Implement This Filter

[snibgo]

These are all Windows "bat" commands, not bash. Paste them into a file and execute it. For example, paste into a file called "hello.bat" than at the command line type "hello".

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

[snibgo]

Huh? You really want to type them at the command prompt? Just type them, but change every "%%" to "%". Good luck with that.

[johnthomas1433]

As a matter of fact, I did try it, but its not working..

Code: Select all

    
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:') DO set DIM=%i
convert -size %DIM%x%DIM% radial-gradient:  -gravity Center -crop %MAX%x%MAX%+0+0 +repage -resize "%WIDTH%x%HEIGHT%^!" vig_mask.png

Its giving me errors as shown below.


What am I doing wrong ?

[snibgo]

Pasting those commands into a command window works fine for me.

Code: Select all

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 MAX=%i

D:\web\im>set MAX=334

D:\web\im>    FOR /F %i IN ('identify -ping -format "%[fx:int(%MAX%*sqrt(2)+0.5)]" xc:') DO set DIM=%i

D:\web\im>set DIM=472

D:\web\im>    convert -size %DIM%x%DIM% radial-gradient:  -gravity Center -crop%MAX%x%MAX%+0+0 +repage -resize "%WIDTH%x%HEIGHT%^!" vig_mask.png

The values for WIDTH, HEIGHT, MAX and DIM will depend on your source file (effect.jpg). I used the left-hand square of the image you supplied.

You are, I hope, getting values for WIDTH etc? If not, did you run the first command I put on this thread?

Width and Height are getting set. But MAX and DIM are not getting set

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 ?

[snibgo]

Yes. The two convert commands can be combined:

Code: Select all

"%IM%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_MASK -level 50%%,95%% ^
  ) ^
  -composite ^
  ( -clone 0 -modulate 90,100,100 ) ^
  ( mpr:VIG_MASK -level 60%%,100%% ) ^
  -composite ^
  e3.png

[johnthomas1433]

I just tried this code, and I'm getting the original image as the output (without any vignette or any modifications)

Code: Select all

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_MASK -level 50%,95% ) -composite ( -clone 0 -modulate 90,100,100 ) ( mpr:VIG_MASK -level 60%,100% ) -composite e3.png

The entire command is written in a single line. I'm not getting any errors either. Just that no effect is being applied.

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.)

Here is my conversion of the PS tutorial into IM commands. Note this is limited to a square image of the size of the car image. For other square sizes, the circle arguments must be modified accordingly. For non-square image, replace the circle with an ellipse.



Unix

Code: Select all

convert car.jpg \
\( +clone -level 10x100% \) \
\( -clone 0 -fill black -colorize 100 -fill white -draw "circle 160,160 320,160" -blur 0x50 \) \
\( -clone 2 -negate -clone 1 -clone 0 -reverse  -compose over -composite \) -delete 0,1 \

Windows (please correct if in error)

I will build a script for this shortly.

That's a heroic effort, fmw. The Windows version looks and works fine.

Thanks. It did take a few hours to get it all working correctly. The tutorial was a little obscure for those not fully familiar with PS.

[johnthomas1433]

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 ?
