What coordinate system is used

[Igor Korot]

Hi, ALL,

In https://docs.wxwidgets.org/latest/classwx_read_only_d_c.html#a8b959eb99f2f306f9666304c929441e8
(GetTextExtent) it would be nice if it was mentioned whether the pixels,
points or inches is used to retrieve the size is used.

I presume that the size is returned in points.

Thank you.

All wxDC operations use logical units, which are normally mapped to pixels. See https://docs.wxwidgets.org/latest/classwx_d_c.html#:~:text=Device%20and%20logical%20units

Thx for the response.

Now I need to figure out a simple way to convert the value I receive to
inches/millimeters.
