Hey. I want to auto crop/trim the attached image. An image for every kanji character should be the solution. thanks for the help.

Unless every pixel is identical for each character, this will be very difficult. If you are in luck, you can simply look for completely white rows to separate the characters.

It looks like there is kerning involved, so looking for white columns won't solve the problem.
