[feat] Is it possible to displace two pics in a row?

[xuwei152]

I am using this excellent tool. I am wondering if it is possible to display two pics in a row by a command like

tupimage img1.png img2.png

. It is helpful when we want to have a comparison between two pngs.

Thanks in advance.

Unfortunately, there's currently no direct way to achieve this. However, you can redirect the placeholders to files and then use paste. You can find an example in test_uploading_script.sh:

draw_strips() {
    local i=0
    local total_cols=0
    local max_cols="$(tput cols)"
    local opts="$1"
    shift
    for file in "$@"; do
        (( i++ )) || true
        tupimage "$file" $opts --save-info "$tmpdir/info" -o "$tmpdir/tmp"
        cols="$(grep columns "$tmpdir/info" | cut -f 2)"
        if (( $total_cols + $cols > $max_cols )); then
            paste -d "" "$tmpdir/out_"*
            rm "$tmpdir/out_"*
            total_cols=0
        fi
        (( total_cols += cols )) || true
        mv "$tmpdir/tmp" "$tmpdir/out_$(printf "%02d" $i)"
    done
    paste -d "" "$tmpdir/out_"*
    rm "$tmpdir/out_"*
}

# The height of each image will be 9 rows
draw_strips "-r 9" *.png

It's a bit ugly, but it actually wraps the images correctly if they exceed the screen width.

I'm currently in the process of rewriting tupimage in python, and I will definitely include this feature, but it's going to take time.

Thanks for the script. It works for me. Looking forward to the tupimage in Python.
