Image Size Not Applied when opening OpenXML Word Document Created in C# -

-

i creating openxml word document inside c# web application , writing google chart image it. i'm specifying dimensions of image, seems, correctly. however, when open word document, image right height, not right width. in fact, square.

when click on image inside of word , go size , position, correct dimensions displayed. in case, 2.08" 5.04". when click "ok" after changing nothing, image stretches right size.

if try identify size appears as, close half defined width, may coincidence.

the native size of image 3.13" (h) 7.55" (w), doesn't seem should matter.

i followed following posts pretty closely:

i'm guessing i'm missing setting of sort, don't know one. paragraph or run need sized entire width of page? width of document need specified?

according code, have set cx , cy values both extent properties.

new dw.extent() { cx = widthemus, cy = heightemus }

first 1 inline , second transform2d.
