Your image is black and white. What color do you want. If black use -morphology edgein diamond:1. If white use -morphology edgeout diamond:1

[diegomage]

its not black and whit has various colors

[diegomage]

#340002
#340001
#340003
#340004

[diegomage]

[diegomage]

[diegomage]

#340002
#340001
#340003
#340004

Use your edge image (black and white) as a mask to color the lines by -compose multiply with your original image

try

Code: Select all

convert ZrFne.png \
\( -clone 0 -morphology edge diamond:1 -threshold 0 \) \
-compose multiply -composite result.png

how i could use the mask Im trying but i dont know how

I use this

Code: Select all

convert ZrFne.png   -mask  result.png       -fuzz 70% -transparent black   +mask zzlibre

What mask? Why are you using -mask? What is it you want to do? Please explain in more detail.

See the top-most post in this forum "IMPORTANT: Please Read This FIRST Before Posting" at viewtopic.php?f=1&t=9620 regarding asking intelligent questions.

this image have a four colors (ITS NOT BLACK AND WHITE )

[diegomage]

Please sorry for not explain well

[diegomage]

I see and another post that mask is not useful for extract edges

[fmw42]

I still do not know what you want for a result, nor why you are trying to use result.png from my command as the image with -mask. -mask is not the same as using a mask in composite. The image you just provided is now different from the original image you posted. I am very confused about what image you want to start and what you want to have as a result.

[fmw42]

Is this what you want?

Code: Select all

convert ZrFne.png -morphology edgeout diamond:1 result.png

or

Code: Select all

convert ZrFne.png -morphology edgeout diamond:1 -fill white -opaque black result2.png

or

Code: Select all

convert ZrFne.png \
\( -clone 0 -morphology edgeout diamond:1 -threshold 0 \) \
-compose multiply -composite -fill white -opaque black result3.png
