sort_region--to sort a region

The operator sort_region sorts the regions with respect to their relative position. All sorting methods with the exception of ' character ' use one point of the region.

The following values is available for the parameter sortmode:

' Character '

The regions would be treated as characters in a row and would be sorted according to their order in the Line:if NS overlap horizontally, they'll be sorted with respect to their column values, otherwise they would be sorted with Regar D to their row values. To is able to sort a line correctly, all regions in the line must overlap each other vertically. Furthermore, the regions in adjacent rows must not overlap.

' First_point '

The point and the lowest column value in the first row of the region.

' Last_point '

The point and the highest column value in the last row of the region.

' Upper_right '

Upper right corner of the surrounding rectangle.

' Lower_left '

Lower left corner of the surrounding rectangle.

' Lower_right '

Lower right corner of the surrounding rectangle.

The parameter order determines whether the sorting order is increasing or decreasing:using ' true ' the order would be incre Asing, using ' false ', the order would be decreasing.
