G.copy

Hi,

For some observers I need the decomposed, removeOverlaped glyph.

I have sort of a solution by adding duplicate glyphs to the font and decompose, removeOverlap them. And automatically remove them when the observer was removed.

But I know this can be done in a nicer way. But this code doesn't do the trick. But why not? Seems okay to me...

f = CurrentFont()

g = f['H']

temp = g.copy()
temp.decompose()
temp.removeOverlap()
for c in temp.components:
    print c #these must be gone...
drawGlyph(temp)

<Component for I>

Who can help?
Thanks! Thom

Great, this works!
Thanks!

owke, this is idd not working cause a weakref object has to be referenced once or more.

you could force it with:

g = CurrentGlyph()

copy = g.copy()

# get the internal font and set it hard in the internal glyph object, even it is a copy
copy.naked().setParent(g.naked().getParent())

copy.decompose()
copy.removeOverlap()

print copy.components

Hi,

OK it draws. But still overlapped, and composed...

A copy has no parent anymore… so it cannot find the referenced glyph in a component. So decompose will not work.

Maybe the best option is to set the parent in the copied glyph:

source = CurrentGlyph()
g = source.copy()
g.setParent(source.getParent())
