Description

The operator get_region_runsget_region_runsget_region_runsGetRegionRunsGetRegionRuns returns the region data in the form of chord tuples. The chord representation is caused by examining a region line by line with ascending line number (= from “top” to “bottom”). Every line is passed from left to right (ascending column number); storing all starting and ending points of region segments (= chords). Thus a region can be described by a sequence of chords, a chord being defined by line number, starting and ending points (column number). The operator get_region_runsget_region_runsget_region_runsGetRegionRunsGetRegionRuns returns the three components of the chords in the form of tuples. In case of an empty region three empty tuples are returned.

Attention

Only one region may be passed.

Result

The operator get_region_runsget_region_runsget_region_runsGetRegionRunsGetRegionRuns normally returns the value 2 (H_MSG_TRUE). If more than one region is passed an exception is raised. The behavior in case of empty input (no input regions available) is set via the operator set_system('no_object_result',<Result>)set_system("no_object_result",<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>).
