Description
The operator sort_contours_xldsort_contours_xldSortContoursXldSortContoursXldsort_contours_xld
sorts the contours
with respect to their relative position. RowOrColRowOrColRowOrColrowOrColrow_or_col
specifies the
sorting criteria:
'row'"row""row""row""row" sorts the contours with respect to the row coordinate of
their position first and, if the row coordinates are identical, with respect
to the column coordinate. In contrast, 'column'"column""column""column""column" sorts
contours according to the column coordinate first.
SortModeSortModeSortModesortModesort_mode
defines the position of a contour by individual reference
points. The following parameter values are available:
- 'upper_left'"upper_left""upper_left""upper_left""upper_left":
-
The position is determined by the upper left corner of the
surrounding rectangle.
- 'upper_right'"upper_right""upper_right""upper_right""upper_right":
-
The position is determined by the upper right corner of the
surrounding rectangle.
- 'lower_left'"lower_left""lower_left""lower_left""lower_left":
-
The position is determined by the lower left corner of the
surrounding rectangle.
- 'lower_right'"lower_right""lower_right""lower_right""lower_right":
-
The position is determined by the lower right corner of the
surrounding rectangle.
- 'character'"character""character""character""character":
-
The position is determined by the upper left corner of the
surrounding rectangle. In contrast to 'upper_left'"upper_left""upper_left""upper_left""upper_left",
the contours
are also sorted according to the remaining coordinate, if they
overlap in
the direction of the coordinate which is specified by the
parameter RowOrColRowOrColRowOrColrowOrColrow_or_col
.
The parameter OrderOrderOrderorderorder
determines whether the
sorting order is increasing or decreasing: using
'true'"true""true""true""true" the order will be increasing, using
'false'"false""false""false""false" the order will be decreasing.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
