Taking Screenshots Regularly with Gyazo

• Take a screenshot every 1-2 minutes.
• It might be very useful.
• Benefits:
  • When writing code, you can refer back to a screenshot if you want to restore something you deleted a few minutes ago but can’t remember what it was.
    • Same goes for writing articles.
  • Even if your written text accidentally gets deleted, you can restore it by referring to the screenshot.
• Drawbacks:
  • It’s very insecure from a security standpoint.
    • It records all sensitive information that could be leaked.
      • Moreover, because Gyazo is convenient, it allows for searching through OCR.
    • Is there any way to make it secure?

Procedure:

• Execute the following regularly using launchd:
  • Take a screenshot using AppleScript.
  • Merge screenshots of two screens using imagemagick.
  • POST to Gyazo API using curl.
• It seems that Gyazo performs better OCR on smaller images even with the same resolution.
  • I wonder if they resize larger images before applying OCR.

Note: The script assumes a two-screen setup. .scpt

tell application "System Events"
    set activeApps to name of application processes whose frontmost is true
    set activeApp to item 1 of activeApps
end tell
set activeApp to do shell script "echo " & quoted form of activeApp & " | sed -e 's/ /_/g'"
set shotTime to do shell script "date +\"%Y-%m-%d_%H:%M \" | awk '{$1=$1;print}'"
do shell script "screencapture -x ~/Desktop/Auto_Screenshots/001.png ~/Desktop/Auto_Screenshots/002.png "
do shell script "/usr/local/bin/convert +append ~/Desktop/Auto_Screenshots/001.png ~/Desktop/Auto_Screenshots/002.png ~/Desktop/Auto_Screenshots/merged.png"
delay 1
do shell script "curl -X POST -i \"https://upload.gyazo.com/api/upload?access_token=&desc=" & shotTime & "_Screenshot&app=" & activeApp & "\" -F imagedata=@/Users/bluemountain/Desktop/Auto_Screenshots/merged.png"

• There are quite a few failures due to timeouts (408).
