Question

iDesktopX二次開發，将不(bù)封閉的(de)線對象通過方法convertToRegion轉成面對象，報錯“非法操作，不(bù)封閉的(de)GeoLine不(bù)可以(yǐ)被轉成面”，該如何解決？

Answer 1

【問題原因】數據存在(zài)拓撲錯誤，需要(yào / yāo)使用拓撲構面。 【解決辦法】使用TopologyProcessing.buildRegions方法構建面對象，在(zài)拓撲規則中設置以(yǐ)下規則： TopologyProcessingOptions topologyProcessingOptions = new TopologyProcessingOptions(); topologyProcessingOptions.setAdjacentEndpointsMerged(true); topologyProcessingOptions.setDuplicatedLinesCleaned(true); topologyProcessingOptions.setLinesIntersected(true);topologyProcessingOptions.setOvershootsCleaned(true); topologyProcessingOptions.setPseudoNodesCleaned(true); topologyProcessingOptions.setRedundantVerticesCleaned(true); topologyProcessingOptions.setUndershootsExtended(true); topologyProcessingOptions.setFilterMode(ArcAndVertexFilterMode.NONE);
