Conversione di una cella della tabella delle parole Ms nell'immagine utilizzando java

Question

Devo convertire ogni cella della tabella delle parole ms in immagini. Ho codice di scrittura per getImage e getText ma voglio unirli entrambi e convertirli in immagine singola, quindi voglio solo convertire la cella nell'immagine.

Reference

XWPFDocument doc = new XWPFDocument(new FileInputStream(fileName)); 
     List<XWPFTable> table = doc.getTables(); 
     for (XWPFTable xwpfTable : table) { 
      List<XWPFTableRow> row = xwpfTable.getRows(); 
      for (XWPFTableRow xwpfTableRow : row) { 
       List<XWPFTableCell> cell = xwpfTableRow.getTableCells(); 
       for (XWPFTableCell xwpfTableCell : cell) { 
        if (xwpfTableCell != null) { 
         System.out.println(xwpfTableCell.getText()); 
         String s = xwpfTableCell.getText(); 
         for (XWPFParagraph p : xwpfTableCell.getParagraphs()) { 
          for (XWPFRun run : p.getRuns()) { 
           for (XWPFPicture pic : run.getEmbeddedPictures()) { 
            byte[] pictureData = pic.getPictureData().getData(); 
            System.out.println("picture : " + pictureData); 
           } 
          } 
         } 
        } 
       } 
      } 
     }

ho avuto la soluzione di questo problema, è possibile ottenere utilizzando la libreria Java Aspose-parola .. Metodo principale

public static void main(String[] args) throws Exception { 
    // The path to the documents directory. 
    String dataDir = "D://test//"; 

    // Load the documents which store the shapes we want to render. 
    Document doc = new Document(dataDir + "TestFile.doc"); 

    // Retrieve the target shape from the document. In our sample document 
    // this is the first shape. 

    RenderCellToImage(dataDir, doc); 
} 

// RenderCellToImage

public static void RenderCellToImage(String dataDir, Document doc) 
     throws Exception { 

     Cell cell = (Cell) doc.getChild(NodeType.CELL, 0, true); 
     RenderNode(cell, dataDir + "TestFile.RenderCell".png", 
       null); 
     System.out.println("Cell rendered to image__successfully."); 

    } 
} 
    ///<summary> 
///Renders any node in a document to the path specified using the image 
// save options. 
///</summary> 
///<param name="node">The node to render.</param> 
///<param name="path">The path to save the rendered image to.</param> 
///<param name="imageOptions">The image options to use during rendering. 
// This can be null.</param> 
public static void RenderNode(Node node, String filePath, 
     ImageSaveOptions imageOptions) throws Exception { 
    // Run some argument checks. 
    if (node == null) 
     throw new IllegalArgumentException("Node cannot be null"); 

    // If no image options are supplied, create default options. 
    if (imageOptions == null) 
     imageOptions = new ImageSaveOptions(FileFormatUtil.extensionToSaveFormat((filePath.split("\\.")[filePath 
         .split("\\.").length - 1]))); 

    // Store the paper color to be used on the final image and change to 
    // transparent. 
    // This will cause any content around the rendered node to be removed 
    // later on. 
    Color savePaperColor = imageOptions.getPaperColor(); 
    // imageOptions.PaperColor = Color.Transparent; 
    imageOptions.setPaperColor(new Color(0, 0, 0, 0)); 
    // There a bug which affects the cache of a cloned node. To avoid this 
    // we instead clone the entire document including all nodes, 
    // find the matching node in the cloned document and render that 
    // instead. 
    Document doc = (Document) node.getDocument().deepClone(true); 
    node = doc.getChild(NodeType.ANY,node.getDocument().getChildNodes(NodeType.ANY, true).indexOf(node), true); 

    // Create a temporary shape to store the target node in. This shape will 
    // be rendered to retrieve 
    // the rendered content of the node. 
    Shape shape = new Shape(doc, ShapeType.TEXT_BOX); 

    Section parentSection = (Section) node.getAncestor(NodeType.SECTION); 

    // Assume that the node cannot be larger than the page in size. 
    shape.setWidth(parentSection.getPageSetup().getPageWidth()); 
    shape.setHeight(parentSection.getPageSetup().getPageHeight()); 
    shape.setFillColor(new Color(0, 0, 0, 0)); // We must make the shape and 
               // paper color transparent. 

    // Don't draw a surrounding line on the shape. 
    shape.setStroked(false); 

    // Move up through the DOM until we find node which is suitable to 
    // insert into a Shape (a node with a parent can contain paragraph, 
    // tables the same as a shape). 
    // Each parent node is cloned on the way up so even a descendant node 
    // passed to this method can be rendered. 
    // Since we are working with the actual nodes of the document we need to 
    // clone the target node into the temporary shape. 
    Node currentNode = node; 
    while (!(currentNode.getParentNode() instanceof InlineStory 
      || currentNode.getParentNode() instanceof Story || currentNode 
       .getParentNode() instanceof ShapeBase)) { 
     CompositeNode parent = (CompositeNode) currentNode.getParentNode() 
       .deepClone(false); 
     currentNode = currentNode.getParentNode(); 
     parent.appendChild(node.deepClone(true)); 
     node = parent; // Store this new node to be inserted into the shape. 
    } 

    // We must add the shape to the document tree to have it rendered. 
    shape.appendChild(node.deepClone(true)); 
    parentSection.getBody().getFirstParagraph().appendChild(shape); 

    // Render the shape to stream so we can take advantage of the effects of 
    // the ImageSaveOptions class. 
    // Retrieve the rendered image and remove the shape from the document. 
    ByteArrayOutputStream stream = new ByteArrayOutputStream(); 
    shape.getShapeRenderer().save(stream, imageOptions); 
    shape.remove(); 

    // Load the image into a new bitmap. 
    BufferedImage renderedImage = ImageIO.read(new ByteArrayInputStream(
      stream.toByteArray())); 

    // Extract the actual content of the image by cropping transparent space 
    // around 
    // the rendered shape. 
    Rectangle cropRectangle = FindBoundingBoxAroundNode(renderedImage); 

    BufferedImage croppedImage = new BufferedImage(cropRectangle.width, 
      cropRectangle.height, BufferedImage.TYPE_INT_RGB); 

    // Create the final image with the proper background color. 
    Graphics2D g = croppedImage.createGraphics(); 
    g.setBackground(savePaperColor); 
    g.clearRect(0, 0, croppedImage.getWidth(), croppedImage.getHeight()); 

    g.drawImage(renderedImage, 0, 0, croppedImage.getWidth(), 
      croppedImage.getHeight(), cropRectangle.x, cropRectangle.y, 
      cropRectangle.x + cropRectangle.width, cropRectangle.y 
        + cropRectangle.height, null); 




    ImageIO.write(croppedImage, "png", new File(filePath));
