disp_arcdisp_arcDispArcDispArcDispArc displays one or several circular arcs in the
output window. An arc is described by its center point
(CenterRowCenterRowCenterRowCenterRowcenterRow,CenterColCenterColCenterColCenterColcenterCol), the angle between start and end
of the arc (AngleAngleAngleAngleangle in radians) and the first point of the arc
(BeginRowBeginRowBeginRowBeginRowbeginRow,BeginColBeginColBeginColBeginColbeginCol). The arc is displayed in clockwise
direction. The parameters for output can be determined - as with the output
of regions - with the operators set_colorset_colorSetColorSetColorSetColor, set_grayset_graySetGraySetGraySetGray,
set_drawset_drawSetDrawSetDrawSetDraw, etc. It is possible to draw several arcs with
one call by using tupel parameters. For the use of colors with
several arcs, see set_colorset_colorSetColorSetColorSetColor.
The center point has to be within the window. The radius of the arc has be
at least 2 pixel.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
