[QUOTE=Kyatric] Use the expression len(text.text) (in case of a text object named text).
This system expression
will return the number of characters contained in the passed string.
From there try to multiply it by your font's size +/- X (for the space between the characters).[/QUOTE]
I do that but its only works with fixed size fonts like "courier new".
About use of others plugins I dont like so much because its not guaranteed to be compatible with future versions of C2, so I am asking that this feature is placed in the next release of C2.
