HTML -- Image (in the background)

Question

Hi All,
I want to be able to create an image from an HTML file. I am thinking about writing my own FAX library and need to send G3 images (JAI - JCA). Can anyone point me in the right direction? I do not want to do a screen shot since that would require showing the HTML on the screen. I would like to be able to convert the HTML to a G3 TIFF in the background.
Thanks in advance,

Answer 1

I am trying to save as a JPEG to begin with... This is my code and I'm having problems. Anyone have any ideas? It is dying on the je.encode(bi) line. Also, for some reason, if I uncomment the commented out lines, it hangs. Any ideas on that one too?

               GenerateHTMLBufferedImage(new File(htmlFile), bi);
               FileOutputStream fos = new FileOutputStream(jpegFile);
               JPEGEncodeParam jp = new JPEGEncodeParam();
               ImageEncoder je = ImageCodec.createImageEncoder("JPEG", fos, jp);

          return true;
}Called from other code
HTMLPageToImageConverter.SaveHTMLFileToJPEG("d:/page1.html", "d:/page1.jpeg");
...Thanks in advence,
