Re: [dev] Using matrices for rotation of graphical objects
Hi Regina, Ok I will try to ask on d...@api.openoffice.org. Thank you very much.

I'm not sure whether this is a defect or desired behavior. In my experiments I see this behavior: When you apply the new matrix, the translation part of it is used for "from left to paragraph area" and "from top to margin". That is true for all anchor types of form "to". Anchored "as Character" it is "from bottom to base line" vertically, horizontal part is ignored.

Re: [dev] Using matrices for rotation of graphical objects
Hi, I use a trick to rotate the image : I convert the image (which is a com.sun.star.text.TextGraphicObject object) into com.sun.star.drawing.GraphicObjectShape object. It is this new object that I want to rotate. Best regards, T.
