Get path ids of all selected paths should be of all paths in "Glyphs" layer
|
||||||
|
Put all ids into a continueous string (no separation character) and paste as text element in layer Ids at position x 0 y 0.
|
||||||
|
Paths are sorted by left bounding box.
|
||||||
|
Intention:
|
||||||
|
to quickly retrieve all path-ids of the glyph-paths when using the Custom Stroke Font extension to edit a existing svg font https://github.com/Shriinivas/inkscapestrokefont
|
||||||
|
this string of ids can then be used to set ids using setIds.py as ids might be lost in different path operations. https://gitlab.com/EllenWasbo/inkscape-extension-setIds

What do we want to check?
|
||||||
|
=========================
|
||||||
|
|
||||||
|
* any text objects that are not converted to a path?
|
||||||
|
* can be implemented as tag blacklist
|
||||||
|
* any outlines? they need to be converted to paths
|
||||||
|
* check for crossing paths
|
||||||
|
* this is the hardest
|
||||||
|
* for lines, this is easy, and can, for example, be done with shapely:
|
||||||
|
|
||||||
|
>>> from shapely.geometry import LineString
|
||||||
|
>>> l1 = LineString([(0, 0), (1, 1)])
|
||||||
|
>>> l2 = LineString([(0, 1), (1, 0)])
|
||||||
|
>>> l1.intersects(l2)
|
||||||
|
True
|
||||||
|
>>> p = l1.intersection(l2)
|
||||||
|
>>> p.x
|
||||||
|
0.5
|
||||||
|
>>> p.y
|
||||||
|
0.5
|
||||||
|
* check for self-intersection, too (=> line.is_simple)
|
||||||
|
* need to split each complex subpath into its segments
|
||||||
|
* then, when doing intersections, remove the `boundary`
|
||||||
|
from the intersection set, because two adjacent
|
||||||
|
segments from a subpath always intersect in their boundary
|
||||||
|
* handle the commands M, Z, L, C, Q, A (parsed via simplepath)
|
||||||
|
* M: moveto
|
||||||
|
* Z: closepath (straight closing line)
|
||||||
|
* L: lineto
|
||||||
|
* C: curveto (cubic bezier)
|
||||||
|
* Q: curveto (quadratic bezier)
|
||||||
|
* A: elliptical arc (circles, ellipsis)
|
||||||
|
* paths need to have a minimum distance to other paths
|
||||||
|
* if two paths are connected ("T-junction"), this junction needs to be
|
||||||
|
exempt from the distance check.
