Hi All,
Today i joined the itext mailing list so that i could contribute something.
I've written a basic indic ligaturizer for itextsharp (for indian character
support), much similar to what exists for Arabic. I've tested it with iText
source code, and it seems to work pretty well. The Indic ligaturizer is
very basic and simple, but it does solve a majority of issues with Hindi,
sanskrit and other devanagari characters. Also to note as there are several
languages (around 600, with 15 being the major ones) which are in use in
india, i haven't taken into account all those languages. For e.g. the
present code doesn't deal with telugu, kannada, tamil etc. (using the south
indian/dravidian characters). But does seem to work with hindi, sanskri,
nepali, marathi (all languages using the devanagari character set). Though
i've added support for gujarati too, but when i generated the PDF it was
empty, dont know why, but the visual studio debugger did show that the
characters were generated properly by the ligaturizer.
Due to limited time availability and also because i'am totally unfamiliar
with the iText code, as i hardly studied it, i just wrote a new file
IndicLigaturizer.cs with a class and several static methods (followed the
concept of ArabicLigaturizer.cs).
I am calling my IndicLigaturizer at this place, i don't know whether this
is the right place to do so, but i wanted a quick way to test my code,
hence the following.
Inside the PdfDocument.cs files
case Element.CHUNK: {
// if there isn't a current line available, we make one
if (line == null) {
CarriageReturn();
}
Chunk c = (Chunk) element;
StringBuilder s = new StringBuilder(c.ToString());
string p = IndicLigaturizer.FormatIndicString(s,
IndicLigaturizer.LANG_GUJR);
Chunk c1 = new Chunk(p, c.Font);
// we cast the element to a chunk
PdfChunk chunk = new PdfChunk(c1, anchorAction);
I tested the code by creating a sample csharp project and including the
newly generated itext dll.
Kindly let me know whether this could be of use to iText and could be added
there. If the moderators consider this worthy, we could develop it
further. Also let me know how, when and where i can post my code, so that
others can have a look at it and comment upon it.
Thanks
Ram
