I was trying to reproduce the hint in

imagemagick: append a label under image with font size

This is my source image:

enter image description here

convert red.png -pointsize 36 label:"Test label" -gravity center -append red2.png

But instead of the expected result (label placed on bottom centered) I got this

enter image description here

I don't think that imagemagick has a bug. So, what am I doing wrong?

Here the version's info

convert -version

Thanks to Mark I was able to spot the error.

It looks like I had GraphicsMagick and ImageMagick installed in parallel and somehow they both seam to interfere each other. I really have no clue.

So I uninstalled GraphicsMagick with all dependencies (which I never used) and reinstalled ImageMagick.

Now it works as it should.

In ImageMagick, label: creates a new image. So you need to append that below your red image. To do that you should use parenthesis processing to create the label: image. It is cleaner to read that way.

convert red.png \( -background white -fill black -pointsize 36 label:"Test label" \) -gravity center -append red2.png
