More off curve issues

[Dick Pape]

Now that it's been mentioned, I too am having problems with off curve extremes. And I have the pictures to prove it:

The problem is an inconsistency in moving and reporting glyphs due to off curve points not being treated as part of a curve apparently.

This situation occurs on left side, right side or descender side (and probably ascender side also).

Setup:
a. Using Transform tool bar to move a glyph into position, such as 0,0.

b. Looking at Font Information there is a -1 Min Left Side bearing. Why?

c. Off curve point is -1...

Once it's seen the manual fix is trivial. Might there be a permanent fix in the offing? Dick

There is a difference between the visual bounding box, and the bounding box that includes all points. Most of the time these are equal, but not when your glyph has global off-curve extreme coordinates.

That said, it seems you've encountered a rounding issue. I would really like to look into your example, so please send me the font file and instructions on how to reproduce it.

Hi Erwin

It's not unique to this font. I tried a quick test and same problem showed up.

Setup: Align a glyph to x=0. Add one off curve point at the left side of the glyph and drag it left (distance doesn't matter). Realign glyph back to x=0 and the off curve point will be -something. (One I'm playing with is -43).

Glyph as a whole is aligned x=0 but the point is not. X Minimum will be -something.

I don't know. This off curve point is never included within a box afaics.

This is how it's supposed to be. I thought your point was related to rounding errors. I didn't write the specs, but I can add more Font Information, e.g. visual X min, etc.
