i have a text field

in which from character 1-9 its bold italic and with blue color

character 12-14 some different properties

but now if i'm selecting align center then it automatically changes
the color of whole text according to selected color.

in getTextFormat () method

its written:

Any property that is mixed, meaning that it has different values at
different points in the text, has a value of null.

is there is any method to solve this problem.
