Re: [iText-questions] Save PDF as plain text

[WMJ]

Hello,


Thanks for pointing out this.


Before that, I have once met with a PDF which has 1 mega bytes each compressed 
page stream. It did not take too long to parse them and convert it to the 
primitive command model.


If ET does not come after a BT, the DOM model might assume the rest commands 
are for the text object. If enclosing commands interleave each other, it is an 
error. The DOM model should not tolerate this, and the current event model 
can't cope with this either. We can't expect too much for the first design. At 
least, handling correct documents is the initial goal.


Yes, where the styles goes is a problem. It is good to discuss and find out a 
way to handle them.


I think it is useful to have a PDF command model. Just like XML DOM. XML DOM is 
not so efficient while encountering huge XML documents. But it is still a very 
popular tool for ordinary size documents. The real problem is not whether we 
should have one or not, but how to design the command model to make it useful 
and easy to use. Afterwards, we provide the two models and let developers 
choose their favorite one.


WMJ.

2.x.  Maybe it's setPDFAConformance.

However, as you know, 2.x is no longer supported.

Hi;

Is setConformance() in iText 5 only? We’re on iText 2 and I can’t find it 
anywhere. We do use iText to create the PDF so we should be ok on that part.

Thanks – dave

If you are creating the PDF ENTIRELY with iText – then you can just use the 
setConformance() API and it will take care of the details for you.  If you are 
starting with an existing PDF – then there aren't any options for iText at this 
time.

But that will ONLY get you PDF/A-1b.

PDF/A-1a requires that you properly structure & tag your content – something 
that iText will not (currently) do for you.  So you will need to do all that 
work yourself if you want full conformance.

And then there's PDF/A-2, which iText doesn't currently support either – but 
most folks aren't there just yet…

I didn’t know about pre-flight, that’s cool.

Ok, ran my iText generated document through it and got the following:

· Convert to PDF/A-1a (sRGB)

· Convert to PDF/A-1b (sRGB)

I then double clicked on “Verify compliance with PDF/A-1a” and got a lot:

· Author mismatch between Document Info and XMP Metadata

· CIDset in subset font missing (238 matches on 4 pages)

· Creation date mismatch between Document Info and XMP Metadata

· Device process color used but no PDF/A OutputIntent (253 matches on 4 
pages)

· Last Modification Date mismatch between Document Info and XMP Metadata

· MarkInfo missing

· Metadata missing (XMP)

· PDF/A entry missing

· Producer mismatch between Document Info and XMP Metadata

· Structured PDF: Structure tree root entry missing

The biggies seem to be the CIDset for the fonts and colors stored correctly. 
I’m guessing this is not a simple couple of hours to add in.

Is there a setting in iText to set these values or does this require a 3rd 
party app?

2. Even if you take the simplest PDF/A-1b there is lots of stuff to consider.

Careful with that phrase as it's led to misunderstanding by non-technical 
people.

What you really mean to say is "no externally referenced resources/assets".

1. That depends which PDF/A you mean:
PDF/A-1a or PDF/A-1b or PDF/A-2?

2. Even if you take the simplest PDF/A-1b there is lots of stuff to consider. 
Best you read the PDF/A spec. (ISO 19005-1:2005 or ISO 19005-2:2011) No 
javascript, no external referencing, colors etc etc.

3. What probably acrobat is looking at is the PDF/A tag in the meta 
information. Probably if you set that one acrobat will say its PDF/A. A better 
check is the PDF/A preflight check acrobat professional is offering. It shows 
you which part of the spec you are missing. If all tests pass then you probably 
have a 95% compliant PDF/A document.

If only it were that simple...

Embedded Fonts that meet the requirements (CIDSet, CharSet, Width matching,

Calibrated Colors including an OutputIntent

Limited Annots
And the list goes on

[iText-questions] appearance problem with Acrofields and Chinese

[mercoSygest]

Hi.
I'm using itextsharp 5.1.2 to fill with chinese text some acrofields.
These fields are set with "Arial unicode MS" font.

I set the 
 BaseFont.AddToResourceSearch(Parametri.AppPath & "iTextAsian.dll")
 BaseFont.AddToResourceSearch(Parametri.AppPath & "iTextAsianCmaps.dll")

FontArial = BaseFont.CreateFont("MSung-Light", "UniCNS-UCS2-H",
BaseFont.NOT_EMBEDDED)
...
_Dest.AcroFields.AddSubstitutionFont(FontArial)


All the fields have the correct values, but some of them are still "blank".
As you cas see here http://www.sygest.it/upgrade/itext/campi.pdf

the field named "DB_D6_XXX" is showing the value... but the field named
"#_ALBERO" not.

Only after a changes in the field object with acrobat, the value become
visible.

Usign preflight i can see that AP=>N=>Resources are different
the working one has the "Font" resources that is missing in the other field
.

Is this an itext issue ?

Thank you

Re: [iText-questions] Save PDF as plain text

[WMJ]

Hello,


Firstly I agree that it is easy to convert the current event model to DOM 
model. And I've done already implemented a very basic model with one or two 
days' work.


Currently I've processed quite some PDF files and I think huge page command 
trees are rare. Few PDF documents contain page contents more than 100KB per 
page. A DOM model is quite affordable. None to mention the fact that there are 
already quite a lot of PDF editor or processors out there. They do have their 
internal structure for those PDF objects to support content editing.


With the DOM model mentioned above, the developers who want to extract and 
analyze text can traverse the DOM tree and grab all PdfShowTextCommand objects. 
By inspecting PdfShowTextCommand object, they immediately know the font, size, 
position, color about those text pieces. A PDF rendering processor named MuPDF 
appears to have a similar API to extract texts.




And...



Although we all know that the PDF commands are linear. However, according to 
the PDF specification, there are de facto "multi-level" structures. For 
example, text commands must be placed within a pair of BT and ET command, and a 
pair of q and Q command encompasses graphic commands within a scope. In the DOM 
model, we don't need to worry about "whether I've added an ET command after the 
BT or not". A PdfTextAreaCommand denotes the BT and implies ET after all its 
sub-commands. Sub-commands of the PdfTextAreaCommand can be 
PdfTextMatrixCommmand, PdfShowTextCommand, PdfFontCommand, etc.




We might need listen to other people's opinions and requirements on PDF content 
processing.

A job that is easy to do doesn't mean that it is a nonsense. If integrating it 
into iText can save other programmers' days, doing such kind of low-tech jobs 
may be meaningful indeed.

I am currently experimenting on the PDF page command DOM model (I need support 
above the font encoding, font subsetting, and more, and more aspects that iText 
lacks). A good thing about the DOM model is that we don't have to create many 
small classes to consume the PDF command events.  A single class may do a 
variety of jobs against the same amount of content. I am trying to program an 
application to filtering out unwanted parts, or batch modifying parts in PDF 
pages. Event model is not so sufficient or effective when doing this. I may try 
to find out more and improve the design.

WMJ.

Just to be sure we are talking about the same thing. You initially posted
this as your code:

Is this really the current version of your code? I ask because it will not
compile properly as the local variables pdfDoc and writer are defined twice
in the same scope. Depending on your setup you might, therefore, in the
compiled classes still have a former version of that class in which you had
not yet added the iText code. This would easily explain why you don't get
any output there.
