Two obvious counter-questions:
Were the fonts embedded?
What are the scaling settings in the print dialog?

in iText PDF

 

Images are not rotated around their center. The coordinate of the rotation
pivot is (0, 0). If you rotate something, you have to watch out that it is
not rotated 'off' your page. you may have to perform a translation to keep
the object on the page.

Re: [iText-questions] Varied Results

2010-02-23 Thread Jonathan Logue

Has anyone had a situation where the output when printing an iText generated 
PDF from one computer had a different result than another computer. Before I 
even get into the specifics of the implementation, I am just curious if this is 
even possible. Could instructions be interpreted differently by different 
Reader instances? In our situation, text appears 1/4 of an inch, or so, off.

Thanks!

Re: [iText-questions] Using Images extracted from a pdf

Text extraction is difficult too - it just so happens that someone has written 
the code already and contributed it back, so that you can take advantage of it. 
 Before then, it was quite a nightmare.

Now you have a requirement (for your job, I assume) and the code doesn't exist 
so you need to write it.  If you are unable to do so, due to lack of knowledge, 
time, etc. then perhaps your company should consider hiring iText Software to 
write it for you.  I am sure they would be glad to it - and in less time than 
you've already spent.

The alternative - and there isn't any shortcut - is for you to learn about PDF 
and image formats...

Re: [iText-questions] Re tain DuplexMode property


I've narrowed down the issue a little more. When I remove the following lines
of code, the duplexMode is retained.

pdfStamper.addViewerPreference(PdfName.HIDETOOLBAR, pdfBoolean);
pdfStamper.addViewerPreference(PdfName.FITWINDOW, pdfBoolean);

It seems adding additional viewer preferences overwrites the original
preferences.

I am not attaching the before and after pdf's. The after pdf has
confidential information. If you really want to look at both, let me know
and I will strip the confidential info out.

Re: [iText-questions] Using Images extracted from a pdf

The image is decompressed and then "injected" into the PDF.  Same with EVERY 
TYPE of image EXCEPT JPEG.

what exactly happens with this?

say that it is in PNG it is decompressed to be "injected" into PDF?

or she keeps your PNG format, but the bytes are encoded with the FlateEncode

a matter of finding the filter and decode do I get it.

and if the image is uncompressed before being inserted to PDF, how do I know

Re: [iText-questions] Using Images extracted from a pdf

Bits per pixel is the BitsPerComponent value in the image object

Pixels per line (POR LINHA) is _NOT_ Width * bits.  It's Width * NumComponents, 
where NumComponents is based on the colorspace in question (eg. RGB == 3, CMYK 
== 4).

I must doing something wrong, because the following doesn't work

pdfReader is the pdf I'm reading in

[iText-questions] Page is rotated after being scaled

2010-02-23 Thread Valentin Avksentyev

I'm using the following code to scale PDF pages down to 8.5x11, however, for 
some PDFs the page ends up being rotated 90 degrees after being scaled.  One 
more detail, PDFs that are rotated seem to be created by scanners.

Here is part of the relevant part of the code that I use:

PdfContentByte cb = writer.getDirectContent();
PdfImportedPage page = writer.getImportedPage(reader, i);
com.lowagie.text.Image image = com.lowagie.text.Image.getInstance(page);
Rectangle psize = reader.getPageSize(i);
float area = psize.getHeight() * psize.getWidth();
float areaDiffPercent = (letterArea / area) * 100;
image.setAbsolutePosition(10, 20);
cb.addImage(image)image.scalePercent(areaDiffPercent);

Any help is appreciated

Best,
-Val

HeaderFooter was REMOVED in 5.0.0 and 5.0.1.
Therefore it's impossible that you can compile without errors.

Er... I didn't understand the initial question,

[iText-questions] HashMap for FactoryProperties

2010-02-23 Thread privat

Hello,

Since I updated my lib to 2.1.7.
Because createParagraph from HashMap is nolonger supported.
I have trouble with that:

public static Paragraph createParagraph(HashMap props) {
Paragraph p = FactoryProperties.createParagraph(props);

setParagraphFirstLineIndent(p, (String)props.get("indent"));

return p;

}

What should I do to fix that in a easy way?
Maybe a stupid question, but I don't know this part very well.

Thanks for your help

br

Markus

handle the image ..
put on it still can not do the same here, get all the images from a PDF -.-

and I would not like to mix several jars.

you have any examples of how to get the images using pdf renderer or pdfbox

 OK, we're talking about a PNG.
 If you've read chapter 10 of the 2nd edition of "iText in Action",
 you know that PNGs are transformed into zipped pixels.
 If you didn't know, you should read the book!

 Of course, why do you think that would work???

 Of course, you're sending iText a bunch of pixels,
 but: what are the dimensions of the image,
 how many bits are there per component?

Re: [iText-questions] PDF size after oPdfStamper.FreeTextFlattening, FormFlattening needs to go on a diet ??

2010-02-23 Thread tim clark

Just for the Archives I have found a solution to this file size issue but I 
think it is
application specific but this use case may fit someone else
The pages that we are concatenating are identical in layout, font etc
only the content changes  so I instead of using .text.pdf.PdfCopy
we tried iTextSharp.text.pdf.PdfSmartCopy this results in size saving
that are in fact better than Adobe Acrobat Optimized
the test file that was once 341K is now 131K
and x Object Forms is now only 52K compared to the optimizer at 78K

Re: [iText-questions] After rotation, images are getting displced in iText PDF

2010-02-23 Thread Klas Lindbäck

Images are not rotated around their center. The coordinate of the 
rotation pivot is (0, 0). If you rotate something, you have to watch out 
that it is not rotated 'off' your page. you may have to perform a 
translation to keep the object on the page.

[iText-questions] Best practice for concatenation

Hi,

I have a working piece of code that does the following:

1. Read a PDF and fill out the form fields.
2. Create a new document from scratch
3. Read a fix PDF
4. Concatenate the 3 pages and save to file.

I don't want to save anything to file but the resulting PDF.
I'd like to know if there a any big mistakes. What could be done 
in a better way.

Thanx and greetings

probably the open source pdf renderer would answer your questions and provide
more context. I seem to recall it was pretty easy to modify to extract page 
images
in your favorite format, probably in process of rendering the included images
are extracted etc.

Re: [iText-questions] Rotation from center point of any object

2010-02-23 Thread Paulo Soares

Image.RotationDegree=45 will rotate the image from the center point but it will 
place it by the bottom left corner of the rectangle containing the image after 
the rotation. If you have problems calculating the position after that you 
should go back to kindergarden and learn how to do sums. Did you by any chance 
read the book or looked at the examples or did any effort to solve the problem 
rather than asking the same question 10 times? (and don't tell me the examples 
are in Java)

If this is that urgent,
can't you just "kluge" a solution by translating the output or is this more
involved than a one-line call? I thought the conclusion was something
to that effect being the best itext solution.
Designing an API is always a tradeoff, and it is possible there is no
"center" parameter
anywhere

[iText-questions] Rotation from center point of any object

2010-02-23 Thread rhul_rk


Hi Everyone!!!

Just want to know, is there any mechanism in iTextSharp to rotate the object
from center point of object, instead of Bottom left Corner. iTextSharp has a
rotation mechanism which is "Image.RotationDegree=45". But it is not
allowing us to rotate the object from center point. It allowing us to rotate
the image from Bottom Left Corner. Our requirement is to rotate the object
from center point of object.

Can any one help us???

Looking towards your great support...

Regards,
Rahul

I guess I'd just ask how hard it would have been for original author to
include enough information, either with standard or an agreed upon
private convention, to the OP to do any required re-layout? That is, 
what would be involved in creating the original pdf with enough logical
structure to make it likely you could accomodate a font change ( or
just extract the words that are often the only thing people care about,
not fonts and columns etc)?

This is just a variant of my recurring rant ( we want information not
pictures in many cases to feed other computer programs ) to which you 
contribute a good
point- fonts are complicated and human readability ads a lot of stuff. 
A human audience of course is perfectly valid and there is nothing wrong with
using graphics to make it easier for the reader. However, having a short 
tractable alphabet, rather than
say words composed of unordered and unbounded collection of things,
or even 24-bit color pictures,  is
a big asset in organizing information- once you start adding stuff it can
be confusing unless you take some care to separate the information from artwork.

That may be your only option for the time being.
We're hoping to finalize the parser functionality in 3 to 6 months.
Until then, the API is likely to undergo some changes.
It's all very new.

Use ColumnText.
This object allows you to add high-level objects at absolute positions.
There are lots of examples in the MEAP version of "iText in Action 2nd 
edition".

If you use PdfCopy and set the color profile at the end it will work.

Hi,

I know how to generate PDF/A with iText. What if I want to use one page
of PDF/A doc X and one page of PFD/A doc Y and append them. Will the new
PDF/A still be PDF/A? What about the embedded fonts,...?

That's for you to find out. I don't know.
You'll have to take a look at the parser package.

It is possible to get all elements (with position and bounding box) of 
the page? So i can calculate it self.

Do you mean you want to know which part of the margin is blank? That's 
very difficult. I didn't have the time to try the new PDF parsing 
functionality yet. I don't know if it's possible yet with iText.

Oops, I had some code in my ClipBoard, but instead of pasting it,
I hit the send button. Here's what I intended to paste:

public void manipulatePdf(String src, String dest)
 throws IOException, DocumentException {
   PdfReader reader = new PdfReader(src);
   int n = reader.getNumberOfPages();
   PdfDictionary pageDict;
   PdfRectangle rect = new PdfRectangle(55, 76, 560, 816);
   for (int i = 1; i <= n; i++) {
 pageDict = reader.getPageN(i);
 pageDict.put(PdfName.CROPBOX, rect);
   }
   PdfStamper stamper
 = new PdfStamper(reader, new FileOutputStream(dest));
   stamper.close();
}

Yes, loop over the page dictionaries (PdfReader.getPageN())
and add a crop box to these dictionaries.

Re: [iText-questions] Retrieve Fonts from an existing PDF?

Nirmal Fernando wrote:

This isn't necessarily impossible, but in most cases it's very difficult 
and in some cases it's very unwise.

For instance: what if only a subset of the font is present in the PDF? 
Then you'll never be able to retrieve the full font, and will you 
replace this subset with a full font or a corresponding subset?

Do you know anything about encoding? Do you know anything about CMaps? 
Do you know anything about the differences in metrics?

For instance: the width of the words "Foobar Film Festival" is 178.74 pt 
in Helvetica, but only 157.90 in Times-Roman for the same font size 
(12). In other words: if you replace Helvetica with Times-Roman, you'll 
screw up your entire layout. Remember that PDF is NOT a Word processing 
format; every glyph is positioned at a predictable location. If you want 
to change the font, you need to do the layout all over again. That is: 
recreate the PDF from scratch.
