How to blend + translate simultaneously with Imagemagick?

[jhegedus42]

Hi ImageMagick Community!

Any idea how I can shift two images and blend them at the same time ?

I've illustrated this question here with images.

Cheers,

Jozsef

The apples also need enlarging. There are many ways to do this. One is (Windows BAT syntax):

Code: Select all

convert ^
  8BwgI.jpg ^
  ( VR76n.jpg ^
    -resize 150%% ^
    -alpha Opaque ^
    -channel A -evaluate Multiply 0.5 +channel ^
    -set page +1200+30 ^
  ) ^
  -background White ^
  -layers merge ^

Many thanks Snibgo, I try it.

I have a related question, is there a way to do this blending trick in ImageMagick ?

Yes; check out this link and a bit further up the page: http://www.imagemagick.org/Usage/photos/#double

I tried this command :

Code: Select all

convert input02.jpg  (input01.jpg -resize 150%% -alpha Opaque -channel A -evaluate Multiply 0.5 +channel -set page +1200+30)  -background White -layers merge a.jpg

and it gave me an error like :

Code: Select all

./convert.sh: line 10: syntax error near unexpected token `('
./convert.sh: line 10: `convert input02.jpg  (input01.jpg -resize 150%% -alpha Opaque -channel A -evaluate Multiply 0.5 +channel -set page +1200+30)  -background White -layers merge a.jpg'

I wonder what is the corresponding syntax in Linux?

[snibgo]

I had a space on each side of my parenthesis ( and ) . Why did you remove the spaces?

In Windows BAT, each % is (often) doubled. Not in bash.

Hi Snibgo,

I tried also this:

Code: Select all

convert input02.jpg  ( input01.jpg -resize 150% -alpha Opaque -channel A -evaluate Multiply 0.5 +channel -set page +1200+30 )  -background White -layers merge a.jpg

Same error.

[jhegedus42]

Code: Select all

convert input02.jpg  \( input01.jpg -resize 150% -alpha Opaque -channel A -evaluate Multiply 0.5 +channel -set page +1200+30 \)  -background White -layers merge a.jpg

run without error....

Magically it gives the wished result. Cool ! Thanks!

As you have not told us how you are running the code we have to guess. Linux needs \( \) but windows only needs ( )

Always provide your version of IM and platform. It saves time and frustration due to syntax issues.

Many thanks for the tip, that page is also very useful.

Ok, I read it more carefully once more.
