Description
The operator gen_rectangle2gen_rectangle2GenRectangle2GenRectangle2gen_rectangle2 generates one or more rectangles
with the center
(RowRowRowrowrow, ColumnColumnColumncolumncolumn) , the orientation PhiPhiPhiphiphi and
the half edge lengths Length1Length1Length1length1length_1 and Length2Length2Length2length2length_2.
The orientation is given in arc measure and indicates the angle between
the horizontal axis and the edge (with Length1Length1Length1length1length_1)
(mathematically positive).
The coordinate system runs from (0,0) (upper left corner) to
(Width-1,Height-1). See get_systemget_systemGetSystemGetSystemget_system and
reset_obj_dbreset_obj_dbResetObjDbResetObjDbreset_obj_db in this context.
More than one region can be created by passing one tuple of corner points.
Parameter Broadcasting
This operator supports parameter broadcasting.
This means that each parameter can be given as a tuple of length
1 or N.
Parameters with tuple length 1 will be repeated internally
such that the number of created items is always N.
Attention
The gray values of the output objects are undefined. For speed
reasons, the resulting region may contain additional pixels at the
border and some individual pixels at the border may be missing.
This may lead to an inconsistency between the operators
smallest_rectangle2smallest_rectangle2SmallestRectangle2SmallestRectangle2smallest_rectangle2 and gen_rectangle2gen_rectangle2GenRectangle2GenRectangle2gen_rectangle2.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.

Result
If the parameter values are correct the operator gen_rectangle2gen_rectangle2GenRectangle2GenRectangle2gen_rectangle2
returns the value 2 (
H_MSG_TRUE)
.
Otherwise an exception is raised.
The clipping according to the current image format is set via the
operator set_system('clip_region',<'true'/'false'>)set_system("clip_region",<"true"/"false">)SetSystem("clip_region",<"true"/"false">)SetSystem("clip_region",<"true"/"false">)set_system("clip_region",<"true"/"false">).
