当从Java剪贴板对象检索为图像时，outlook中的剪贴板副本始终具有黑色背景设置 [英] Clipboard copy from outlook always has black background set when retrieved as image from Java clipboard object

问题描述

以下是申请步骤

1. 从html电子邮件或网站复制一些richtext（文本+图像的组合）


2. 在您的java代码中检索从剪贴板对象复制的内容为BufferredImage


3. 将检索到的图像对象保存为磁盘上的图像文件

您会注意到，在保存的文件中，图像正常，任何非黑色文本都显示正常，但黑色背景中的黑色文字似乎丢失。找不到覆盖生成图像的黑色背景的方法。下面是一些示例代码。

You'll notice that in the saved file, the image comes fine, any non-black text appears fine but black text seems lost in the black background. Could not find a way to override the black background for the generated image. Some example code below.

     BufferedImage image = null;
try {
     image = (BufferedImage) transferable.getTransferData(DataFlavor.imageFlavor);

} catch (UnsupportedFlavorException e) {
     // TODO Auto-generated catch block
     e.printStackTrace();
      } catch (IOException e) {
     // TODO Auto-generated catch block
     e.printStackTrace();
}

saveImageToDisk(image);

      private void saveImageToDisk(BufferedImage image) {
    File outputFile = new File("c:\\image.png");
    try {
        ImageIO.write(image, "png", outputFile);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

找到解决方案 - 它是使用自定义系统风格，它可以理解'image \ x-emf'的mimetype。剥离前8个字节并将剩余内容写为Bufferred图像

Found the solution - it is to use a custom system flavour which understands the mimetype of 'image\x-emf'. strip first 8 bytes and write the remaining content as Bufferred image
