        document.open();
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        screen.compress(Bitmap.CompressFormat.JPEG, 100, stream);

Answer 1

You can create your document like this:

Document pdfDoc = new Document(PageSize.A4, 0f, 0f, 0f, 0f);

if you want your page rotated to landscape you can add .Rotate() after .A4 If max height of content is reached iText will create the new page.

Have a look at this answer https://stackoverflow.com/a/11206227/5840866 on a similar question about the page number at the end of the page. You can also use PdfPageEventHelper
