Subject: [OASIS Issue Tracker] Created: (OFFICE-3848) Error in matrix description in 19.107 dr3d:transform
Error in matrix description in 19.107 dr3d:transform
----------------------------------------------------
Key: OFFICE-3848
URL: http://tools.oasis-open.org/issues/browse/OFFICE-3848
Project: OASIS Open Document Format for Office Applications (OpenDocument) TC
Issue Type: Bug
Components: Graphics
Affects Versions: ODF 1.2
Reporter: Regina Henschel
Priority: Trivial
Fix For: ODF 1.2 Errata 01
Text in 19.107 dr3d:transform is
"matrix(<a> <b> <c> <d> <e> <f> <g> <h> <i> <j> <k> <l>): specifies a transformation in the form of a transformation matrix of twelve values. The values describe a standard 4x3 homogeneous transformation matrix in column-major order, where the right column (<j>, <k>, <l>) describes the translation. "
There "4x3" is wrong. The full transformation matrix is
a d g j
b e h k
c f i l
0 0 0 1
That is a 4x4 matrix.
Or if you drop the fix value forth row, which corresponds to "matrix of twelve values", you get
a d g j
b e h k
c f i l
That is a 3x4 matrix.
So in both cases it is not a 4x3 matrix.
