Hello.

Just wanted to give some Text a perspective, following this guide:
https://ahninniah.blogspot.com/2013/05/drawing-in-perspective-with-inkscape.html

After typing text, transformed to path, ungrouped, and then unified. After that I tried to use the perspective extension.

The following error occurs:
Traceback (most recent call last):
  File "perspective.py", line 136, in <module>
    Perspective().run()
  File "C:\Program Files\Inkscape\share\inkscape\extensions\inkex\base.py", line 131, in run
    self.save_raw(self.effect())
  File "perspective.py", line 64, in effect
    bbox = obj.bounding_box(obj.getparent().composed_transform())
  File "C:\Program Files\Inkscape\share\inkscape\extensions\inkex\elements\_base.py", line 165, in __getattr__
    raise AttributeError(f"Can't find attribute {self.typename}.{name}")
AttributeError: Can't find attribute SvgDocumentElement.composed_transform

Can anybody help me here?

Thank you for reading the post.
Johnny.

Same error here - but you can try LPE Perspective/Envelope:

The extension is working as expected here... 1.1.1 on Win and Linux Mint.

I can reproduce the error in 1.1.1 when using a template with no layers.

Yup - that´s it; not working in "roots".

Thank you Polygon, your solution did help me out, and gave me additional tools, too. Tools I did not know before (within the path effects).

To the others: Thank you for checking and finding, where the error comes from!
