package com.luciad.view.lightspeed.label.algorithm.discrete

Handles discrete labeling algorithms.

The main class in this package is ALspDiscreteLabelingAlgorithm. This class provides an abstract implementation of ILspLabelingAlgorithm that makes it easier to implement, customize and compose algorithms.

This package contains a few ALspDiscreteLabelingAlgorithm implementations :

• TLspLabelingAlgorithm : This algorithm tries a fixed number of custom label locations.
• TLspOnPathLabelingAlgorithm : This algorithm tries to place the labels on a path.
• TLspCurvedPathLabelingAlgorithm : This algorithm tries to place curved text labels on a path.
• TLspInPathLabelingAlgorithm : This algorithm tries to place the labels inside a (polygonal) path.
• TLspCompositeDiscreteLabelingAlgorithm : This algorithm can be used to compose ALspDiscreteLabelingAlgorithms.
• TLspDependentLabelsRemovalWrapper : This algorithm wrapper defines a dependency which can be used to define if labels are omitted based on the omitting of other labels.
