Question

我正在尝试使用java程序控制simpress演示文稿。我可以得到我的演示文稿的下一个效果，但只有当它不是全屏时。如果我将我的PropertyValue“IsFullScreen”设置为“TRUE”，我的presentation.isRunning（）将返回false，并且我的xSlideShowController为null。

   public static void lancerPresentation(String url) throws IndexOutOfBoundsException, com.sun.star.io.IOException, InterruptedException{
    //We open the file "~/Documents/testUno.odp"
    XComponent xComponent=null;
    XPresentation2 presentation2 =null;
    try {
        // get the remote office component context
        XComponentContext xContext = com.sun.star.comp.helper.Bootstrap.bootstrap();
        xComponent = openPresentation(xContext, url);
        XPresentationSupplier presentationSupplier = UnoRuntime.queryInterface(XPresentationSupplier.class, xComponent);
        XPresentation presentation = presentationSupplier.getPresentation();
        presentation2 = UnoRuntime.queryInterface(XPresentation2.class, presentation);
        PropertyValue[] aPresentationArgs = new PropertyValue[3];

            aPresentationArgs[0] = new PropertyValue();
            aPresentationArgs[0].Name = "IsAlwaysOnTop";
            aPresentationArgs[0].Value = Boolean.TRUE;

            aPresentationArgs[1] = new PropertyValue();
            aPresentationArgs[1].Name = "IsFullScreen";
            aPresentationArgs[1].Value = Boolean.TRUE;

            aPresentationArgs[2] = new PropertyValue();
            aPresentationArgs[2].Name = "IsAutomatic";
            aPresentationArgs[2].Value = Boolean.TRUE;


        presentation2.startWithArguments(aPresentationArgs);
        System.out.println(presentation2.isRunning()); ==> False
        if(presentation2==null)System.out.println("presentation2 null");



    }
    catch( Exception e) {
        e.printStackTrace(System.err);
        System.exit(1);
    }

   if (presentation2.isRunning()) {
       xSlideShowController = presentation2.getController();
       if(xSlideShowController==null)System.out.println("xSlideShowController null"); ==> Null
   }

我想在下一张幻灯片中保存一个文件。我试过这个，但我的XStorable是空的。

xSlideShowController.gotoFirstSlide();
   XDrawPage slidePreview = xSlideShowController.getSlideByIndex(xSlideShowController.getCurrentSlideIndex()+1);

   if(slidePreview==null)System.out.println("slidePreview null");
   String filePath = "home/bastien/Documents/slideshowtest.jpg";
       PropertyValue[] aStoreProperties = new PropertyValue[2];
       aStoreProperties[0] = new PropertyValue();
       aStoreProperties[1] = new PropertyValue();
       aStoreProperties[0].Name = "Override";
       aStoreProperties[0].Value = true;
       aStoreProperties[1].Name = "FilterName";
       aStoreProperties[1].Value = "slideshowtest";
       XComponent previewComponent =UnoRuntime.queryInterface(
                       XComponent.class, slidePreview);
       if(previewComponent==null)System.out.println("previewComponent null");
       XStorable xStorable = (XStorable) UnoRuntime.queryInterface(
                       XStorable.class, previewComponent);
       if(xStorable==null)System.out.println("xStorable null"); ==> Null
       xStorable.storeAsURL(filePath, aStoreProperties);

我试过了，但XStorable也是空的。

XStorable xStorable = (XStorable)     
UnoRuntime.queryInterface(XStorable.class, slidePreview);

好的，我发现如何将下一张幻灯片保存为图片：

public static boolean save(String fileName) throws IndexOutOfBoundsException, IOException, com.sun.star.uno.Exception {
    if(xSlideShowController.getCurrentSlideIndex() + 1>xSlideShowController.getSlideCount())return false;
    XDrawPage slidePreview = xSlideShowController.getSlideByIndex(xSlideShowController.getCurrentSlideIndex() + 1);
    java.io.File sourceFile = new java.io.File(fileName);
    if(sourceFile.createNewFile())return false;
    StringBuffer sTemplateFileUrl = new StringBuffer("file:///");
    sTemplateFileUrl.append(sourceFile.getCanonicalPath().replace('\\', '/'));
    PropertyValue aFilterData_thumb[] = new PropertyValue[2];
    aFilterData_thumb[0] = new PropertyValue();
    aFilterData_thumb[0].Name = "PixelWidth";
    aFilterData_thumb[0].Value = 1241;

    aFilterData_thumb[1] = new PropertyValue();
    aFilterData_thumb[1].Name = "PixelHeight";
    aFilterData_thumb[1].Value = 1753;

    PropertyValue aProps_thumb[] = new PropertyValue[3];
    aProps_thumb[0] = new PropertyValue();
    aProps_thumb[0].Name = "MediaType";
    aProps_thumb[0].Value = "image/jpeg";

    aProps_thumb[1] = new PropertyValue();
    aProps_thumb[1].Name = "URL";
    aProps_thumb[1].Value = sTemplateFileUrl.toString();

    aProps_thumb[2] = new PropertyValue();
    aProps_thumb[2].Name = "FilterData";
    aProps_thumb[2].Value = aFilterData_thumb;

    XComponent xComp = UnoRuntime.queryInterface(XComponent.class, slidePreview);
    XMultiComponentFactory xMCF
            = xContext.getServiceManager();
    Object exportFilter = xMCF.createInstanceWithContext("com.sun.star.drawing.GraphicExportFilter", xContext);
    XExporter xExporter = UnoRuntime.queryInterface(XExporter.class, exportFilter);
    xExporter.setSourceDocument(xComp);
    XFilter xFilter = UnoRuntime.queryInterface(XFilter.class, xExporter);
    xFilter.filter(aProps_thumb);
    return true;

}

保存XDrawPage，获取全屏演示文稿
