OpenOffice API：將Impress（演示文稿）文件保存爲自包含文件

Question

當我使用'MS PowerPoint 97'過濾器保存文件時，GraphicObjectShape對象中使用的圖像文件只是鏈接的，不包含在文件中。

是否有此過濾器的屬性或文檔屬性使OOo創建自包含文件（嵌入圖像文件而不是鏈接）？

編輯：

的XLinkageSupport對象具有breakLink功能。任何線索如何獲得這些接口？

您可以通過com.sun.star.drawing.BitmapTable對象將圖像嵌入到OOo文檔中。下面的函數將把文檔（它的XMultiServiceFactory接口），一個File對象指向你選擇的圖像文件和一個必須唯一的internalName，嵌入圖像並返回指向嵌入實例的URL。

/** 
* Embeds an image into the document and gets back the new URL. 
* 
* @param factory Factory interface of the document. 
* @param file Image file. 
* @param internalName Name of the image used inside the document. 
* @return URL of the embedded image. 
*/ 
public static String embedLocalImage(XMultiServiceFactory factory, File localFile, String internalName) { 

    // future return value 
    String newURL = null; 

    // URL of the file (note that BitmapTable expects URLs starting with 
    // "file://" rather than just "file:". Also note that getRawPath() will 
    // return an encoded URL (with special character in the form of %xx). 
    String imageURL = "file://" + localFile.toURI().getRawPath(); 

    try { 

     // get a BitmapTable object from the document (and get interface) 
     Object bitmapTable = factory.createInstance("com.sun.star.drawing.BitmapTable"); 
     XNameContainer bitmapContainer = (XNameContainer)UnoRuntime.queryInterface(XNameContainer.class, bitmapTable); 

     // insert image by URL into the table 
     bitmapContainer.insertByName(internalName, imageURL); 

     // get interface 
     XNameAccess bitmapAccess = (XNameAccess)UnoRuntime.queryInterface(XNameAccess.class, bitmapTable); 

     // get the embedded URL back 
     newURL = (String)bitmapAccess.getByName(internalName); 

    } catch (Exception e) { 
     throw new RuntimeException(e); 
    } 

    // return the new (embedded) url 
    return newURL; 
}
