delete_contour

Synopsis

Delete the specified contour.

delete_contour()
delete_contour( [ChipsId] )
delete_contour( "contour_id" )
delete_contour( "all" )

Description

Depending on the argument, the delete_contour command deletes the current contour, the contour indicated in a ChipsId structure or by the contour_id, or all contours.

• (no argument) - the current contour is deleted.
• ChipsId - an optional ChipsId structure containing values to modify the currency state for the command.
• contour_id - identification tag given to each object that is created; use this to delete a specific contour.
• all - deletes all contours.

Example 1

chips> add_contour([[1,1,1], [1,3,1], [1,1,1]], 3,3)
chips> delete_contour()

Create a contour, then delete it.

Example 2

chips> id = ChipsId()
chips> add_contour([[1,1,1], [1,3,1], [1,1,1]], 3,3,
[1.1,1.5,2,2.5],'id=levels')
chips> add_contour([1,2,5,3,3,6,0,0,1],3,3)
chips> id.contour = "levels"
chips> delete_contour(id)

Two contours are created; the second contour is current after it is created. The id.contour command sets the contour value of the ChipsId structure to the first contour. That contour is then deleted.

Example 3

chips> add_contour([[1,1,1], [1,3,1], [1,1,1]], 3,3,
[1.1,1.5,2,2.5],'color=lime style=solid')
chips> add_contour([1,2,5,3,3,6,0,0,1],3,3)
chips> delete_contour("all")

Two contours are created, then the delete_contour command deletes them both.
