<div style="direction:ltr;font-family:Tahoma;color:#000000;font-size:10pt">Dear all,<br>
<br>
I need the size of the oriented bounding box of a mask. <br>
I created a shape label object and extracted already some attributes (like nr. of pixels etc), what works pretty fine.<br>
Now I wanted to get the size of the oriented bounding box. But whatever I do and no matter which object I use, I always get the result [0, 0, 0]<br>
Is there a trick? <br>
<br>
Thanks a lot for your answer.<br>
<br>
