Quick how to use:


First you have to choose type of translation (to correct splitting in pieces). You can open a file, copy from clipboard ar manualy write (or speak - Google service) text to translate. Files encoding is autodetected, depends on size of file it loads for a while. Hit the Translate button. Another option is load image and use OCR to get text. (Text can be also read aloud before you start translating process.)


Text is now splitted in pieces so you can start translate - just write the translated text and confirm when translation of piece is done (you can revert this later and also save translation without confirming). If you wanna use Bing button you have to be connected to network and have selected used languages in preferences. The progress bar bottom inform you about status of translation. Navigating between pieces is one by one, also you can jump on next/previous not confirmed one or go to position number. Reload option is for case you want load last saved translation of actual piece. Select Theasaurus option if you want find words in thesaurus (Big Huge Thesaurus(ENG)).


When you are done with translation choose option Show result to get translated text - only confirmed pieces are replaced, rest remains in original language. (Same as for loading files -  it can take a while.


You can save result as text file (in preferences you can choose Windows/Linux end of line), audio file, read aloud (TTS), email it or copy to clipboard. Also you can start new translation.
