Description

The operator partition_linespartition_linespartition_linesPartitionLinesPartitionLines divides lines into two sets according to various criteria. For each input line the indicated features (FeatureFeatureFeatureFeaturefeature) are calculated. If each (OperationOperationOperationOperationoperation = 'and') or at least one (OperationOperationOperationOperationoperation = 'or') of the calculated features is within the given limits (MinMinMinMinmin,MaxMaxMaxMaxmax) the line is transferred into the first set (parameters RowBeginOutRowBeginOutRowBeginOutRowBeginOutrowBeginOut to ColEndOutColEndOutColEndOutColEndOutcolEndOut), otherwise into the second set (parameters FailRowBOutFailRowBOutFailRowBOutFailRowBOutfailRowBOut to FailColEOutFailColEOutFailColEOutFailColEOutfailColEOut). 

Condition:   Min_i <= Feature_i(Line) <= Max_i

Possible values for FeatureFeatureFeatureFeaturefeature:

'length'

(Euclidean) length of the line

'row'

Line index of the center

'column'

Column index of the center

'phi'

Orientation of the line (-pi/2 < phi <= pi/2)

Attention

If only one feature is used the value of OperationOperationOperationOperationoperation is meaningless. Several features are processed according to the sequence in which they are passed.

Result

The operator partition_linespartition_linespartition_linesPartitionLinesPartitionLines returns the value 2 (H_MSG_TRUE) if the parameter values are correct. Otherwise an exception is raised.
