Auto-leading with irregular columns has to be done with approximations and I

 Great and being able to set word spacing would be a nice thing as well.
 Oh
 yeah and while we're adding to your workload, Paulo ;-j do you have any
 plans to fix the leading issues that occur when using non-rectangular
 columns?

 Normally when two fonts appear on the same line or with an image the
 leading
 should come from the largest item on the line (via multipliedLeading).
 This
 works fine for simple i.e. rectangular columns but not with
 non-rectangular columns which instead assume a fixed leading for all
 lines.

 Looking at the code I can see that this is not going to be a completely
 trivial problem to fix however because calculating the length of the
 line is
 then dependent on finding the intersection with the column outline at
 the
 height of the line. A solution would need to calculate both the line
 length
 and line height simultaneously and deal with cases like where columns
 that
 get narrower as they go down the page (i.e. the line nees to get shorter
 as
 the line gets higher).

Re: [iText-questions] Tables (both types) with PdfTemplate-based images

Subject: [iText-questions] Tables (both types) with PdfTemplate-based images


 I have been doing some testing, and have found some problems regarding
 PdfTemplate-based image support -- specifically within tables.

 1.  When I create a Table object with new Table(1), and add 5 cells to
 it, the application crashes due to an ArrayIndexOutOfBoundsException
 while the table converts itself to a PDFContentByte.  I am fairly
 certain this is due to the fact that the table crashes when it tries to
 span the page, since 4 such cells will fit on the page.  Each Cell has
 one element - a PdfTemplate containing the pixels from the Canvas
 subclass attached to this message.

 2.  When only 4 such cells are used, they display OK in Acrobat Reader 5
 using Win2000.  However, when one goes to print the PDF, the first three
 cells appear on the page correctly, with the fourth one at a seemingly
 random location.  Frequently it overlaps one of the first three and is
 smaller than the first three (although all cells are created in the same
 fashion).  With more complex documents, the PdfTemplate-based images
 tend to stack on top of each other when printed (and sometimes when
 scrolling in Acrobat).

 This wrong rendering occurs independent of the printer I use -
 PostScript or not (I have tried both with a HP Color LaserJet 4550N that
 supports PS level 3 as well as HP's PCL 6).

 3. Problem #2 occurs with PdfPTable as well.  PdfPTable drops cells it
 can't fit onto a page and so does not have the first exception.

 What's really interesting about this is that Raw images created using
 java.awt.BufferedImage do not have this problem, but instead are
 sometimes scaled down and then lose detail or such, so PdfTemplate
 really si the best solution if the PdfContentByte generation and
 positioning problems can be fixed.

 The other strange thing about this is that the problem usually happens
 when the table w/ images is on the second or subsequent pages of the
 document.

[iText-questions] tagmap problem

2002-08-13 Thread pooja sharma
It is very difficult to write a tagmap for any kind of xml. The files given in the tutorial as examples are all xml files (for which the tagmaps are written) and there is no need to apply any xsl on them. In my project, xml and xsl -two separate files are provided in order to convert them to PDF. I don't know each and every kind of iText tag that can be used for writing tagmaps. 
And if I convert a large xml and xsl into text file and then to PDF, then I get "out of memory" error . Is it because a tree structure is formed in the memory as in case of FOP? 
In the the Java code in which I am  converting text into PDF, Iam reading the text file into a string and then using the "paragraph.add" function. To remove the "out of memory" problem, I have used "System.gc()" function butit has made the processing very slow - a 3MB filewill take hours 
What should I do to reduce the processing speed?
What should I do so that meta-info is not lost?
If I have to write tagmaps, How should I write them for any xml and xsl?

Quoting pooja sharma [EMAIL PROTECTED]:

 
 It is very difficult to write a tagmap for any kind of xml. The files given
 in the tutorial as examples are all xml files (for which the tagmaps are
 written) and there is no need to apply any xsl on them. In my project, xml
 and xsl -two separate files are provided in order to convert them to PDF. I
 don't know each and every kind of iText tag that can be used for writing
 tagmaps. 

I don't know every kind of iText either (allthough I wrote the code;
I just don't remember them). Fortunately, all classes have very easy
names. If I need a paragraph, I read the constructor of class Paragraph
that takes a Properties object. If I need a chapter, I do the same with
class Chapter, and so on...

How difficult can that be???

 And if I convert a large xml and xsl into text file and then to PDF, then I
 get out of memory error . Is it because a tree structure is formed in the
 memory as in case of FOP? 

It's because it is a bad idea to stuff a 3MB String into a Paragraph
object.

 In the the Java code in which I am  converting text into PDF, Iam reading the
 text file into a string and then using the paragraph.add function. To
 remove the out of memory problem, I have used System.gc() function but it
 has made the processing very slow - a 3MB file will take hours  

And where do you perform the garbage collect?
I don't understand why this would help you avoiding the OutOfMemory.
Allthough I still think it's a bad idea to degrade your XML
to text, you could split your textfile with '\n' as delimiter.

In Pseudocode it would look like this:
Paragraph p;
StringTokenizer st = new StringTokenizer(myText, \n);
while (st.hasMoreTokens()) {
p = new Paragraph(st.nextToken());
doc.add(p);
}

 What should I do to reduce the processing speed?

I think you mean INCREASE processing speed.

 What should I do so that  meta-info is not lost?

Tagmaps are REALLY EASY. Use them.
(Remark: in some situations in which the same tagname has
different meanings depending on the context, tagmaps will
not be sufficient.)

 If I have to write tagmaps, How should I write them for any xml and xsl? 

Get rid of the xsl.

 PLEASE GUIDE

As I stated earlier: free software developers can't do the work
YOU are paid for. But if you send a small sample of your XML
(in which no more than 5 different tags are used), I can get you
started by writing you a demo tagmap.

For obvious security reasons you cannot perform this configuration

2002-08-13 Thread Paulo Soares

ColumnText does proper tracking and spacing according to the set rules. If
you make PdfDocument.ratio=1000f tracking is eliminated and all that
remains is word spacing. It's possible to change the width of the space
character in BaseFont.getWidths(). Maybe that would be enough for you.

 Auto-leading with irregular columns has to be done with approximations
 and I
 don't know if the new ColumnText model will allow it. We'll see.

 Subject: [iText-questions] ColumnText issues (was Re: leading, tracking,
 kerning)


   Great and being able to set word spacing would be a nice thing as
 well.
   Oh
   yeah and while we're adding to your workload, Paulo ;-j do you have
 any
   plans to fix the leading issues that occur when using non-rectangular
   columns?
  
   Normally when two fonts appear on the same line or with an image the
   leading
   should come from the largest item on the line (via
 multipliedLeading).
   This
   works fine for simple i.e. rectangular columns but not with
   non-rectangular columns which instead assume a fixed leading for all
   lines.
  
   Looking at the code I can see that this is not going to be a
 completely
   trivial problem to fix however because calculating the length of the
   line is
   then dependent on finding the intersection with the column outline at
   the
   height of the line. A solution would need to calculate both the line
   length
   and line height simultaneously and deal with cases like where columns
   that
   get narrower as they go down the page (i.e. the line nees to get
 shorter
   as
   the line gets higher).

   : Thank you. That's what I'm doing now (and must not do for
 script-like
   : fonts).

I would recommend fixing the typo in the line below.  It should be 
application/pdf (note the double 'p').  That should help a lot.  :)
