Question about <MeasurementUnit>

[RoxPoNinja]

Hi @kermitt2,
In the Description tag the MeasurementUnit is said to be "pixel", but the height, weight & coordinates have values like these "HPOS="75.1181" VPOS="69.4485" HEIGHT="8.5140" WIDTH="274.993", which don't really make sense if we're talking about pixels. Is it maybe that the measurement unit is mm10 (1/10 of mm), which is the default (https://github.com/altoxml/documentation/wiki/ALTO-element-set)? Thanks!
