If the bounds are
470.898438
195.54686
258
124.729149
The PrintDocumentSize is
765.1415
809.1926
If the bounds are
470.898438
195.54686
258
139.8203
The PrintDocumentSize is
770.1719
809.1926
If the bounds are
470.898438
195.54686
258
154.911438
The PrintDocumentSize is
775.2023
809.1926
And this goes on...
I need for the PrintDocumentSize width to be 765.1415 regardless of the size of the GoObject
