Constructor Detail

HtmlResourceResolver

public HtmlResourceResolver(String baseUri,
                            ProcessorContext context)

Creates a new HtmlResourceResolver instance. If baseUri is a string that represents an absolute URI with any schema except "file" - resources url values will be resolved exactly as "new URL(baseUrl, uriString)". Otherwise base URI will be handled as path in local file system.

If empty string or relative URI string is passed as base URI, then it will be resolved against current working directory of this application instance.

Parameters:

baseUri - base URI against which all relative resource URIs will be resolved

context - ProcessorContext instance for the current HTML to PDF conversion process
