Hi all,



Is there a possibility to use the tool 'compare' contained in the 'ImageMagick' through Switch tool 'Execute command'? I did some tests with the command line and it works well.

I don't know how to indicate two input files to be able perform the operation.

I would like to make it like this:

'Input folder (with files to compare)' -> compare -> output folder (with file comparison)





Thanks in advance,

Aleksander

I don't know much about ImageMagick apart from using the PHP library. But if you figure out how to specify the input files in command line, you could probably define some temporary files (or static ones on your filesystem) using the File class. Once those temporary paths are tied to a variable, I imagine you could pass that into ImageMagick. Hope that helps

Hi Gabriel,

What you say makes sense, but I have no idea how to do it

Could you show an example?

I wrote this configurator for Imagemagick's compare

I'm pleasantly surprised, it works great.

Good job Dwight, thank you very much!

Maybe just one little question

Where should I add options to compare command?

Edit the script, find the lines that start with argv[argc++] and add or modify options.

Thanks again Dwight,

I have some trouble with that.

When I'm adding an option with the existing I have error "Failed to run external process"





args[argc++] = appPath+" -metric AE -fuzz 5%";

args[argc++] = job.getPath()+"/"+entries[0];

args[argc++] = job.getPath()+"/"+entries[1];

args[argc++] = differenceFN;





If I'm adding separate, option has no effect





args[argc++] = appPath;

args[argc++] = " -metric AE -fuzz 5%";

args[argc++] = job.getPath()+"/"+entries[0];

args[argc++] = job.getPath()+"/"+entries[1];

args[argc++] = differenceFN;





Do you have any idea?

Follow the pattern that is already there for arguments



args[argc++] = appPath;

args[argc++] = "-metric"; args[argc++] = "AE";

args[argc++] = "-fuzz"; args[argc++] = "5%";

args[argc++] = job.getPath()+"/"+entries[0];

args[argc++] = job.getPath()+"/"+entries[1];

args[argc++] = differenceFN;

So, it was reason

Of course works correctly.



Big thanks again!

Hello Dwight! I know this is a little old, but I would really appreciate some help on this if possible.

I'm trying to run your script but it's giving an error:
Thanks
