KDE Wayland: Tirando capturas de tela de regiões mais rápido?

  • 772

Estou usando este script do HN * para selecionar regiões na tela e copiar seu texto, tirei a linha com mogrify. Ele usa o Spectacle, mas demora um pouco antes de abrir a IU. É possível e seria mais rápido se o Spectacle permanecesse aberto em segundo plano? O slurp CLI inicia instantaneamente para mim para selecionar regiões, procurei ferramentas de captura de tela de linha de comando para talvez usar com ele ou tem seu próprio suporte de região, mas não encontrei nenhuma. Nenhum dos dois maim scrote grimnão funcionam no Plasma Wayland. Instalei o ksnip flatpak, mas a opção para regiões retangulares não aparece para mim.

* O roteiro:

  #!/bin/bash 
  # Dependencies: tesseract-ocr imagemagick 
  # on gnome: gnome-screenshot 
  # on kde: spectacle
  # on x11: xsel
  # on wayland: wl-clipboard

  die(){
    notify-send "$1"
    exit 1
  }
  cleanup(){
    [[ -n $1 ]] && rm -r "$1"
  }

  SCR_IMG=$(mktemp -d) || die "failed to take screenshot"

  # shellcheck disable=SC2064
  trap "cleanup '$SCR_IMG'" EXIT

  #notify-send "Select the area of the text" 
  if  which "spectacle" &> /dev/null
  then
    spectacle -n -b -r -o "$SCR_IMG/scr.png" || die "failed to take screenshot"
  else
    gnome-screenshot -a -f "$SCR_IMG/scr.png" || die "failed to take screenshot"
  fi

  # increase image quality with option -q from default 75 to 100
  mogrify -modulate 100,0 -resize 400% "$SCR_IMG/scr.png"  || die "failed to convert image"
  #should increase detection rate

  tesseract "$SCR_IMG/scr.png" "$SCR_IMG/scr" &> /dev/null || die "failed to extract text"
  if [ "$XDG_SESSION_TYPE" == "wayland" ]
  then 
    wl-copy < "$SCR_IMG/scr.txt" || die "failed to copy text to clipboard"
  else
    # xsel -b -i  < "$SCR_IMG/scr.txt" || die "failed to copy text to clipboard"
    xclip -selection clipboard -i < "$SCR_IMG/scr.txt" || die "failed to copy text to clipboard"  
  fi
  # Notify the user what was copied but truncate the text to 100 characters
  notify-send "Text extracted from image" "$(head -c 100 "$SCR_IMG/scr.txt")" || die "failed to send notification"
  exit  #!/bin/bash 
  # Dependencies: tesseract-ocr imagemagick 
  # on gnome: gnome-screenshot 
  # on kde: spectacle
  # on x11: xsel
  # on wayland: wl-clipboard

  die(){
    notify-send "$1"
    exit 1
  }
  cleanup(){
    [[ -n $1 ]] && rm -r "$1"
  }

  SCR_IMG=$(mktemp -d) || die "failed to take screenshot"

  # shellcheck disable=SC2064
  trap "cleanup '$SCR_IMG'" EXIT

  #notify-send "Select the area of the text" 
  if  which "spectacle" &> /dev/null
  then
    spectacle -n -b -r -o "$SCR_IMG/scr.png" || die "failed to take screenshot"
  else
    gnome-screenshot -a -f "$SCR_IMG/scr.png" || die "failed to take screenshot"
  fi

  # increase image quality with option -q from default 75 to 100
  mogrify -modulate 100,0 -resize 400% "$SCR_IMG/scr.png"  || die "failed to convert image"
  #should increase detection rate

  tesseract "$SCR_IMG/scr.png" "$SCR_IMG/scr" &> /dev/null || die "failed to extract text"
  if [ "$XDG_SESSION_TYPE" == "wayland" ]
  then 
    wl-copy < "$SCR_IMG/scr.txt" || die "failed to copy text to clipboard"
  else
    # xsel -b -i  < "$SCR_IMG/scr.txt" || die "failed to copy text to clipboard"
    xclip -selection clipboard -i < "$SCR_IMG/scr.txt" || die "failed to copy text to clipboard"  
  fi
  # Notify the user what was copied but truncate the text to 100 characters
  notify-send "Text extracted from image" "$(head -c 100 "$SCR_IMG/scr.txt")" || die "failed to send notification"
  exit

    Editei o script para tirar uma captura de tela de forma assíncrona, obter a região com slurpe usar magickpara cortá-la. Também multipliquei os valores de slurp 2x para considerar a escala de exibição de 200% que tenho.

      #!/bin/bash 

    die(){
    notify-send "$1"
    exit 1
  }
  cleanup(){
    [[ -n $1 ]] && rm -r "$1"
  }
  SCR_IMG=$(mktemp -d) || die "failed to take screenshot"
  trap "cleanup '$SCR_IMG'" EXIT

    spectacle -nbo "$SCR_IMG/scr.tiff" &
    region=($(slurp -b "#00000000" -c "#80808080" -w 2 -f "%w %h %x %y"))
    for i in "${!region[@]}" 
    do
        region[i]=$(expr ${region[i]} "*" "2")
    done
    magick "$SCR_IMG/scr.tiff" -crop "${region[0]}x${region[1]}+${region[2]}+${region[3]}" "$SCR_IMG/scr.tiff" 

    tesseract "$SCR_IMG/scr.tiff" "$SCR_IMG/scr" &> /dev/null || die "failed to extract text"
  wl-copy < "$SCR_IMG/scr.txt" || die "failed to copy text to clipboard"
  notify-send "Text extracted from image" "$(head -c 100 "$SCR_IMG/scr.txt")" || die "failed to send notification"
  exit
