I am having an issue to parse an image within HTML structure to a PDF file, I have tried using the following line to gather the image , however the PDF file is being created without the image. I am using iText with xmlworker libraries, the html is all stored in a string then parsed into an input stream as shown below in code.

.....
<img class='top' src='file:///android_res/drawable/logo.png' height='100px' width='200px'/>
........
........
InputStream is = new ByteArrayInputStream(str.getBytes()); //contains the html string
XMLWorkerHelper.getInstance().parseXHtml(writer, document, is);

您可能应该使用自己的 ImageProvider 来获取图像。( http://api.itextpdf.com/xml/com/itextpdf/tool/xml/pipeline/html/ImageProvider.html )

这个接口有4个方法：

  • 获取图像根路径（）
  • 重置（）
  • 检索（字符串源）
  • 存储（字符串 src，图像 img）

您需要实现检索方法以从文件系统返回图像。
