Thanks. I think there is a problem with -gravity center as well.
Example - this command:
Code: Select all
convert background.png foreground.png -background none -gravity center -composite merged.png
In 6.9.7-3 this centers the foreground image on the background image.
In 7.0.4-5 the foreground is placed in the top left corner.

Works fine for me in IM 7.0.4-5 Q16 Mac OSX
Code: Select all
magick logo: rose: -gravity center -composite tmp7.png
Perhaps one of your two input images have a virtual canvas with offset. Try adding +repage after reading the two images.

Images are simple PNG files. Adding +repage has no effect
The 'magick logo: rose: -gravity center -composite tmp7.png' works for me as well; but convert does not.

This is weird.
The following commands produce different results in 7.0.4-5 on OS X, even though the 'convert' app is just s symlink to 'magick'.
Code: Select all
convert background.png foreground.png -background none -gravity center -composite merged.png
Code: Select all
magick background.png foreground.png -background none -gravity center -composite merged.png
The 'magick' command properly centers the foreground image; but 'convert' places it in the top left corner.

There does seem to be a bug using "magick convert". Using just magick or just convert work fine. I submitted a bug report at
