example ligature code.

[David Tooke]

Does anyone have any example code demonstrating how to use the GSUB extensions to handle ligatures?

 

I am rendering some arabic using the arial font.   The text looks like it should have a ligature substitution; but none is happening even though I am using the "liga" feature.

 

I know I am doing something wrong, but I would grateful for any assistance.

 

Thanks in advance
