[iText-questions] Page resize with iText
Hi, I've am trying to resize pages so I can put header and footer. However, when I use PdfWriter and GetImportedPage and AddTemplate, I lose all annotations and interactive content. If I use PdfCopy I don't see a way to specify new page size (new Document(size) has no effect). So, my question is: Can you help me resolve this.

[iText-questions] PDFReader getPageContent() method returning weird escape codes
So I have a PDF that I read the contents. I didnt make this PDF but I I get
in the text the following two escape characters: \222 and \036
\222 seems to be the single quote (') and \036 seems to be something with
the letter (f)
These codes appear in several places however the Acrobat Reader displays it
correctly. Here is some partial examples.
*Example: 1
*... /Span /MCID 947 BDC /T1_1 1 Tf ( )Tj EMC /Span /MCID 948
BDC -13.716 -1.6 Td [(complex of)-14(fers eight scaled-down ball *
\036elds* replicated from famous )]TJ EMC /Span /MCID 949 BDC T*
..
*Example 2:*
.. /Span /MCID 950 BDC T* [(Y)110(ankee Stadium. And if *
you\222re* interested in *\036nding* ice in the middl\ ..
The above line is *Yankee Statium, And if you're interested in finding ice
in the middl*
I thought these are supposed to be Ascii Octal codes but they don't match
ASCII. Is there a different way of decoding them?
Here is the coee I use to read.
*PdfReader reader = new PdfReader(filein);
byte[] streamBytes = reader.getPageContent(1);
StringBuffer buf = new StringBuffer();
String contentStream = new String(streamBytes);
*
Any idea what this is? Do I need to post the whole PDF?
Thanks

If you want to use PdfWriter + PdfImportedPage, you need to copy all annotations separately, and scale all the dimensions. This isn't impossible, but it's plenty of work. I would advise against it. If you want to add a header and a footer, why don't you just change the MediaBox (and CropBox if any)? That way, you don't have to scale the content, you just provide more space. -- The ultimate all-in-one performance toolkit: Intel(R) Parallel Studio XE: Pinpoint memory and threading errors before they happen.

In your code snippet, I see: /T1_1 1 Tf
/T1_1 is a reference to a font dictionary. You can find the object
number of that font in the /Resources of the /Page dictionary.
If you look at the font dictionary, you'll find the encoding that is
needed, for example MacRomanEncoding, MacExpertEncoding, WinAnsiEncoding,...
Here is the code I use to read.
PdfReader reader = new PdfReader(filein);
byte[] streamBytes = reader.getPageContent(1);
StringBuffer buf = new StringBuffer();
String contentStream = new String(streamBytes);
Are you going to parse the PDF syntax yourself?
If so, how come you don't know about font dictionaries?
Did you try the com.itextpdf.text.pdf.parser classes?
If so, did they generate the correct output?

Re: [iText-questions] Question on inline image parse exception
Op 12/02/2011 1:39, Bharathi Kongara schreef: Hi guys, I'm fairly new to iText and have looked for options to get around the following error but couldn't find much help. All I'm trying to do is to just extract text from the first page of a PDF (a valid one). I tried to use both the PdfContentStreamProcessor.processContent method and the PdfTextExtractor./getTextFromPage /method but looks like the latter one is using the first one underneath anyway. Would appreciate any help! ExceptionConverter: _com.itextpdf.text.pdf.parser.InlineImageUtils$InlineImageParseException_: EI not found after end of image data Normally, images are added to a page using an external object: an Image XObject. This reduces the file size: the bytes of an image that is used on different pages are added to the file only once. In the case of inline images, the bytes are added in the content stream of a page. So if an image is added the content stream of two different pages, its bytes are in the PDF twice. You can recognize inline images in the content stream because they are between two operators: BI (= begin image) and EI (end image). The exception is telling you that it found a BI, but not an EI. There could be several reasons for this: parsing inline images is error prone. Maybe you aren't using the latest iText with the fixes to catch some of these errors. Maybe you've found a PDF revealing a bug in iText. You're not telling us which iText version you're using, nor are you providing us with the PDF, so we can't help you any further. -- The ultimate all-in-one performance toolkit: Intel(R) Parallel Studio XE: Pinpoint memory and threading errors before they happen.

Re: [iText-questions] suggestion about Paragraph and Phrase
Op 11/02/2011 18:05, Michael Niedermair schreef:
Hi Bruno,
I have a suggestion about Paragraph and Phrase.
It were nice, if a new Constructor exists, which set the init size of
the ArrayList.
This is a suggestion that should be posted to the mailing list.
Personally, I don't see the value of such an extra constructor. When I
use Phrase or Paragraph, there's absolutely no way to know the size of
the List in advance. If you have a controlled environment where you do,
you could extend the classes and use that specific subclass.
e.g.
public Paragraph(int initialCapacity) {
super(initialCapacity));
}
public Phrase(int initialCapacity) {
super(initialCapacity));
}
// change
public Phrase() {
this(16.0f);
}
The problem is, that the default init size is 10. Each time, I arrive
the limit, the size is increasing.
newCapacity = (oldCapacity * 3)/2 + 1
elementData = Arrays.copyOf(elementData, newCapacity);
10 .. copy array,
16 .. copy array
25 .. copy array
38 .. copy array
58 .. copy array
an so on.
If I add a lot of text (e.g. from a file, line by line) the arraylist
copy the array and copy the array and so on.
The init size set by the user can solve the problem with array copy.

Re: [iText-questions] Question on inline image parse exception
First, try out the very latest code from SVN and see if it fixes your problem. I added code a week ago to work around improperly implemented inline images in files generated by a large financial institution. If you still have problems after that, I'd suggest that you open a ticket and attach a *small* PDF that demonstrates the problem (i.e. a single page PDF). -- View this message in context: http://itext-general.2136553.n4.nabble.com/Question-on-inline-image-parse-exception-tp3302271p3302728.html Sent from the iText - General mailing list archive at Nabble.com. -- The ultimate all-in-one performance toolkit: Intel(R) Parallel Studio XE: Pinpoint memory and threading errors before they happen.

Re: [iText-questions] PDFReader getPageContent() method returning weird escape codes
I am planning to do something conceptually simple: Find the ? and ?
enclosing tags in a user designed pdf and replace it with input from a
database while maintaining kerning and tracking intact. Whatever is inside
? ? will be of a single font and single tracking.
Can this be done easily with the parser classes?
I ordered the book. I hope it has some good examples.
Your help is appreciated.

Considering that pdf essentially is a format that describes where individual or small groups of glyphs shall appear on screen or on paper, I don't consider that simple.
