Has anybody done this yet? Contextual replacement in OpenType using Kerning as the context.
I would like to offer a version of my font Army Pool Tiles ( which has kerning pairs ) in a reverse mode. Originally I thought I could just reverse the tiles but then I found I was getting unacceptable overlaps and gaps when the kerning was used ( suprise suprise) - so I need to create context dependent alternatives that fit correctly for the reverse font/s.
Has anybody here done this?
I am also just starting to learn this aspect of Fontlab. Does anybody have opinions about if it is better to code for contextual substitution in fontlab or with some 3rd part tool?
Update. I added an image which shows the kerning result. What the blue highlight is showing is the area I am concerned with in a reverse version of my font. In a reverse version the blue area would be mostly filled with tiles. When I apply a kern between the 'V' & 'a', the 'a' comes closer to the 'V'. Without substitution part of the V would be overlapped. What I plan to do is create an 'a' which has it's first line of tiles removed to substitute in when it occurs after 'V' (and some other glyphs). I have 298 pairs total.
If I get this working I will show the results.
