linux-bash: -background color black doesn't work

[homer]

Good morning everybody,

I tried to use

Code: Select all

mogrify -extent 546x364 -gravity center -background black *.jpg

...but the background of the image is getting white. I tried also with

Code: Select all

mogrify -extent 546x364 -gravity center -fill "#000000" *.jpg

and with

Code: Select all

mogrify -extent 546x364 -gravity center -background "#000000" *.jpg

but without success; everytime the background color is getting white. Does anybody know what I'm doing wrong?

Thank you!

Code: Select all

mogrify -gravity center -background black -extent 546x364 *.jpg
