JUst turn off the green and blue channels!
Code: Select all
convert image.png -color-matrix '1,0,0 0,0,0 0,0,0' result.png
This has the same effect as using
+level-colors ,red a straight linear white to red modification of RGB values.
however is this what you want? You may get a better result by doing the level on a grayscale image!
Code: Select all
convert image.png -type grayscale +level-colors ,red result.png
Or doing both operations together using some varient of...
convert image.png -color-matrix '.2 .5 .3 0,0,0 0,0,0' result.png
