Hi. how can I convert a folder with images at once? what command should I type if i want to save converted files to subdir?
i use command
Code: Select all
convert *.jpg -canny 0x1+10%+30% i*.jpg
I want to keep original image names to converted files. i need a pair of converted and original files. how can i do it?
Also, how can I change color mode and make bg white and edges black?

Please don't multi-post. I have deleted your other post.
Always state what version IM you use, on what platform.
To process multiple files, creating one output per input, use "mogrify".

Try "-negate". If your outputs are black and white, I suggest you write to png, not jpg.

Please post an example image to some free hosting service and put the URL here. That way we can see exactly what you are trying to do.

OK. Then snibgo's suggestion of adding -negate to your mogrify command should do what you want.

yes! worked. thanks a lot all of you guys!
i have only one issue here. morgify doesn't work with negate. -negate works works well 'convert' and renames files=(

This works fine for me using IM 6.9.10.16 Mac OSX
What is your exact command line and what version of ImageMagick and platform? Your syntax is likely wrong.
