添加图像docx4j为doc文件 [英] Adding image with docx4j to doc file

问题描述

我试图使用docx4j库中的Andr​​oid的图像添加到的docx文件。
我面对一个例外：

I'm trying to add an image to a docx file using docx4j library within Android.
I've faced to an exception:

E/AndroidRuntime(21818): java.lang.ExceptionInInitializerError
E/AndroidRuntime(21818):    at org.apache.xmlgraphics.image.loader.impl.AbstractImageSessionContext.newSource(AbstractImageSessionContext.java:134)

                                ...

这是指该code：

It is referring to this code:

WordprocessingMLPackage wordMLPackage;
File file;
...
BinaryPartAbstractImage imagePart = BinaryPartAbstractImage.createImagePart(wordMLPackage, file);

我已经添加从 AndroidDocxToHtml 的例子中，所有必要的库（和 AE-awt.jar 太）为库文件夹我的应用程序。
没有照片我的应用程序完全产生的docx文件。

有什么办法解决呢？
谢谢！

I've already added all necessary libraries from AndroidDocxToHtml example (and ae-awt.jar too) to libs folder of my app.
Without images my app generates docx files perfectly.

Is there any way to solve it?
Thanks!

推荐答案

对于每个人，谁遇到这个问题了。

For everyone, who faced this problem too.

下面是必要的步骤，使docx4j正常工作与图片：

Here are necessary steps to make docx4j works fine with images:

1. 添加缺课从OpenJDK的拨出与包AE 。
2. 更改引用新的类，例如 sun.awt.AppContext 到 ae.sun.awt.AppContext

3. 在 org.apache.xmlgraphics.util.Service 手工填写列表preloaders：

1. Add missed classes from OpenJDK to appropriate packages with ae.
2. Change references to new classes, for example sun.awt.AppContext to ae.sun.awt.AppContext.

3. In org.apache.xmlgraphics.util.Service manually fill list with preloaders:

private static List<String> getProviderNames(Class<?> cls, ClassLoader cl) {
    ...
    if (fillDefautsProviderNames(cls, l))
        return l;
    ...
}

private static boolean fillDefautsProviderNames(Class<?> cls, List<String> l) {
    if (cls == org.apache.xmlgraphics.image.loader.spi.ImagePreloader.class) {
        l.add("org.apache.xmlgraphics.image.loader.impl.PreloaderTIFF");
        l.add("org.apache.xmlgraphics.image.loader.impl.PreloaderGIF");
        l.add("org.apache.xmlgraphics.image.loader.impl.PreloaderJPEG");
        l.add("org.apache.xmlgraphics.image.loader.impl.PreloaderBMP");
        l.add("org.apache.xmlgraphics.image.loader.impl.PreloaderEMF");
        l.add("org.apache.xmlgraphics.image.loader.impl.PreloaderEPS");
        l.add("org.apache.xmlgraphics.image.loader.impl.imageio.PreloaderImageIO");
        return true;
    }
    return false;
}

删除功能 displayImageInfo（的imageinfo信息）在 org.docx4j.openpackaging.parts.Wordpro​​cessingML.BinaryPartAbstractImage 。

我有prepared仓库的变化： AE-AWT ，的 AE-xmlgraphics-公共，的 docx4j-的Andr​​oid 。

I've prepared repositories with changes: ae-awt, ae-xmlgraphics-commons, docx4j-android.

您可以在这里找到编译库： docx4j_images_ prepared_libs.zip

You can find compiled libs here: docx4j_images_prepared_libs.zip
