changing picture black and white
Dear all,

I want to put a picture to glass (engrave), so i would like to change the color one i have in to a black and white one, but without any gray.
(so i can print it out, transfer it onto the glass and engrave it)
If i use a simple program like word, i can make it black and white, but it will have to much white and not enough black.

Hope you understand me.
Can anyone help me with that and tell me how to do that?
Thank you very much

RE: changing picture black and white
Your could try the threshold tool. Colors -> Threshold. It will reduce the image to b & w. Not very pretty but depending on image might be ok.

looks like this

Adjust the slider as indicated.
