Created attachment 170448

Document for testing rotation angles.

The current text is:
RotateAngle
::com::sun::star::drawing::EnhancedCustomShapeParameterPair RotateAngle
        optional property

This attributes specifies the rotation angle about the x-axis in grad.

The order of rotation is: z-axis, y-axis and then x-axis. The z-axis is
specified by the draw:rotate-angle.


Errors:
A) The Attribute is a pair of parameters and determines the angle for rotation
about x-axis and about y-axis.
B) The unit is 'degree' not 'grad'. For 'grad' see
https://en.wikipedia.org/wiki/Gradian
C) 'draw:rotate-angle' does not exist.
D) Inside the API, an API attribute should be referenced for the rotation about
the z-axis, no ODF XML.

Proposed text:
This attribute specifies rotation angles. The first parameter specifies the
rotation angle about the x-axis in degree. The second parameter specifies the
rotation angle about the y-axis in degree. Rotation about the z-axis is
specified via Transformation attribute of service Shape.
The order of rotation is z-axis, y-axis and then x-axis.

Remark:
There exists in addition the attribute RotateAngle of service
RotationDescriptor for the rotation about the z-axis with unit 1/100 degree.
But that is deprecated. Perhaps add it nevertheless, because the usage is
easier? The angle for the rotation about the z-axis is not directly given in
the transformation matrix, but you need to decompose the matrix.


I have attached a document with macro, so that you can examine an object which
has extrusion.
Tools > Macros > Edit Macros
Go to macro examineShape_inDraw and set a break point at 'dummy=1'. Back to
document.
Select object, press Alt+F11 and run macro examineShape_inDraw.
Go to Basic IDE and look at oShape in Watch-window.

Rotations about x- and y-axis are in toolbar "3D-Settings". Rotation about
z-axis is in Position&Size dialog.
