Issue 125153

Created attachment 83597 [details]
container with test files with applied GraphicRotation and macro

Select a Writer-picture and examine it with the Basic IDE. It supports the service SwXTextGraphicObject. The Basic IDE gives access to the property GraphicRotation, and you can set a value using a macro. Such macro is contained in file "Generated_by_AOO42.odt" in the attached zip-container.

In former versions, at least till AOO3.4, this results in a rotation of the picture around the top-left corner of the clip-rectangle set by the crop feature. You can open the attached files in AOO3.4 to see this.

Problems:
(1) The value of GraphicRotation is written as "svg:transform" attribute of the draw:frame element. But ODF 1.2 does not allow such attribute.

(2) The value is written in the meaning of "actual degree = value * 0.1", but SVG defines it as literal degree.

(3) AOO4.2 does not render the rotation.

(4) AOO4.2 writes the invalid attribute itself in a newly created document, if the value is applied by a macro.

(5) The property GraphicRotation is not mentioned in the API.

GraphicRotation should not be repaired in any kind, but superseded by a proper implementation of attribute draw:transform.

BTW, you need a graphic with transparency in AOO3.4, otherwise you get rendering errors when using negative crop values. Therefore a picture with palette and defined transparent color is used in the attached examples.
