I'm trying to create a content page with lines like:
Chapter one...................101
Chapter two...................102
etc.
Some chapters are in English some are in Arabic. But the page numbers should
always be on one side (left or right).
I have this code:
/FontFactory.RegisterDirectory(Environment.GetFolderPath(Environment.SpecialFolder.Fonts));
iTextSharp.text.Font font = FontFactory.GetFont("Tahoma",
BaseFont.IDENTITY_H, 15f, iTextSharp.text.Font.NORMAL, new BaseColor(0, 0,
0));
using (Document doc = new Document(PageSize.A4))
{
PdfWriter writer = PdfWriter.GetInstance(doc, new
FileStream("C:\\sample.pdf", FileMode.Create));
doc.Open();
doc.SetMargins(52f, 52f, 52f, 52f);
PdfContentByte content = writer.DirectContent;
content.SaveState();
content.Rectangle(doc.Left, 0, doc.Right - doc.Left,
doc.Top);
content.SetColorFill(new BaseColor(240, 240, 240));
content.Fill();
content.RestoreState();
ColumnText colt = new ColumnText(content);
colt.SetSimpleColumn(doc.Left, doc.Bottom, doc.Right,
doc.Top);
ColumnText coltrtl = new ColumnText(content);
coltrtl.SetSimpleColumn(doc.Left, doc.Bottom, doc.Right,
doc.Top);
coltrtl.RunDirection = *PdfWriter.RUN_DIRECTION_RTL*;
Paragraph par = new Paragraph("مكتبة مؤلفة من 15 دورة
تفاعلية", font);
par.Alignment = *Element.ALIGN_LEFT*;
coltrtl.AddElement(par);
coltrtl.Go();
doc.Close();
}/
As you can see, the /Element.ALIGN_LEFT/ for RTL ColumnText means aligning
to the right:
<http://itext-general.2136553.n4.nabble.com/file/n4660411/02.png>
Now let's add a separator:
/Paragraph par = new Paragraph("مكتبة مؤلفة من 15 دورة
تفاعلية", font);
par.Alignment = Element.ALIGN_LEFT;
*iTextSharp.text.pdf.draw.DottedLineSeparator separator =
new iTextSharp.text.pdf.draw.DottedLineSeparator();
par.Add(new Chunk(separator));
par.Add(new Chunk("123", font));
* coltrtl.AddElement(par);
coltrtl.Go();/
We get:
<http://itext-general.2136553.n4.nabble.com/file/n4660411/03.png>
When the separator is added we have to align the paragraph to the right:
/Paragraph par = new Paragraph("مكتبة مؤلفة من 15 دورة
تفاعلية", font);
par.Alignment = *Element.ALIGN_RIGHT*;
iTextSharp.text.pdf.draw.DottedLineSeparator separator = new
iTextSharp.text.pdf.draw.DottedLineSeparator();
par.Add(new Chunk(separator));
par.Add(new Chunk("123", font));
coltrtl.AddElement(par);
coltrtl.Go();/
<http://itext-general.2136553.n4.nabble.com/file/n4660411/04.png>
This looks good. But some Arabic text may contain English words:
/Paragraph par = new Paragraph("*MS Office 2013 - الترقية من
MS Office 2010*", font);
par.Alignment = Element.ALIGN_RIGHT;
iTextSharp.text.pdf.draw.DottedLineSeparator separator = new
iTextSharp.text.pdf.draw.DottedLineSeparator();
par.Add(new Chunk(separator));
par.Add(new Chunk("123", font));
coltrtl.AddElement(par);
coltrtl.Go();/
<http://itext-general.2136553.n4.nabble.com/file/n4660411/05.png>
To fix this we have to add the RightToLeft mark at the end of the string:
/Paragraph par = new Paragraph("MS Office 2013 - الترقية من
MS Office 2010" *+ ((char)0x200F)*, font);
par.Alignment = Element.ALIGN_RIGHT;
iTextSharp.text.pdf.draw.DottedLineSeparator separator = new
iTextSharp.text.pdf.draw.DottedLineSeparator();
par.Add(new Chunk(separator));
par.Add(new Chunk("123", font));
coltrtl.AddElement(par);
coltrtl.Go();/
<http://itext-general.2136553.n4.nabble.com/file/n4660411/06.png>
This looks good. Now we have to solve a situation for multi-line chapter
names:
Paragraph par = new Paragraph("*تفاعليةتفاعليةتفاعلية
تفاعليةتفاعليةتفاعلية تفاعليةتفاعليةتفاعلية تفاعليةتفاعليةتفاعلية*" +
((char)0x200F), font);
par.Alignment = Element.ALIGN_RIGHT;
iTextSharp.text.pdf.draw.DottedLineSeparator separator = new
iTextSharp.text.pdf.draw.DottedLineSeparator();
par.Add(new Chunk(separator));
par.Add(new Chunk("123", font));
coltrtl.AddElement(par);
coltrtl.Go();
<http://itext-general.2136553.n4.nabble.com/file/n4660411/07.png>
And we have a problem. The first line should be aligned to the right. But as
we know, we cannot use Element.ALIGN_LEFT:
Paragraph par = new Paragraph("تفاعليةتفاعليةتفاعلية
تفاعليةتفاعليةتفاعلية تفاعليةتفاعليةتفاعلية تفاعليةتفاعليةتفاعلية" +
((char)0x200F), font);
par.Alignment = *Element.ALIGN_LEFT*;
iTextSharp.text.pdf.draw.DottedLineSeparator separator = new
iTextSharp.text.pdf.draw.DottedLineSeparator();
par.Add(new Chunk(separator));
par.Add(new Chunk("123", font));
coltrtl.AddElement(par);
coltrtl.Go();
<http://itext-general.2136553.n4.nabble.com/file/n4660411/08.png>
Can this be solved?
Sometimes, we need to keep the page numbers on the right side even for
Arabic texts. I see only one solution: Add the page number first then the
chapter title:
/Paragraph par = *new Paragraph("123", font);*
par.Alignment = Element.ALIGN_RIGHT;
iTextSharp.text.pdf.draw.DottedLineSeparator separator = new
iTextSharp.text.pdf.draw.DottedLineSeparator();
par.Add(new Chunk(separator));
*par.Add(new Chunk("مكتبة مؤلفة من 15 دورة تفاعلية" +
((char)0x200F), font));
* coltrtl.AddElement(par);
coltrtl.Go();/
<http://itext-general.2136553.n4.nabble.com/file/n4660411/09.png>
This works but only for single-line chapters:
/Paragraph par = new Paragraph("123", font);
par.Alignment = Element.ALIGN_RIGHT;
iTextSharp.text.pdf.draw.DottedLineSeparator separator = new
iTextSharp.text.pdf.draw.DottedLineSeparator();
par.Add(new Chunk(separator));
par.Add(new Chunk(*"تفاعليةتفاعليةتفاعلية
تفاعليةتفاعليةتفاعلية تفاعليةتفاعليةتفاعلية تفاعليةتفاعليةتفاعلية"* +
((char)0x200F), font));
coltrtl.AddElement(par);
coltrtl.Go();/
<http://itext-general.2136553.n4.nabble.com/file/n4660411/10.png>
Can this be solved?
Similar problem is with English text. I'm unable to draw a multi-line
chapter name and a page number on the left side:
/Paragraph par = new Paragraph(*"This is a chapter with a
really really really really really really really long name"*, font);
par.Alignment = Element.ALIGN_RIGHT;
iTextSharp.text.pdf.draw.DottedLineSeparator separator = new
iTextSharp.text.pdf.draw.DottedLineSeparator();
*separator.Alignment = Element.ALIGN_RIGHT;
* par.Add(new Chunk(separator));
par.Add(new Chunk("123", font));
coltrtl.AddElement(par);
coltrtl.Go();/
<http://itext-general.2136553.n4.nabble.com/file/n4660411/11.png>
The /separator.Alignment /has no effect. We can use the same trick with the
RightToLeft mark:
/Paragraph par = new Paragraph("This is a chapter with a
really really really really really really really long name" +
*((char)0x200F*), font);
par.Alignment = Element.ALIGN_RIGHT;
iTextSharp.text.pdf.draw.DottedLineSeparator separator = new
iTextSharp.text.pdf.draw.DottedLineSeparator();
separator.Alignment = Element.ALIGN_RIGHT;
par.Add(new Chunk(separator));
par.Add(new Chunk("123", font));
coltrtl.AddElement(par);
coltrtl.Go();/
<http://itext-general.2136553.n4.nabble.com/file/n4660411/12.png>
But we have the same problem - the first line should be aligned to the
right.
