Aspose.Words shape.remove()不完全有效

Question

我想要将图像替换为文本，但当我删除形状节点时，结果是一些图片没有被删除。为什么？

    public void replaceImageToMark() throws Exception {
    Document doc = new Document("D:\\company\\demo.docx");
    NodeCollection shapeCollection = doc.getChildNodes(NodeType.DRAWING_ML, true);
    for (int i = 0; i < shapeCollection.getCount(); i++) {
        DrawingML drawingML = (DrawingML) shapeCollection.get(i);
        if (drawingML.hasImage()) {
            String imageFileName = java.text.MessageFormat.format(
                    "Image.ExportImages.{0} Out{1}", i, FileFormatUtil.imageTypeToExtension(drawingML.getImageData().getImageType()));
            DrawingMLImageData imageData = drawingML.getImageData();
            imageData.save("D:\\company\\pic\\" + imageFileName);
            DocumentBuilder builder = new DocumentBuilder(doc);
            builder.moveTo(drawingML);
            builder.write("${image}");
            drawingML.remove(); // There are some images that are not effective
        }
    }
    doc.save("D:\\company\\newDemo.docx");
}

您正在使用旧版本的Aspose.Words。我建议您使用最新版本的Aspose.Words for Java 18.4。请将代码中的DrawingML替换为Shape，如下所示，以获得所需的输出。

Document doc = new Document(MyDir + "in.docx");

NodeCollection shapeCollection = doc.getChildNodes(NodeType.SHAPE, true);
for (int i = 0; i < shapeCollection.getCount(); i++) {
    Shape shape = (Shape) shapeCollection.get(i);
    if (shape.hasImage()) {
        String imageFileName = java.text.MessageFormat.format(
                "Image.ExportImages.{0} Out{1}", i, FileFormatUtil.imageTypeToExtension(shape.getImageData().getImageType()));
        shape.getImageData().save("D:\\company\\pic\\" + imageFileName);
        DocumentBuilder builder = new DocumentBuilder(doc);
        builder.moveTo(shape);
        builder.write("${image}");
        shape.remove();  
    }
}
doc.save(MyDir + "output.docx");
