[Indic-computing-users] Help needed for modifying Akruti Devnagari font.

[Shashank A. <sha...@hb...>]

Hi,

We are working on linux localisation in HBCSE under guidance of Mr.
Nagarjuna. We hv been able to partially transform the font to unicode
mapping. Although we could not figure out where to place the glyphs
required for jodaksharas as no positions are specified for them. 

We are using pfaedit for modifying the font can we use the blank
positions ( marked with a black sqare and a '?' sign embeded in it )
for these extra glyphs.

You need to have all the characters required as per Unicode 
chart for that specific language. Beyond that, you can have 
any number of glyphs without any Unicode value assigned to 
them. Put all the glyphs in any order. Import it to VOLT and 
then give them names using the glyph editor. Make glyph 
groups like full, half, vowels, matras, etc. Add the 
language, feature, lookups, etc. You can use Mangal.Volt.TTF 
which comes along with VOLT as reference.

The Unicode standard only defines the base characters and for
yuktakshars you need to add open type tables (ie, convert the fonts into
OTF)
for OTF creation, you would need M$ Volt (does any Free alternative
exist??)
At the very basic level, the Open Type tables let you specify a
particular series of of characters, for which a single glyph is
displayed - and in this way you can display yuktakshars. eg.

k+halant+k -> kk

This is a very basic level thingy, and you can refer to the Microsoft 
OTF specs at 
http://www.microsoft.com/typography/specs/default.htm
And for Devanagari fonts, take a look at
http://www.microsoft.com/typography/developers/volt/devanagari.htm

PfaEdit cant do all tables. Malayalam OTF was built using PfaEdit alone.
In Malayalam the first req was to substitute a unicode stream with a 
single glyph. For this please see the Ligature field in Char Info menu.
(Try Ctrl+i in selecting a glyph)

In the ligature field you have to give the name of chars from which
ligature is formed, seperated by space. (GSUB entries will be created)

Infact PfaEdit can use for making working OpenType font for any
indian language, but now it will not assign the standared
features for indian languages (registred by Microsoft).
So after making a rough OTF font by using PfaEdit, 
you can manually edit the tables after dumping the 
font to XML by using TTX. (I mentioned about these things in a
prvious mail, please look into that)

I suggest all of you to use free tools for making free fonts.
and never use any propriatery softwares.

Baiju M
