I have a jpeg file, I want to add text to the bottom from the command line (i.e., without opening the jpeg with an app and adding the text by hand). I have tried using ImageMagick's convert or montage, their caption and annotate commands, but they don't work. I can turn the text into a gif with text2gif, that into a jpeg with ImageMagick's convert, and join them side-by-side with ImageMagick's adjoin command, but I want it beneath.

For those interested in the motivation, I wrote a script that fetches the 'New Yorker's cartoon-of-the-day and its caption. It'd be funnier if I could join them.

"-annotate" to write text on top of an existing image.

"-append" to join your images vertically

I regularly use -annotate, I've a script on a server that uses incrontab to automatically add text over the bottom left of any image that's uploaded in to a specific folder.

Thanks! I missed -append ; I didn't see that -annotate didn't work because the text was so small and I was looking at the bottom. I need to magnify the caption's text

From memory with annotate it can take a % value so that the text scales with the image. Theres also a "gravity" option so that southwest is the bottom left hand corner for positioning.

I haven't figured out how to make that work. I read /usr/doc/ImageMagick on command-line-processing (what I should have done in the first place): it doesn't mention this in the annotate section.

Thanks. I hadn't noticed 'gravity'. It's a big help.

magnifies $Caption by 2, appends it to the middle of the bottom of the screen, offset by nothing.

I joined the GraphicsMagick forum; one of the maintainers informed me

(which explained why my attempts to use 'scale' after 'text' failed) and , which addressed a problem I didn't have but is useful to know if I have a problem it would address in the future.

And a lot more than I asked for https://sourceforge.net/p/graphicsma...read/f307c74c/
