How does Text2Path set the coordinates

[shine-flower]

How to change the coordinates of path, currently the default is (0,0).

The render base point is always (0, 0) but the functions of the text2path add-on return Path objects, which have a transform() method.

The transformation matrix can be composed from multiple Matrix44 instances by multiplying them or use the Matrix.chain() class-method or the helper function ezdxf.math.basic_transformation(). Always follow the order: scale, rotate, move.

from ezdxf.math import Matrix44, basic_transformation
from ezdxf.addons import text2path
from ezdxf import path

# create transformation matrix m
m = Matrix44.chain(Matrix44.scale(...), Matrix44.z_rotate(...), Matrix44.translate(...))

# helper function to create a transformation matrix:
m = basic_transformation(move=..., scale=..., z-rotate=...)

# transform a single-path object 
p1 = text2path.make_path_from_string(...)  # returns a multi-path object
p1 = p1.transform(m)  # creates a new Path object!

# transform multiple single-path objects
paths = text2path.make_paths_from_string(...)  # returns a list of single-path objects
paths = path.transform_paths(paths, m)
