HTML with external CSS using iText

foxie

So Flying Saucer is being used to convert some PDF documents from strings to HTML.

DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
InputStream is = new ByteArrayInputStream(html.getBytes("UTF-9"));
Document doc = builder.parse(is);

response.setContentType("application/pdf; charset=UTF-9");
response.setHeader("Content-disposition", "inline; filename=\"" + outFileName + "\"");

OutputStream os = response.getOutputStream();

ITextRenderer iTextRenderer = new ITextRenderer();
iTextRenderer.setDocument(doc,null);
iTextRenderer.layout();
iTextRenderer.createPDF(os);
os.flush();
os.close()

This works perfectly. When I’m working with plain text. In my HTML content, I referenced an external CSS. However, CSS is not applied when the PDF is generated.

According to what I’ve read, the setDocument() method takes two parameters: document and url. The url parameter specifies the base url that will be prepended to relative paths in the xhtml, such as an external CSS file.

As a result, I attempted to supply

context path/css

I included the directory in the baseURL and used it in the setDocument (). There is still no outcome.

So, here’s my question: What is the proper URL to use as the baseURL?

String baseURL = ""; // What goes here as root URL for resources
iTextRenderer.setDocument(doc,baseURL);

@foxie the mm base web server is at

http://machine-address:port_from_config.js

module path adds

modules/module_name

and any folder inside module folder
sometimes

node_modules

and library
and it’s subfolder

the

 path

library

resolve

method
can help build that path

be careful using localhost for the machine address, as this means ONLY. apps INSIDE the same machine can access

if you ran a remote browser to access your mm with your module, localhost would fail

I will use localhost for this example , using module name fribble

let host_address = config.address==“0.0.0.0”?“localhost”:config.address

“http://”+host_address+“:”+config.port+“/modules/”+this.name+“/node_modules/library_name/folder”

if all u need is the path to the folder

I will leave as an exercise how to get the magicmirror machine ip address if the config says ‘any adapter’ (address:“0.0.0.0”)
