PDF is mainly used for layout and fixes the page size; epub is a stream format, which is similar to the html page. Therefore, converting pdf into epub is not an easy task (e.g. paragraph detection, multi-column processing, and the conversion of tables, mathematical formulas, and charts). The general converter can just convert pdf rigidly, so the format becomes a mess. For slightly more complex documents, almost all cannot be read after conversion. The software provides a powerful and easy-to-use function to handle complex pdf documents and to maintain the "original flavour" of documentation as much as possible."; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
