Overlap One Image over Another

[mozgbrasil]

Good afternoon my friends

I have the following imagemagick command to overlay images

 composite -gravity Center image_resize.png canvas.png image.png

When I try the following way using its container, it returns an empty image

docker run -v ~/Imagens:/imgs dpokidov/imagemagick \
-composite -gravity Center /imgs/image_resize.png /imgs/canvas.png /imgs/$(date +%Y-%m-%d_%H-%M-%S)_image.png

Thank you in advance if you can help

Hey,

Thanks for creating this. Could you please share the image, so I can reproduce and show the version of the local IM (composite --version)?

I think -composite flag is different from composite entrypoint. The below worked for me:

docker run -v $(pwd):/imgs --entrypoint=composite dpokidov/imagemagick -gravity Center /imgs/image_resize.png /imgs/canvas.png /imgs/out.png

I just installed imagemagick and run the following command

composite -gravity Center image_resize.png canvas.png image.png

Which returned the expected result

Using the container the image is returned with error in the case in black and white

Looks like an IM bug to me. Just to make sure could you please post composite -version output here?

Yup, so it seems like an IM bug. I tested it on version 7.0.7-2 and it's working as expected:

docker run -v $(pwd):/imgs --entrypoint=composite dpokidov/imagemagick:7.0.7-2 -gravity Center /imgs/image_resize.png /imgs/canvas.png /imgs/out.png

Thank you my friend

I've also opened an issue in IM - ImageMagick/ImageMagick#4271

And it turned out that the latest version of IM needs an extra -colorspace -sRGB to make it work.
