Panotools::Script::Line::Control - Panotools control-point
A pair of control-points forms a 'c' line
One line per point pair. about one pair of points per image per variable being optimized. The more variables being optimized the more control points needed.
n0 first image N1 second image x1066.5 first image x point position y844.333 first image y point position X239.52 second image x point position Y804.64 second image y point position t0 type of control point (optional) 0 - normal (default) 1 - optimize horizontally only 2 - optimize vertically only 3+ (all other numbers) - straight line
Get a simplified description of a control point useful for identifying duplicates like so:
Format is first image, x, y, second image, x, y, point type
Get a value for control point error distance (measured in pixels in the panorama output):
print $point->Distance ($pto);
Note that it is necessary to pass a Panotools::Script object to this method. Note also that the values returned are approximately half those returned by panotools itself, go figure.
