Convert Watermark Bash Script to CLI Command

[fmw42]

Are you on Windows or a Unix type system. See my subsequent post above to the one you quoted. You are not using the commands that I recommended right above your last post here.

Also do not put spaces after the line ending \

Those commands work, only I'd prefer a command that automatically sizes the watermark text based on the dimensions of the image. In my bash script there's a setting *0.06000". I don't see that incorporated into these commands.

Code: Select all

export imageheight=$(echo "$(echo "$imagesize" | cut -f2 -d',')*0.06000" | bc)

I'm using Git Bash on Windows 10.

You can do that with IM 7.

So this code should do that then?

Code: Select all

magick "$file" -set option:dim "%wx%h" \
\( -background '#000000' -fill white -gravity center -size "%[dim]" caption:"$caption" \) \
-gravity south -composite "$file"

It just hangs when I run it.

I'm using ImageMagick 7.0.3-7 Q16 on 64-bit Windows 10 with Git Bash.

You keep going back to the wrong command line. See viewtopic.php?f=1&t=31002&p=140872#p140872

Also check your arguments to be sure they are what you think they should be.

Is it possible to add a border to the bottom of an image that is 10% the height of the image, and then overlay text on that border that automatically sizes to the height of the border?

As of now I've changed -background to none and have to manually create the border and then run this command:

Code: Select all

magick 0000.jpg -set option:dim "%w" \
\( -background none -font Times-New-Roman -fill white -gravity center -size "%[dim]x250" label:"Testing" \) \
-gravity south -composite 0_0.jpg

But for every image the dimensions change, so through trial and error I have to modify "%[dim]x250" to the correct size so that the text extends to the height (or doesn't surpass) of the border.

You set dim to just the width, but you could set it to both width and height (with "x") between them. The height could be an fx expression.

Code: Select all

-set option:dim "%wx%[fx:h*0.1]"

Then use:

Code: Select all

-size "%[dim]"

Did you want to overlay of top of the image, or append to the side of the image?
