3d Type Vertical Alignment


Hello typophile fontlab users,

So I have this 5 layered font based on a painted font in fontlab.

I've figured out how to get the kerning exact so it aligns perfectly every time. My issue is the vertical settings.

In Illustrator or Photoshop, when using a text box, as opposed to clicking on canvas with type tool, Illustrator will adjust the baseline for each of the 5 layered styles.

Here is a picture of 2 of the font layers using the text box versus type path tool.

Is this something to do with vertical metrics? Am I missing a checkbox that says "keep original character positioning"?

Appreciate any advice.

Huge Cursor in Illustrator


For some reason in Illustrator I'm getting a giant cursor where text is added to the top. If you look at the picture you'll see the black portion is highlighted text. Despite the huge cursor the leading appears to be perfectly fine.

I'm not sure if this is related, but the ttf is cut off in MS Word and I'm assuming my vertical metrics are off...which is at least one of my problems if not both.

And for my dimensions:

Asc: 590
Des: -287
UPM: 1000

I've read the numerous articles about vertical metrics but something must still be off. Based on these values can anyone lend a hand on my OS/2 and hhea?

Draft of vertical metrics recommendations for web fonts

I've been trying to get to the bottom of how to best set vertical metrics in web fonts. These issues go way back, all the way to the creation of the TrueType format, which had separate Windows and Mac fields. Setting them wrong will lead to clipping, strange line spacing, and inconsistencies between browsers - sadly very familiar outcomes for people using web fonts. I'd like to make all that go away, and, just as important, make life easier for font designers, so they can just set the metrics and be confident they're right.

To _really_ understand vertical metrics on the web, I created some test cases and tested on a lot of browsers. I also came up with some draft recommendations, generally similar to the ones Typekit has been promoting.

Vertical Metric Configuration in Fontlab?

hello. i wondered if anyone could provide any help or advice with fontlab? at the moment it seems to have set a default descender of -250pt. the typeface i've created drops below this and when i test/generate the font all the descending glyphs are clipped slightly where the tails exceed the descender line.

i imagined dragging the descender below the lowest point would have solved the problem but it didn't seem to affect it. perhaps there is another way?

any help would be greatly appreciated.
