Hello Glyphs! I am a late adopter to Glyphs3 and only just purchased it, so forgive me if this has already been discussed; I have tried searching for similar issues but I fear it might be something unique to me.
So I rely on a lot of scripts using robofab and pens, over the years I have managed to adapt them for FontLab/RoboFont/Glyphs2, but I discovered that when I use pens in Glyphs3 it appears to double the processed glyph in size.
The simplest example of this is when copying a glyph and then appending it as shown below.
I beleive that under the hood this is using pens, and for me the result is the appending glyph is 2x the size as it was originally.
I have tested with other pen examples with the same result (longer code example at end)
I have tested this on newly created Glyphs3 files @ 1000upm as default, and I have got the same result on files created in Glyphs2 @ 2000upm.
I have installed all of the modules from the plugin manager including Python for Glyphs which I have selected as my python environment and the app has been restarted multiple times.
I still have glyphs2 installed and the problem does not happen there.
Please let me know if you need more information, and if there’s anything I can do to help debug, I would just like to get this behaving as expected so I’m more than happy to provide anything you need.
Thanks, Matt
from robofab.world import *
# get Current Glyph
cg = CurrentGlyph()
# make a copy of Current Glyph
cgcopy = cg.copy()
# clear the Current Glyph
cg.clear()
# append the copy (shifted 100,100 helping to show a change was made if it was working correctly glyph would appear to move but remain same size, in my case it also doubles in size)
cg.appendGlyph(cgcopy,(100,100))
