How to Determining TextFrame Position in IDML Using XML and Python: Handling Negative Values

[Zective]

After extracting the IDML file, I checked the `TextFrame` elements in the `Spreads.xml` file.

However, when I calculate the position using a matrix, I get negative values.

The document size and the `TextFrame` size are calculated correctly, but I’m not sure how to properly calculate the position.

Can you help me with this?

* I am using Python.

Hi,

Coordinate spaces in IDML are detailed in the specification. The origin of the Spread space is its center point:

Then you use ItemTransform and PathGeometry elements to get space-relative coordinates, in pt.
