Because, who does not want that!

Building on what already exists in the article:

• using the anotate +X+Y you can make relative changes to the final position of the text within the resulting image
• using colorspace Gray makes the image grayscale (without affecting its quality)
• If you get an error regarding the font: convert -list font is your goto. (Any argument with a set list of possible values can be checked that way)

Feel free to use the following syntax after properly changing $in,$out,$quote:

convert $img -colorspace Gray -font RobotoMono-Nerd-Font-Bd -pointsize 75 -gravity West -interline-spacing 35 -fill white -annotate +100+50 $quote $out && open $out

Another update here:

Creating blank wallpaper backgrounds

If you want to keep it minimal, or simply reduce the visual load on your wallpapers you can do so by using a simple unique colors:

convert -size 3840x2160 canvas:"#11805b" blank_green.png

You can spice that up a little bit using gradient instead of canvas in the previous command. If you do so, you will need to specify the participating colors, separated by -. (I particularly liked #2236a8 and `` here)

Mass producing

#!/bin/zsh
#
create_wallpaper(){
    # 4 arguments
    # quote, author, source_file, output
    # Quote 
    quote=$1
    author=$2
    inputfile=$3
    outputfile=$4
    convert "$inputfile" \
    -font "Roboto-Bold" \
    -pointsize 100 \
    -fill white \
    -gravity SouthEast \
    -annotate +100+300 "$quote" \
    -font "RobotoMono-Nerd-Font-Bd" \
    -pointsize 50 \
    -fill "#CCCCCC" \
    -annotate +100+200 "$author" \
    "$outputfile"
}


if [[ $# -lt 3 && !(-f $1) && !(-f $2 || -d $2) ]]; then
    echo "Improper usage:"
    echo "\t$0 <quote_file> <image_file or dir> <output>"
    return 1
fi

if [[ ! -d $3 ]]; then
    echo "The output needs to be a directory"
    return -1
fi

# Quotefile "syntax":
# "quote"author
cat $1 | sort -u | while read quoteline
do
    quote="$(echo $quoteline | awk -F'"' '{print $2}')"
    author="$(echo $quoteline | awk -F'"' '{print $3}')"
    filehash="$(echo "$quoteline" | cksum - | awk '{print $1}')"
    author_pref="$(echo $author | awk '{print toupper($(NF))}')"
    outputfile="$3/${author_pref}_${filehash}_${$(basename $2)%.*}.png"

    if [[ -n $quote ]]; then 
        echo "Now creating wallpaper(s) for $quote by $author"

        if [[ -d $2 ]]; then
            find $2 -type f | while read -r inputfile; do
                outputfile="$3/${author_pref}_${filehash}_${$(basename $inputfile)%.*}.png"
                create_wallpaper $quote $author $inputfile $outputfile \;
            done
        else
            create_wallpaper $quote $author $2 $outputfile 
        fi
    fi
done

That script is not exactly fool-proof, but was helpful to me today.
