You can compare a translated PDF side-by-side with the original PDF. 
Comparing this way is only available for a PDF translated via TransPDF. For general document comparison see Side-by-side comparisons

To compare your translated PDF to the original:

  1. Open a translated PDF.
    This can either be a preview PDF generated earlier (which will be read-only), or a final translated PDF you purchased already.
  2. Choose a comparison mode and Infix Pro PDF Editor will download the original PDF from TransPDF
    • Translate->Compare Vertical or press Compare Horizontal tool icon on the Translation toolbar (View->Toolbars->Translation) 
      Infix Example Screenshot - compare horizontal
      In vertical mode, the translated PDF is at the bottom of the window.
    • Translate->Compare Horizontal or press Compare Vertical tool icon on the Translation toolbar (View->Toolbars->Translation)
      Infix Example Screenshot - compare vertical
      In horizontal mode, the translated PDF is on the right-hand-side of the screen.

  1. Both documents will keep in-step with each other as you scroll around and zoom. 
  2. Only a final PDF you have purchased may be edited in this mode.

Exiting comparison mode

To exit comparison mode, choose the current comparison mode menu item again. 
For example, if you are in Compare Horizontal mode, choose Translate->Compare Horizontal again.
