Constructor.
- Parameters:
-
image_width width of the image image_height height of the image center_x x-coordinate of the center point center_y y-coordinate of the center point num_rays number of rays radius_incr number of pixels by which the radius is increased yuv_mask a mask allows to exclude certain regions of the image from inspection. More precisely, no scanline points are generated in those areas. The ignored regions have to be black, i.e. Y=0, U=127, V=127. dead_radius number of pixels around the center that are disregarded max_radius maximal radius in number of pixels margin margin around every scanline point that does not contain any other scanline point (in pixels)

- Returns:
- current point in image that is shall be processed.
Implements ScanlineModel.
| point_t * ScanlineStar::operator++ | ( | int | ) | [virtual] |
