convert jpg to RGB components

[clownpleco]

I have jpg files and want to create single red, green and blue gray shade images. Is this possible?

I am not sure what you mean. If you mean to separate the RGB channels from the image, then

Code: Select all

convert image.jpg -separate channel.png

The result will be channel-0.png for red, channel-1.png for green and channel-2.png for blue.

Or

Code: Select all

convert image.jpg -channel r -separate red.png
convert image.jpg -channel g -separate green.png
convert image.jpg -channel b -separate blue.png
