Adding text before an image using imagemagick

Question

how can I add some text "before" an existing image using imagemagick? That means I have an image (a signature) and I would like to add some text (the current date) before the image, on the left side (not above or bottom). How can I do that? Ive tried it with append, but that havent worked for me :-(

Here is one exemple signature

And here it is how it should looks afterwards with the current date

Ive tried it with this code so far:

convert signature.png label:21.10.2019 -gravity West +append signature-with-date.png

Now Ive tried it with other order:

convert -gravity west label:21.10.2019 signature.png +append signature-with-date.png

But there is only white space before the image added, no text is shown

Ive tried it now with:

magick \( -size 400x -background white -gravity west label:21.10.2019 \) signature.png +append signature-with-date.png

Still not working

as you can see here

Please show the image you started with and how it is supposed to look afterwards - also, according to StackOverflow rules, you are supposed to show the code you have tried. — Mark Setchell

Change the order... convert -gravity west label:21.10.2019 signature.png +append signature-with-date.png — Mark Setchell

Or load in the same order but swap before appending... convert signature.png label:21.10.2019 -gravity West +swap +append signature-with-date.png — Mark Setchell

This works just fine for me on Imagemagick 6.9.10.68 Q16 Mac OSX.

Unix syntax:

convert \( -size 400x -background white -gravity west label:"21.10.2019" \) signature.png +append signature-with-date.png

Windows syntax:

convert ( -size 400x -background white -gravity west label:"21.10.2019" ) signature.png +append signature-with-date.png

What is your Imagemagick version and platform?

If on Imagemagick 7, use magick in place of convert.

Not sure why you have included the parentheses here? Normally I would only do that to make sure an operator doesn't get applied to some secondary image I don't want it to affect, but as you only have a single image loaded, I would have thought they were unnecessary?

I dont know why, but it doesnt work out for me :-( (tested with both magick and convert) I have posted the result in my question, please take a look there. my version is ImageMagick 7.0.8-68, OS: ‪CentOS Linux 7.7.1908 (Core)‬

Add a specific font to your command and see if that works. Perhaps your OS does not have a defined default font.

convert \( -size 400x -background white -gravity west -font arial label:"21.10.2019" \) signature.png +append signature-with-date.png

. If that does not work. Use the path to some font that you have on your system. What do you get from magick -version for you delegates? Does it include freetype and fontconfig? If not, add them and recompile.

Tried it with

magick \( -size 400x -background white -gravity west -font Helvetica label:"21.10.2019" \) signature.png +append signature-with-date.png

no other result than the one if posted above, no text.
