How to improve accuracy
Can i OCR a portion of an image by command line?
The -s option is only for screen captures. I may add a crop option in the future though. In the meantime, try using something like ImageMagick to crop the images before passing them to Capture2Text.
Command Line with AHK
Example: TempFile := A_Temp . "\temp_capture.txt" FileDelete, %TempFile% RunWait, Capture2Text_CLI.exe -d -s "0 0 600 600" -o %TempFile%,,Hide FileRead, CaptureText, %TempFile% FileDelete, %TempFile% MsgBox %CaptureText%
support google translate
This feature is already supported. Check out the following link from the documentation for details: http://capture2text.sourceforge.net/#translation
I can't imagine a lot of people using this feature. Perhaps your application can just use the CLI instead.
