Hi All,
Actually I was having the following steps in GIMP and I was trying to see if theres equivalent command lines for those operations on imagemagick!! Please advice

- 3 layers from the same picture -

Change on the upper layer:

Mode: Overlay
Opacity: 22.2
Filter:
Edge Detect
*Laplace
*Neon
Blur
*Gaussian Blur (Blur Radius:5)

- Change on the Middle Layer:
Mode: Normal
Opacity 22.2
Filter:
Enhance
Sharpen (Value:99)
Blur
Gaussian Blur (Blur Radius:5)

-Changes on the Lower Layer
Mode: Normal
Opacity: 82.5
Filter:
Enhance
Wavelet Sharpen (Amount: 3.9) (Radius: 1.74)
Blur
Selective Gaussian Blur (Radius: 3.0) (Max. Delta:50)
Enhance
Sharpen (Value 99)
Blur
Selective Gaussian Blur (Radius: 5.0) (Max. Delta:134)
Selective Gaussian Blur (Radius: 5.0) (Max. Delta:134)
Artistic
Cartoon (Mask Radius:3.10 ) (Percent Black: 0.043)


Thanks,

IM can do most of what you ask, but not all. Some functions may have slightly different arguments. The ones I see in your list that IM does not include (though they may be possible to script) include: Neon, wavelet sharpen and cartoon.

I have some scripts that may help, for sharpening and cartoon effect. see cartoon, binomialedge, gaussianedge, sharpedge. also see my laplacian script (though you can provide your weights to IM function -convolve or -mophology convolve to get the same results.

IM does not have a wavelet sharpen, but one of my scripts or using -morphology convolve may get something close enough.

I don't know what Neon does and would have to study that from GIMP.

IM can separate channels and you can apply processing to each channel as desired and then recombine channels.
