iTextSharp units

Question

Anyone knows what unit system does iTextSharp uses? My first assumption would be pixels but I'm not sure about it.

Thanks!

EDIT: Sorry to not being more specific, and thanks for letting me know. I'm talking about units for measures in the PageSize and Margins.

Answer 1

If I remember correctly it uses "points", the same unit of measurement as a font (as PDF is centered around correct font rendering).

One "point" is 1/72 of an inch (or about 0.353mm).

Answer 2

pointsValue = iTextSharp.text.Utilities.MillimetersToPoints(mmValue)
