How to take screenshots with shutter while editor is open?

Question

I am using shutter to create screenshots. The workflow that I would like to do is something like this:

1. Create a giant image 900x9000 px.
2. Open the image in the shutter editor
3. Take screenshots with the shutter screenshot tool and add them to my giant image. I am currently documenting a bug that takes 10 different steps to reproduce, so I want to create a single screenshot containing the 10 steps.

Unfortunatly, this isn't working, because I need to close the shutter editor before I can grab more screenshots.

If I try to open a second instance of shutter, I get this:

[May-11 10:49][~]$ shutter
WARNING: Gtk2::AppIndicator is missing --> there will be no icon showing up in the status bar when running Unity!

INFO: There is already another instance of Shutter running!

I would accept answers any answers that allow me to keep an editor open while making more screenshots. Options I have considered:

• Find a way to take screenshots from shutter while the editor is open
• Find a way to force shutter to open a second instance
• Find another image editor with similar functionality to shutter
• Find another screenshot grabber and use shutter strictly for editing

I am using Shutter 0.93.1 rev 1278 on CentOs and Ubuntu.

Answer 1

If you're using (and comfortable with) Shutter for editing, the simplest method might be to just use a different screenshot program to capture screenshots of your Shutter window. kazam, gnome-screenshot, screenie-qt, and screengrab are all in the Ubuntu software repositories and could accomplish this.

To install one of them using the command line, you can open a terminal (Alt+Control+T) and type

sudo apt update

sudo apt install screenie-qt

(replacing screenie-qt with the name of whatever one you want to install)

If you want a screenshot of terminal only then you can try this (I am not sure you are looking for this). You can run this command from a separate terminal and get the screenshot of your main terminal.

import -windows "<title_of_terminal>" filename.png

Generated image file will be saved under your home as : ~/home/filename.png
PS-You can rename the terminal before using this for easy use. Don't forget the quotes for terminal title.

Also, you can check pre-assigned shortcuts for screenshots here and try:

Settings > Keyboard > 'Shortcut' tab > 'Screenshot' menu item

Good luck.
