"Fit to page width" using Java ITextRenderer html2pdf conversion

We generate a html page as Java String and convert it to pdf using ITextRenderer. The generated pdf is in vector mode, we would like to scale it to fit a certain page widht (A4 paper). We want to keep the vector representation. We need such code, it should use free libraries or necessary code should be included as deliverable. Requirements: - The solution cannot be a css tweak because it must be dynamic independent of given page content and styles - The implementation must be in Java. You will need to hack into Itextrenderer etc. - Width must squeeze to fit A4 width, length is not important (preserve scale/proportionality of width x height), it will print as many pages as necessary split by A4 height. Current code is: /** * Convert HTML to PDF * @param in HTML * @param out PDF */ public static void html2pdf(InputStream in, OutputStream out) { try { StringWriter sw = new StringWriter(); Tidy tidier = new Tidy(); { [login to view URL](ENCODING); [login to view URL](true); [login to view URL](true); [login to view URL](true); [login to view URL](false); [login to view URL](false); [login to view URL](in, sw); [login to view URL](); } { ITextRenderer renderer = new ITextRenderer(); [login to view URL]([login to view URL]().toString()); [login to view URL](); [login to view URL](out); } } catch (Throwable e) { throw new RuntimeException(e); } }
