I am currently using computer vision tool box in my Matlab and I have some issues with the function insertObjectAnnotation. It only imports textbox in landscape (text goes from left to right). How could I change it so the text inside the textbox is still in landscape but the textbox is rotated 90 degrees counter-clockwise? Thank you very much for your help.

Hi Chen,

Unfortunately this is not possible at present. insertText and insertObjectAnnotation do not let you rotate the text.

Thank you for your answer. I tried multiple other ways with no good I suppose I should just stop here.

Actually, wait. Maybe you can do it. You can rotate the image, call insertObjectAnnotation, and then rotate the image back.
