我需要的Apache POI图片从Word文档转换为HTML文件 [英] I need Apache POI Pictures converted from a word document to a html file
问题描述
我有一个使用了Java的Apache POI库中打开一个Word文档，并将其转换为HTML，使用Apache的POI一些code和它也得到对文档图像的字节数组数据。但我需要这些信息转换为HTML写出来到HTML文件。任何提示或建议将是AP preciated。请记住，我是一个桌面开发开发商，而不是一个网络程序员，所以当你提出建议，请记住这一点。下面的code获取图像。
私人无效parseWordText（档案文件）抛出IOException
的FileInputStream FS =新的FileInputStream（文件）;
DOC =新HWPFDocument（FS）;
PicturesTable picTable = doc.getPicturesTable（）;
如果（picTable！= NULL）{
picList =新的ArrayList＆LT;图片和GT;（picTable.getAllPictures（））;
如果（！picList.isEmpty（））{
对于（图片图：picList）{
字节[]的字节数组= pic.getContent（）;
pic.suggestFileExtension（）;
pic.suggestFullFileName（）;
pic.suggestPictureType（）;
pic.getStartOffset（）;
}
}
}
然后就是下code转换为HTML文档。有没有一种办法的ByteArray添加到ByteArrayOutputStream下code？
私人无效convertWordDoctoHTML（档案文件）抛出的ParserConfigurationException，TransformerConfigurationException，TransformerException中，IOException异常{
HWPFDocumentCore wordDocument = NULL;
尝试{
wordDocument = WordToHtmlUtils.loadDoc（新的FileInputStream（文件））;
}赶上（IOException异常前）{
Exceptions.printStackTrace（除息）;
} WordToHtmlConverter wordToHtmlConverter =新WordToHtmlConverter（DocumentBuilderFactory.newInstance（）newDocumentBuilder（）新建文档（））;
wordToHtmlConverter.processDocument（wordDocument）;
org.w3c.dom.Document中的HTMLDocument = wordToHtmlConverter.getDocument（）;
NamedNodeMap中的节点= htmlDocument.getAttributes（）;
ByteArrayOutputStream出=新ByteArrayOutputStream（）;
DOMSource的DOMSource的=新DOMSource的（HTMLDocument的）;
StreamResult streamResult =新的StreamResult（出）; TF的TransformerFactory = TransformerFactory.newInstance（）;
变压器串行= tf.newTransformer（）;
serializer.setOutputProperty（OutputKeys.ENCODING，UTF-8）;
serializer.setOutputProperty（OutputKeys.INDENT，是）;
serializer.setOutputProperty（OutputKeys.METHOD，HTML）;
serializer.transform（DOMSource的，streamResult）;
out.close（）; 字符串结果=新的String（out.toByteArray（））;
acDocTextArea.setText（newDocText）; 的htmlText =结果;}

它在JavaDoc规定：
的此实现不创建图像或链接到他们。这可以是
通过重写改变{@link #processImage（元素，布尔，图片）}方法的
如果你看看那个 processImage来（...）方法AbstractWordConverter.java在行790，它看起来像方法正在调用然后命名为另一种方法 processImageWithoutPicturesManager（...）。

这种方法在 WordToHtmlConverter 定义再次和详细的可疑看起来像你想要增加你的code（317线）的地方：
@覆盖
保护无效processImageWithoutPicturesManager（元currentBlock，
布尔内联，画中画）
{
//没有默认的实现 - 跳
currentBlock.appendChild（htmlDocumentFacade.document
.createComment（图像链接'
+ picture.suggestFullFileName（）+可以在这里））;
}
我觉得你的地步，启动图像插入流。
创建转换器的一个子类，例如，搜索
公共类InlineImageWordToHtmlConverter扩展WordToHtmlConverter
然后重写方法和地点的任何code进去。

我没有测试它，但它应该是从我所看到的理论上的正确方式。
I have some code that uses the Java Apache POI library to open a Microsoft word document and convert it to html, using the the Apache POI and it also gets the byte array data of images on the document. But I need to convert this information to html to write out to an html file. Any hints or suggestions would be appreciated. Keep in mind that I am a desktop dev developer and not a web programmer, so when you make suggestions, please remember that. The code below gets the image.
private void parseWordText(File file) throws IOException {
FileInputStream fs = new FileInputStream(file);
doc = new HWPFDocument(fs);
PicturesTable picTable = doc.getPicturesTable();
if (picTable != null){
picList = new ArrayList<Picture>(picTable.getAllPictures());
if (!picList.isEmpty()) {
for (Picture pic : picList) {
byte[] byteArray = pic.getContent();
pic.suggestFileExtension();
pic.suggestFullFileName();
pic.suggestPictureType();
pic.getStartOffset();
}
}
}
Then the code below this converts the document to html. Is there a way to add the byteArray to the ByteArrayOutputStream in the code below?
private void convertWordDoctoHTML(File file) throws ParserConfigurationException, TransformerConfigurationException, TransformerException, IOException {
HWPFDocumentCore wordDocument = null;
try {
wordDocument = WordToHtmlUtils.loadDoc(new FileInputStream(file));
} catch (IOException ex) {
Exceptions.printStackTrace(ex);
}
WordToHtmlConverter wordToHtmlConverter = new WordToHtmlConverter(DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument());
wordToHtmlConverter.processDocument(wordDocument);
org.w3c.dom.Document htmlDocument = wordToHtmlConverter.getDocument();
NamedNodeMap node = htmlDocument.getAttributes();
ByteArrayOutputStream out = new ByteArrayOutputStream();
DOMSource domSource = new DOMSource(htmlDocument);
StreamResult streamResult = new StreamResult(out);
TransformerFactory tf = TransformerFactory.newInstance();
Transformer serializer = tf.newTransformer();
serializer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
serializer.setOutputProperty(OutputKeys.INDENT, "yes");
serializer.setOutputProperty(OutputKeys.METHOD, "html");
serializer.transform(domSource, streamResult);
out.close();
String result = new String(out.toByteArray());
acDocTextArea.setText(newDocText);
htmlText = result;
}
Looking at the source code for the org.apache.poi.hwpf.converter.WordToHtmlConverter at
http://svn.apache.org/viewvc/poi/trunk/src/scratchpad/src/org/apache/poi/hwpf/converter/WordToHtmlConverter.java?view=markup&pathrev=1180740
It states in the JavaDoc:
This implementation doesn't create images or links to them. This can be changed by overriding {@link #processImage(Element, boolean, Picture)} method
If you take a look at that processImage(...) method in AbstractWordConverter.java at line 790, it looks like the method is calling then another method named processImageWithoutPicturesManager(...).
http://svn.apache.org/viewvc/poi/trunk/src/scratchpad/src/org/apache/poi/hwpf/converter/AbstractWordConverter.java?view=markup&pathrev=1180740
This method is defined in WordToHtmlConverter again and looks suspiciously exact like the place you want to grow your code (line 317):
@Override
protected void processImageWithoutPicturesManager(Element currentBlock,
boolean inlined, Picture picture)
{
// no default implementation -- skip
currentBlock.appendChild(htmlDocumentFacade.document
.createComment("Image link to '"
+ picture.suggestFullFileName() + "' can be here"));
}
I think you have the point where to start inserting the images into the flow.
Create a subclass of the converter, e.g.
public class InlineImageWordToHtmlConverter extends WordToHtmlConverter
and then override the method and place whatever code into it.
I haven't tested it, but it should be the right way from what I see theoretically.
