Queries the selected DTW object for the time along the minimal path given the time along the "xdirection". This command is deprecated, the new commands for querying are DTW: Get y time from x time... and DTW: Get x time from y time....
When the input time is in the interval [xmin, xmax], the returned time will be in the interval [ymin, ymax], where [xmin, xmax] and [ymin, ymax] are the domains of the two "objects" from which the DTWobject was constructed.For all other input times we assume that the two object are aligned.
We like to have a "continuous" interpretation of time for the quantized times in the x and y direction; we make the path piecewise linear. There are two special cases:
1. The local path is horizontal. We calculate the ytime from the line that connects the lowerleft position of the leftmost horizontal time block to the upperright position of the rightmost horizontal time block.
2. The local path is vertical. We calculate the ytime from the line that connects the lowerleft position of the bottommost vertical time block to the upperright position of the topmost horizontal time block.
