Description Regina Henschel 2010-02-10 19:56:28 UTC 
The attached document contains the macro “Change Shape via Matrix”. It reads the
property “Transformation” from the selected shape, multiplies it with the matrix
(1 -1 0   1 1 0  0 0 1) (read row wise) and writes the result back to the
property. When applying the macro, the shape should perform a 45°-rotation and
enlarge with factor sqrt(2). So when applying the macro twice you get a shape,
which is rotated with 90° and has double size.
Set a break point in the macro “Examine shape” and watch the object “oShape” to
see this property.

Open the attached document and select the measure line. Apply the macro several
times. Watch that the measure line rotates and resizes one time, but then no more.

Reset assigne to the default "issues@openoffice.apache.org".
Comment 4 Regina Henschel 2020-11-15 19:12:33 UTC 
It seems to be an implementation error in TRSetBaseGeometry and TRGetBaseGeometry, done in bug 97878.
The intension was, to handle the matrix operations same as path objects. But for that purpose the second parameter is missing. Currently the matrix is applied to a line from (0|0) to (1|0) in TRSetBaseGeometry, but the matrix from TRGetBaseGeometry does only contain scale and translate. Thus a chain of these matrix operations does not work.
