select_lines_longest ( : : RowBeginIn, ColBeginIn, RowEndIn, ColEndIn, Num : RowBeginOut, ColBeginOut, RowEndOut, ColEndOut )
Select the longest input lines.
The operator select_lines_longest selects the
Num longest input lines from the input lines described by
the tuples RowBeginIn, ColBeginIn,
RowEndIn and ColEndIn.
Parameters

line.begin.y-array -> integer
|
|
Row coordinates of the starting points of the
input lines. |
ColBeginIn (input_control)
|
line.begin.x-array -> integer
|
|
Column coordinates of the starting points of the
input lines. |
RowEndIn (input_control)
|
line.end.y-array -> integer
|
|
Row coordinates of the ending points of the
input lines. |
ColEndIn (input_control)
|
line.end.x-array -> integer
|
|
Column coordinates of the ending points of the
input lines. |
Num (input_control)
|
integer -> integer
|
|
(Maximum) desired number of output lines. |
|
Default value: 10 |
RowBeginOut (output_control)
|
line.begin.y-array -> integer
|
|
Row coordinates of the starting points of the
output lines. |
ColBeginOut (output_control)
|
line.begin.x-array -> integer
|
|
Column coordinates of the starting points of the
output lines. |
RowEndOut (output_control)
