Hello everybody!
I am trying to flip horizontally the rectangles of xml cascade. For normal rectangles, without tilt, I simply use rect.x = img_width - rect.x - rect.width.
But, aparently, that equation does not apply when the rectangle is tilted. When the rectangle is tilted we have the following marks in xml cascade : <tilted>1</tilted>
Someone, please, could help to understand to to flip tilted rectangles in the xml cascade?
