Hi,
the OOXML standard specifies for the wrapPolygon element (§20.4.2.16) the type CT_WrapPath. It is a sequence of one element "start" and at least two elements "lineTo". These have the type CT_Point2D. That has the attributes "x" and "y" with values of type ST_Coordinate. Such can be a ST_CoordinateUnqualified or a ST_UniversalMeasure.
Word does not write units but pure numbers, so uses ST_CoordinateUnqualified. The standard specifies in §20.1.10.19, that this numbers have to be in unit EMU.
But Word does not interpret this values as having unit EMU. From what I see in the file, I guess, that Word uses the numbers unitless, so as if the shape rectangle has a CoordSize "21600 21600".
Is this observation correct? If yes, this needs to be documented.
Kind regards
Regina
