i have a raspberry pi, and im trying to crop an image thus.

i want a box 465pixels wide, 111high, with a top left pixel location of 175x780.

convert imageleft.jpg -crop 780x175+111+465 +repage chlorine.jpg

Does that command look right?

the image size is 2592x1944

You have your coordinates wrong. Crop is WxH+X+Y. So if you want a width=465 and height=111 at 175,780 top left corner, then use

Code: Select all

convert imageleft.jpg -crop 465x111+175+780 +repage chlorine.jpg
