am not willing to report the number of distribution

Re: [iText-questions] What action is requred in terms of License

2010-04-22 Thread Christoph Wagner

Hi,

 The license fees were magnitudes beyond the complete
 project budgets with very strict obligations. I am really willing to
 obtain a license and to pay several 100 $ for it and I find it
 absolutely ok for the developers to earn money with their fantastic
 library. But: The current license fees are affordable for big
 industries only. I already thought about stopping to use iText or to
 stick with 2.1.7. After all,within my programms  this is only a small
 component for generating reports in order to show the results of
 computation processes. I think, there are a lot of small projects and
 developers who are in the same situation. If there is another way, I

 whole budgets on the reporting component only, and I am not willing to
 report the number of distribution number several times a year. Have you
 ever thought about single developer licenses with no fees for
 redistribution?

That's an interesting topic. Just being curious: What's the amount to pay
for a commercial iText license? We had the same problem and decided to fork
iText 2.1.7. We are also heavily working on that base trying to refactor all
these bad little things out of the code and applying additional fixes. I
would happily pay some money to get a lib and support but with the currently
non-existent professional support for iText asking for money does not
represent the state of the project at least to me.


Just my 2c,
Campus

 you have only one decision makes sense andd off hand based
 on what you said about nature of patch I don't know of any
 case where generating gratuitous garbage is a good strategy LOL.
 
I know ... but hypothetically my patch could have well fixed the generating 
gratuitous garbage while the use-case still be slow i.e. my point being to make 
sure and prove that the patch delivers the promised performance gain.

 The paired observation of the means are:
 At this stage it is usually helpful to look at the data, not
 just start dumping it into equations you found in a book.
 
This book is the official reference for the course in Advance System 
Performance Analysis I am taking for my graduate CS Master program in the 
top-10 Technology University of the world ... so no, it is not just equations I 
found in a book :)

If you need to compare the performance of two systems and you have paired 
observations, this is the recipe you want to use. 

  I'm not slamming you at all, just that its helpful
  to have a check on your analysis even if you
 
No worries, I am actually very happy with your feedback. I would actually like 
to thank you for your insights. 

 Also it sounds like the alt pacakage is still faster by
 a clinically significant amount- an amount relevant to someone.
 
Now only 23.8% to go. We only need to make 4 more fixes like the last one and 
the gap will be gone :) The Profiler shows there are still several bottlenecks 
topping which could also be easy fixes e.g. PRTokeniser.isWhitespace is a 
simple boolean condition that just happen to be called gazillion times e.g. 
35'622'000 times for my test workload ... if instead of doing it like:

public static final boolean isWhitespace(int ch) {
return (ch == 0 || ch == 9 || ch == 10 || ch == 12 || ch == 13 || ch == 32);
} 

we used a bitwise binary operator with the appropriate mask(s), there could be 
some good performance gain ...

I like your approach!  A simple if (ch  32) return false; at the very top
would give the most bang for the least effort (if you do go the bitmask
route, be sure to include unit tests!).

I know there were a lot of calls to this method, but I'm curious:  in your
pofiling, how much of the total processing _time_ was spent in that routine? 
The if() would make this 6 times faster, but it's hard to believe that this
call has any appreciable contribution to runtime.

Keep it up!

The semantics are different (the JSE call includes more characters in it's
definition of whitespace than the PDF spec).  Not saying that it can't be
easily done, but throwing an if statement at it and seeing what impact it
has on performance is pretty easy also.

What was the overall time %age spent in this call in your tests?

does this have to be int vs char or byte? I think earlier I suggested
operating on byte[] instead of making a bunch of temp strings
but I don't know the context well enough to know if this makes sense.
Certainly demorgan can help but casts and calls are not free either.
 
Also, maybe hotspot runtime has gotten better but I have found in
the past that look up tables can quickly become competititve
with bit operators ( if your param is byte instead of int, a
256 entry table can tell you if the byte is a member of which classes). 
 

 we used a bitwise binary operator with the appropriate mask(s), there could

Re: [iText-questions] performance follow up

FYI I already use a table to map the char to the result for the delimiter 
testing and the speed improvement was zero in relation to plain comparisons.
