How to detect slope angle/ slant angle of text?

I have a word with italic font, I want to know the degree of slope of the piece, how to detect the slope of the text using Matlab?

I try to use methods of radon transform, but i dont understand the meaning of radon transform degrees column Of Max angle, I compare writings that have been straight to the italics, why the max angle is same? 142 and 141?

the top is the initial image, the bottom is the result of imwrap, I want to use max angle as the limit to set imwrap, but hindered by the constraints of his Column max angle can not be distinguished, between italics and upright words

please help me in solving this problem, thank you very much
