Hi Don,
Thank you for the help.
I need create the text object at runtime, so I cannot use CR Designer.
Because I working a web application, as I know there is no javascript function to get screen size in mm or inch.
I checked some functions that converts twips to pixels. But these seem work on for windows or desktop application, in that case, the both screen size and pixels can be retrieved. But in web case, I can only get pixels.
