Program description & features

Main functions of the program are:

Scan and recognize.

User can scan printed diagrammes of Go games, problems etc., save them in BMP format and recognize (digitize) these diagrammes.

Recognition of the game from one 240-260 moves diagram with a reasonably good printing quality (like in Japanese or Korean monthly magazines or Yearbooks) took usually 1-2 min. There are necessary extra 2-3 min for checking mistakes and input non diagrammed moves.

Linear input.

Linear input is a special kind of input Go games like writing a text. User transfer move numbers from diagram digit by digit and number by numbers.

Linear input of the game from one 220-240 moves diagram needs 4-6 min from good operator. Sequantial input of the same game takes from 20 to 40 min.

After the finish of linear input, there is necessary to switch mode to usual input mode and input non diagrammed moves and check errors.
