使用图层

链接图层的支持

链接图层类似于对图层进行分组。如果您链接了两个或多个图层，那么将允许您对所有链接的图层进行某些更改。例如，如果您对一个图层应用了变换，则将应用到所有其他链接的图层。本文演示了如何使用Aspose.PSD for Java获取和取消链接图层。

        String dataDir = Utils.getDataDir(SupportOfLinkedLayer.class) + "ModifyingAndConvertingImages/";
        
        PsdImage psd = (PsdImage) Image.load(dataDir + "LinkedLayerexample.psd");
        try {
            Layer[] layers = psd.getLayers();


            short layersLinkGroupId = psd.getLinkedLayersManager().linkLayers(layers);


            short linkGroupId = psd.getLinkedLayersManager().getLinkGroupId(layers[0]);
            if (layersLinkGroupId != linkGroupId) {
                throw new Exception("layersLinkGroupId and linkGroupId are not equal.");
            }


            Layer[] linkedLayers = psd.getLinkedLayersManager().getLayersByLinkGroupId(linkGroupId);


            for (Layer linkedLayer : linkedLayers) {
                psd.getLinkedLayersManager().unlinkLayer(linkedLayer);
            }


            linkedLayers = psd.getLinkedLayersManager().getLayersByLinkGroupId(linkGroupId);
            if (linkedLayers != null) {
                throw new Exception("The linkedLayers field is not NULL.");
            }
            psd.save(dataDir + "LinkedLayerexample_output.psd");
        } finally {
            psd.dispose();
        }
