Parsing html to pdf with iText, image base64
提问by jd.carretero
I'm doing a PDF report in which I have to insert some html fragments. I'm done with iText5 and my code is:
我正在做一个 PDF 报告，我必须在其中插入一些 html 片段。我已经完成了 iText5，我的代码是：
Paragraph paragraph = new Paragraph();
HTMLWorker htmlWorker = new HTMLWorker(docPDF);
htmlWorker.parse(new StringReader(...html string in here....));
Everything is working fine but when in the html code there is a tag with the source in base64 like this
一切正常，但是当在 html 代码中有一个像这样在 base64 中带有源代码的标签时
<img alt="" src="data:image/png;base64,iVBORw0KGgoAAAANSUh......" />
it displays the following error:

Here is the java implementation of custom image tag processor:
这是自定义图像标签处理器的java实现：
public static void main(String[] args) {
convertHtmlToPdf();
}
private static void convertHtmlToPdf() {
try {
final OutputStream file = new FileOutputStream(new File("C:\Test.pdf"));
final Document document = new Document();
final PdfWriter writer = PdfWriter.getInstance(document, file);
document.open();
final TagProcessorFactory tagProcessorFactory = Tags.getHtmlTagProcessorFactory();
tagProcessorFactory.removeProcessor(HTML.Tag.IMG);
tagProcessorFactory.addProcessor(new ImageTagProcessor(), HTML.Tag.IMG);
final CssFilesImpl cssFiles = new CssFilesImpl();
cssFiles.add(XMLWorkerHelper.getInstance().getDefaultCSS());
final StyleAttrCSSResolver cssResolver = new StyleAttrCSSResolver(cssFiles);
final HtmlPipelineContext hpc = new HtmlPipelineContext(new CssAppliersImpl(new XMLWorkerFontProvider()));
hpc.setAcceptUnknown(true).autoBookmark(true).setTagFactory(tagProcessorFactory);
final HtmlPipeline htmlPipeline = new HtmlPipeline(hpc, new PdfWriterPipeline(document, writer));
final Pipeline<?> pipeline = new CssResolverPipeline(cssResolver, htmlPipeline);
final XMLWorker worker = new XMLWorker(pipeline, true);
final Charset charset = Charset.forName("UTF-8");
final XMLParser xmlParser = new XMLParser(true, worker, charset);
final InputStream is = new FileInputStream("C:\test.html");
xmlParser.parse(is, charset);
is.close();
document.close();
file.close();
} catch (Exception e) {
e.printStackTrace();
// TODO
}
}

It's possible to replace the built-in tags processors of iText(Sharp). Here is the C# code with custom image tag processor which supports base64 images too. It's easy to convert it to java (base libraries iText and iTextSharp have the same API).
可以替换 iText (Sharp) 的内置标签处理器。这是带有自定义图像标记处理器的 C# 代码，它也支持 base64 图像。很容易将其转换为 java（基础库 iText 和 iTextSharp 具有相同的 API）。
if(src.startsWith("data:image/png;base64")){
final String base64Data = src.substring(src.indexOf(",") + 1);
try {
img = Image.getInstance(Base64.decode(base64Data));
} catch (Exception e) {
throw new ExceptionConverter(e);
}
}

the solution provided by Ajay Deshwal is a very good reference point to work on .png Base64 images in iText.
Ajay Deshwal 提供的解决方案是在 iText 中处理 .png Base64 图像的一个很好的参考点。
all i did was to goto my HTMLWOrker and edit the method startElement(String tag, HashMap h);
我所做的只是转到我的 HTMLWOrker 并编辑方法 startElement (String tag, HashMap h);
at this section of the method, if (tag.equals(HtmlTags.IMAGE)), blahblah.. just add anther check
在方法的这一部分，如果 (tag.equals (HtmlTags.IMAGE)), blahblah .. 只需添加花药检查

Add the below width and height of the image in the above code of Ajay Deshwal which is working perfectly for me.
在 Ajay Deshwal 的上述代码中添加以下图像的宽度和高度，这对我来说非常合适。
