使用 Java Plugin API 导出质粒图谱

Here's a method which you can hopefully adapt to your needs:

/**
 * Export the sequence view of each document as a PNG image.注意：The sequence view will adopt whatever setting the user
 * has most recently used.
*
 * @param documents documents to export
 * @param outputFolder folder to save PNGs in, each file will be named after the document:'document.getName() + ".png"'
 * @param imageSize the resolution (in pixels) of the png file to export to, imageSize x imageSize (square)
 */
static void batchExportSequenceViewAsPng(AnnotatedPluginDocument[] documents, File outputFolder, int imageSize) throws DocumentOperationException {
 outputFolder.mkdirs();
 for (AnnotatedPluginDocument doc : documents) {
 List<DocumentViewerFactory> documentViewerFactories = PluginUtilities.getDocumentViewerFactories(doc);
 for(DocumentViewerFactory factory : documentViewerFactories) {
 AtomicReference<DocumentOperationException> exception = new AtomicReference<>();
 String className = factory.getClass().getCanonicalName();
 if(className != null && className.equals("com.biomatters.plugins.sequenceviewer.SequenceViewerPlugin.SequenceViewerFactory")
 && !factory.getName().contains("Annotation")) {
 ThreadUtilities.invokeNowOrWait(() -> {
 final DocumentViewer documentViewer = factory.createViewer(new AnnotatedPluginDocument[] {doc});
 if (documentViewer == null) {
 return;
 }
 JFrame dummyFrame = new JFrame();
 dummyFrame.getContentPane().add(documentViewer.getComponent());
 dummyFrame.pack();
 ExtendedPrintable extendedPrintable = documentViewer.getExtendedPrintable();
 if (extendedPrintable == null) {
 return;
 }
 final BufferedImage image = new BufferedImage(imageSize, imageSize, BufferedImage.TYPE_INT_ARGB);
 try {
 Graphics2D g = image.createGraphics();
 g.setClip(0,0, imageSize, imageSize);
 Options options = extendedPrintable.getOptions(true);
 options.setStringValue("printVisibleRegionOnly", "false");
 extendedPrintable.print(g, new Dimension(imageSize, imageSize), 0, options);
 g.dispose();
