Re: [iText-questions] Fonts supported by iText

2010-06-16 Thread Robert Franzese 
Well, we're creating a PDF that will be sent through a web service to a third 
party, and they (for some reason) have a limited number of fonts that they're 
willing to use.  I believe Arial is the most common one.

 Hello,
 
 I'm wondering if there's a place I can go to so I can find a list of fonts 
 supported by iText.

There are three different ways to answer this question.
These three different ways corresponds with three different tables
in chapter 11 of the 2nd edition of iText in Action:

Table 11.1: Font files and their extension

Type 1 Font files (.afm, .pfm, .pfb)
A Type 1 font is composed of two files: one containing the metrics (.afm 
or .pfm), and one containing the mathematical descriptions for each 
character (.pfb).

True Type Font files (.ttf)
A font based on a specification developed by Apple to compete with 
Adobe's Type 1 fonts.

Open Type Font files (.otf, .ttf, .ttc)
Cross-platform font file format based on Unicode. Open Type font files 
containing Type 1 outlines have an .otf extension. Filenames of Open 
Type fonts containing True Type data have a .ttf or .ttc extension. The 
.ttc extension is used for True Type Collections.

Answer 1: font files with these extensions are supported in iText.

Table 11.2: Subtype values for fonts

/Type1 A font that defines glyph shapes using Type 1 font technology.
/Type3 A font that defines glyphs with streams of PDF graphics operators.
/TrueType A font based on the True Type font format.
/Type0 A composite font?a font composed of glyphs from a descendant CIDFont.
/CIDFontType0 A CIDFont whose glyph descriptions are based on the 
Compact Font Format.

Answer 2: font files of the above subtypes (see ISO 32000 for the 
meaning of these subtypes) are supported in iText.

Table 11.3 lists the different font classes in iText that are at play,
and how they relate to each other.

Answer 3: read the book to find out how fonts work in iText.

  As a follow-up question, is there a way to be able to use additional fonts?

What additional type of fonts are you thinking about?
iText even allows you to create your own font (Type 3),
I guess I don't understand the question.

Subject: [iText-questions] Finding colorspaces used in a pdf

I want to make a program which analyzes a pdf to find which colorspaces are 
used in the document.
My program goes through every page in the pages tree and for every page I want 
to check the page's contenstream(s) for the operators
CS, SCN, G, RG and K (which are all used to set the current colorspace).

So, my question is, if I have an object of type 'PdfStream', is it possible to 
retrieve the CS, SCN, G, RG and K operators from the stream along with the 
operator parameters?

Hope my question is clear and that somebody can give me an answer :)

Thanks in advance for any help!!

Seems reasonable. That's not really a problem for iText.

 I believe Arial is the most common one.

Ask them if they can provide (licenses for) the fonts they allow.
Give them the option to provide an .otf, .ttf, .ttc or .afm+.pfb.
If they impose restrictions on particular fonts, they should have 
(licenses for) those font files.

Your counter-question will sound very reasonable.

If your mail contains confidential information, then why are you

As the posts to the mailing list are archived on different sites,
the whole world can read the confidential information.

Moreover: the people who support iText for free aren't interested
in confidential information (only paid customers can send us
confidential PDFs privately).

I for one, won't click on the link that was provided in the mail.

Therefore, I'll only answer the question in the subject-line.

Concatenating documents can be done in different ways depending
on the specific requirement.

Most of the times PdfCopy will do,
but in special cases PdfSmartCopy or PdfCopyFields are required.

[iText-questions] [off-topic] iText in California

2010-06-16 Thread Bruno Lowagie 
Hello,

a short personal message to iText developers in California: Next month, 
I'll probably visiting California with my wife and kids. I don't have an 
exact timing yet (end of July is the most accurate estimate for now).

Are there people, places, things I should visit?
It's probably best to answer this question off-list.

Please take into account that I'll have a busy schedule (business) and 
that I'll have two kids with me (almost 13 and almost 14).

If the trip is a success, I consider coming to the US more often, for 
instance to attend to conferences and to talk with developers (I'll have 
a book to promote soon).
best regards,
Bruno

[iText-questions] Image resize problem when migrating from 1.4.7 to 5.0.2

2010-06-16 Thread jan 

Hi,

I recently switched from 1.4.7 to 5.0.2 and noticed, that one image in a
table does not render correctly. I did some research and changed the code
to:

URL url = getClass().getResource(images/logo.gif);
logo = Image.getInstance(url);
Image logo;
cell = new PdfPCell(logo, false);

so that no fitting to the cell is performed. That did not work. I tried
scaleAbsolute to a defined size (the size of the image on disk):

logo.scaleAbsolute(48, 38);

but that did not change the size in the pdf. When I used a smaller size,
the image was rendered smaller. I tried some different values and at about
75% of the original size, the image in my new pdf had the same size as the
image in my old (correct) pdf. (Both pdf are scaled at 100%)

The cell is rendered correctly in size, the image overlays the text of the
next cell.

When I add the image directly to the document, I face the same problem.

I am migrating several projects that use reporting and adjusting every
image and finding its right scale value is impossible.

So why is the image resizing? What can I do to prevent that scaling?

Thanks for you help,

Jan

The parameter embedded is ignored in some cases.
For instance:
- the standard type 1 fonts such as Helvetica are never embedded,
- CJK fonts are never embedded,
- if encodiing Identity-H or -V is used, the font is always embedded,
no matter which value you pass for the embedded parameter.

 document.add(p);
 Thanks for your help.

If you want to embed Helvetica, you need to buy the .pfb file.
iText only ships with the (free) .afm file.

Or even better: search the web to find where you can buy a .ttf or .otf 
file containing the Helvetica font program.

(Note that we don't sell fonts, you'll have to use Google to find where 
you can buy Helvetica.)

 I’m using iTextSharp v4.1.2.
 
 I create a PDF which is a big listing in a table. My problem is that 
 some cells are really big (lots of line in it) and split over many 
 pages. I’m trying, when splitting occurs, to add a text at the top left 
 of the cell as a reminder.
 
  
 
 Problem is I don’t have any idea if it is possible ?

I'd use a Cell event to do this.
Add a boolean member variable to your implementation
of PdfPCellEvent, for instance cellIsAdded = false;
Check this variable in the layout() method.
If it's false, set it to true;
if it's truee, add the reminder.

Re: [iText-questions] NPE while Extracting text

2010-06-16 Thread Kevin Day 

I will add to Mark's (excellent) stream of consciousness analysis:

The next step is to see what the name of the font resource is that is
causing the problem.  Then, load RUPS and dig into the page dictionary and
find the entry for that font resource - given what Mark is showing in the
source, most likely the font resource isn't defined.

There's always a question with this sort of thing about 'why does Acrobat
show the file OK' - the answer is that Acrobat is very permissive - there
are all sorts of problems like this that it may silently ignore.  Older
versions of Acrobat often show problems that newer versions ignore.

And then, of course, there's always the possibility that there's a problem
with iText, and the strategy for looking up font resources isn't quite in
sync with the PDF spec.  I don't *think* that is the case here, but it's
always possible.

If you do wind up providing the PDF so we can take a look, be sure to also
provide font file that think may be involved.

[iText-questions] External Dependencies

I would like to know if any of the iText versions needs native libraries or if 
it's 100% pure.
As far as my limited Java knowledge allowed me to read and understand the

Sorry for bothering the list, but I am a bit pressed for time.

[iText-questions] Compare font size with Word

Re: [iText-questions] Compare font size with Word

2010-06-16 Thread Mark Storer 
There's a really simple solution here.  Render your word document as a
PDF and use PdfStamper to Add Stuff.

 

To address your question directly, lets first ass-u-me that you're using
100% zoom.

 

1) In PDF, we always use 72 DPI (dots per inch).

2) In windows, you can have a variety of DPIs, though 96 seems pretty
standard.

 

As such, I'd expect a point difference of 25% to match (15 point, not
13).  So this might not be the issue at all.

Re: [iText-questions] Spam: Spam: External Dependencies

2010-06-16 Thread Mark Storer 
iText is pure java, yes.

However, it relies on some other .jar files... from bouncy castle,
which I thought were included in the distribution.  

There are also a couple different itext*.jar files you might be missing.
Asian fonts take up lots of space and aren't part of the main
distribution.  I believe there's some hyphenation logic that is also
separate.

iTextAsian.jar  iTextAsianCmaps.jar.  Is the hyphenation stuff still
its own jar?

 Subject: Spam: Spam: [iText-questions] External Dependencies
 
 Hello list!
 
 I would like to know if any of the iText versions needs native
libraries
 or if it's 100% pure.
 As far as my limited Java knowledge allowed me to read and understand
the
 sources,  I would assume there aren't any external dependencies, but I
 need to make sure.
 
 Sorry for bothering the list, but I am a bit pressed for time.
 
 Thanks in advance,
 
 Markus

Re: [iText-questions] NPE while Extracting text

2010-06-16 Thread Ben Short 
On Mark's advice I downloaded the source code from the 5.0.2 branch
and dug a little deeper...

The NPE is thrown on the following line of the DocumentFont constructor.

fontName = PdfName.decodeName(font.getAsName(PdfName.BASEFONT).toString());

It turns out that font.getAsName(PdfName.BASEFONT) returns null.

font, which is a PdfDictionary, has the following values in its hash map...

{/FontBBox=[-2, -9, 38, 40], /LastChar=121, /FontMatrix=[0.24, 0,
0, 0.24, 0, 0], /Type=/Font, /Resources=Dictionary, /CharProcs=134
0 R, /Encoding=72 0 R, /Subtype=/Type3, /Name=/C0HN2000T1X005000,
/Widths=135 0 R, /FirstChar=32}

You'll notice that there is no key for /BaseFont.

I'm not sure I can post the whole pdf to a public news group... I will
see if I can cut it down to a page or so of none sensitive data first.

 I will add to Mark's (excellent) stream of consciousness analysis:

 The next step is to see what the name of the font resource is that is
 causing the problem.  Then, load RUPS and dig into the page dictionary and
 find the entry for that font resource - given what Mark is showing in the
 source, most likely the font resource isn't defined.

 There's always a question with this sort of thing about 'why does Acrobat
 show the file OK' - the answer is that Acrobat is very permissive - there
 are all sorts of problems like this that it may silently ignore.  Older
 versions of Acrobat often show problems that newer versions ignore.

 And then, of course, there's always the possibility that there's a problem
 with iText, and the strategy for looking up font resources isn't quite in
 sync with the PDF spec.  I don't *think* that is the case here, but it's
 always possible.

 If you do wind up providing the PDF so we can take a look, be sure to also
 provide font file that think may be involved.

Re: [iText-questions] NPE while Extracting text

2010-06-16 Thread Mark Storer 
According to the PDF Reference (ISO 32000), BaseFont is a required
field.  So where did this PDF come from?

It's possible that the font's FondeDescriptor has a /FontName entry
(also required, and required to match BaseName).  I suspect Adobe has
bullet-proofed their applications to the point where either will
suffice.  Heck, they could even query the font program directly if it
was available.

So while I wouldn't go so far as to call it a bug in iText, we certainly
could be more durable in the face of malformed PDFs.  At the very least,
we could throw something more meaningful than an NPE.

Ben?  Do you have Acrobat 9 Pro?  It has a PDF syntax check that would
(hopefully) help you reach this sort of conclusion much faster, and
wouldn't require you to fold/spindle/mutilate your PDF for public
consumption.

Re: [iText-questions] NPE while Extracting text

2010-06-16 Thread Kevin Day 

ok - I ran into this issue myself a month or so ago.  It's been fixed in the
5.0.3 codebase (which is the current HEAD in SVN).

/** Creates a new instance of DocumentFont */
DocumentFont(PRIndirectReference refFont) {
encoding = ;
fontSpecific = false;
this.refFont = refFont;
fontType = FONT_TYPE_DOCUMENT;
font = (PdfDictionary)PdfReader.getPdfObject(refFont);
PdfName baseFont = font.getAsName(PdfName.BASEFONT);
fontName = baseFont != null ?
PdfName.decodeName(baseFont.toString()) : Unspecified Font Name; // *
this is the line with the fix
PdfName subType = font.getAsName(PdfName.SUBTYPE);

the bolded text above is the fix.

Re: [iText-questions] NPE while Extracting text

2010-06-16 Thread Kevin Day 

Mark - FYI, basefont isn't required for Type3 fonts (or TrueType for that
matter).  I had the same reaction when I first ran into this issue, but the
spec never lies, right?  It just injects ambiguity and confusion.
