Hi,
Again in need of some help
I am currently working on a handwriting font (letters are connected to each other) which has couple of different versions of each letter, depending on the location of the connection to the previous and the following letter. Now, how do I do that the correct “version” of the letter will appear when typing? I named the letters (example: a.hl - h standing for the high point connection, and l standing for the low point connection).
Can anyone explain/help me solve this? Do I do this with contextual ligatures by hand or is there any other way?
Thanks so much for your help.
Of course because of the order of the lookups the font always starts with the INITIAL_L lookup. SO I was wondering how could I make the font engine to loop between the two lookups? So one would get choosen each time you start to type.
Or am I going in totally the wrong direction?
The way you want it, I am afraid it is impossible (unless I am misunderstanding it somehow, because I am not quite sure what exactly you are aiming at with the code).
But what you could do is split the letters into groups so that every word will behave differently, i.e. what the user types becomes the randomisation. There is an example in the Advanced Contextual Alternates tutorial.
I assume you are doing something similar already, but I cannot tell what these groups are.
HI,
Sorry for not explaining it properly. As stated in the first post I am trying to do a handwriting font that would be as close to the original handwriting.
I have classes of letters (.ll001, .ll002, .ll003, .lh001, .lh002, .lh003,…) first letter stand for the stroke that comes into the letter (lowercase letters) and second letter stands for the stroke that comes “out” of the letter (“h” stands for high, “l” stands for low and “n” stands for no connection). Every class with the same attributes (hh,ll, nn, ln, lh,…) has three versions (001, 002, 003). Which means I have 27 classes of the letters.
What I am trying to do now is to make everything go along together, but since I am no expert whatsoever in Opentype features I am confused and lost now
Did I do better at explaining it this time?
Thank you so much for your help.
I am still not quite sure how I can help you. You can exchange glyphs based on their context, but you know that already. Perhaps you want to read through Tal’s OpenType cookbook to get a grip of the various techniques.
In any event, you need to think in steps which you can cage into lookups.
And maybe you want to rethink your system, because telling from what you write, it looks like there sometimes are more than one possibility to connect the same letters. Is that right?
Thanks for the advice. I read through OpenType cookbook a couple of times now
Yeah, that’s right. There is more than one possibility for the connection…
I wanted to create a font that would choose the next letter base on the letter before it… and at the same time cycle through 3 different alternates of this letter.
You mean to make opentype features for all the connections?
I made that but, the problem is how to switch between the high and low connections… I think I got myself in a way bigger problem than I can handle. I thought there must be a way to make opentype choose between two of the lookups that have the same importance… Probably I am talking in a way you don’t even know what I mean i am sorry about that.
And thank you for all your patience & help.
If we look at the example above… I have different letters depending if there is a letter on the beginning of the word, end, middle or isolated. In the middle my letters cycle between 1st, 2nd or 3rd alternate of the letter. But my problem is to make them cycle with the isolated, initial and final letters. Is there way to make this cycle as well?
Does anybody have an idea how to make them cycle?
I guess I should buy you a couple of beers after this one.
Well, everything is working now in glyphs preview. But when I exported it (.otf of course), the calt feature and the dlig features are working (Adobe Ilustrator) but the fina, isol and init are not
They don’t work automatically, and I believe, are not supported in AI. But you can put them into calt as well. Take a look at the positional feature tutorial.
Yes, I see they don’t.
The problem is then I am back to the beginning because my problem was solved by the use of positional features. I made my features like you proposed above, but am in need of this working automatically…
“One way is to:
put the cycles in calt,
put calt after the positional features,
repeat the positional features in lookups inside calt,
add the cycle code in separate lookups at the end of calt,
and include the positional forms in the cycling classes.”
