Your e.jpg and e3.jpg are different. Look at the edges. You can get a bigger difference by tweaking the "-modulate" numbers. And what was the input file for my first command, the one that goes: %IM%convert effect.jpg ^ -channel R -level -73.91%%,81.91%% ^ -channel G -level -4%%,96%% ^ -channel B ...

Pasting your command into a command window works for me. What values do you have for WIDTH, HEIGHT, DIM and MAX? Please post e.jpg and e3.png. (Put them somewhere like dropbox.com and paste the URLs here.) e.jpg http://i.imgur.com/8HAtpW7.jpg e3.jpg http://i.imgur.com/tiHEiOC.png Windows command ...

The windows versions does look good! Thanks!

So if I want to have this filter to be applied to various images of different sizes, how to go about it ?

I just tried this code, and I'm getting the original image as the output (without any vignette or any modifications) convert e.jpg ( -clone 0 -modulate 100,0,100 ) ( -size %DIM%x%DIM% radial-gradient: -gravity Center -crop %MAX%x%MAX%+0+0 +repage -resize "%WIDTH%x%HEIGHT%^!" -negate -write mpr:VIG ...

I dont know what happened, but its working now. I can generate the vignette mask. Thanks!
Is there a way to use this vignette mask in the original image without having to save it to vig_mask.png ?

Pasting those commands into a command window works fine for me. D:\web\im> FOR /F "usebackq" %L IN (`identify -format "WIDTH=%w\nHEIGHT=%h" e.jpg`) DO set %L D:\web\im>set WIDTH=334 D:\web\im>set HEIGHT=334 D:\web\im> FOR /F %i IN ('identify -ping -format "%[fx:max(%WIDTH%,%HEIGHT%)]" xc:') DO set ...

As a matter of fact, I did try it, but its not working.. FOR /F "usebackq" %L IN (`identify -format "WIDTH=%w\nHEIGHT=%h" e.jpg`) DO set %L FOR /F %i IN ('identify -ping -format "%[fx:max(%WIDTH%,%HEIGHT%)]" xc:') DO set MAX=%i FOR /F %i IN ('identify -ping -format "%[fx:int(%MAX%*sqrt(2)+0.5)]" xc ...

Yes. I meant bat. How to implement it at command prompt ?

I'm getting the error as

%%L was unexpected at this time

What am I doing wrong ?

My bad. Didnt see it as a bash script

I'll create a mask for a vignette. This is white in the centre, black in the corners, with equal values in the centre of each edge (thus has elliptical contours). FOR /F "usebackq" %%L IN (`%IM%identify -format "WIDTH=%%w\nHEIGHT=%%h" e.jpg`) DO set %%L FOR /F %%i ^ IN ('%IM%identify ^ -ping ...

Also please identify your version of IM and platform. My IM version is 6.8.7-0 and I'm running it on Windows (will the same code produce a different effect in Linux or other OS ?) If the OP provides the link to the original page, we might get a hint. I see that fmw42 has already posted the link ...
