Missing positional argument in geodata example

[iembry]

Hi everyone, I used the following code to test the DXF file used in the geo_interface example:

import ezdxf
from ezdxf import transform
from ezdxf.math import Matrix44

CRS_TO_WCS = True

doc = ezdxf.readfile("Graz_10km_3m.dxf")
msp = doc.modelspace()
geo_data = msp.get_geodata()


def wcs_to_crs(entities, m):
    transform.inplace(entities, m)

def crs_to_wcs(entities, m):
    m = m.copy()
    m.inverse()
    transform.inplace(entities, m)

if geo_data:
    # Get the transformation matrix and epsg code:
    m, epsg = geo_data.get_crs_transformation()
else:
    # Identity matrix for DXF files without a geo location reference:
    m = Matrix44()
    epsg = 3395

if geo_data:
    m, epsg = geo_data.get_crs_transformation()
    if CRS_TO_WCS:
        crs_to_wcs(msp)
    else:
        wcs_to_crs(msp)
else:
    print("No geo reference data available.")

Upon executing the above code, I received the following error message:

Traceback (most recent call last):
  File "/usr/lib/python3.10/idlelib/run.py", line 578, in runcode
    exec(code, self.locals)
  File "roadmap.py", line 34, in <module>
    crs_to_wcs(msp)
TypeError: crs_to_wcs() missing 1 required positional argument: 'm'

I then attempted the following code to see if it would fix the error, but I received the following message:

if geo_data:
    m, epsg = geo_data.get_crs_transformation()
    if CRS_TO_WCS:
        crs_to_wcs(m)
    else:
        wcs_to_crs(m)
else:
    print("No geo reference data available.")


Traceback (most recent call last):
  File "/usr/lib/python3.10/idlelib/run.py", line 578, in runcode
    exec(code, self.locals)
  File "roadmap.py", line 34, in <module>
    crs_to_wcs(m)
TypeError: crs_to_wcs() missing 1 required positional argument: 'm'

What corrections need to be made in the above code?

Thank you.

    m, epsg = geo_data.get_crs_transformation()
    if CRS_TO_WCS:
        crs_to_wcs(msp, m)
    else:
        wcs_to_crs(msp, m)
else:
    print("No geo reference data available.")

OK. Thank you for the prompt response with the corrections. Your code revisions worked perfectly.
