Differentiating Anchor Types

Post by tjdickinson » Thu May 11, 2017 11:10 am

I don't understand the proper application of the anchor types "mark" and "base". Does a "base" anchor only go on the base glyph, and the "mark" anchor only on the mark glyph? Or do you put a "mark" anchor on the base glyph to show where the mark sits, and a "base" anchor on the mark glyph to show where it attaches to the base? Or does a glyph contain both the mark and base anchor types?
Thank you!

Thanks for your response! Yes, I did read that, and all the other instances of "anchor" in the documentation. But none of it explained (at least, as far as I could glean) how to assign anchors from the Add Anchor tool in glyph edit mode. I have the option to add a "base" or "mark" anchor, but it's not clear to me which to use in what scenario.
Thank you!

Yes.

When you add an anchor to a base glyph it should be a 'base' type anchor, when you add an anchor to a diacritic mark it should be a 'mark' type anchor.

Then if that diacritic mark character is used following the character which has an anchor of the same name the rendering program will line up the two anchors so that they are in the same position, it does this by moving the character with the 'mark' type anchor, the character with the 'base' anchor does not have it's position altered.

Two consecutive glyphs with 'base' anchors of the same name will have no effect, their positions will not be altered. Two consecutive characters with 'mark' type anchors of the same name will have no effect and their positions will not be altered.

Any questions ? :wink:
