## Features

- Customizable appearance.
- Easy to use.
- In-app screenshot editing.
- DBus interface.
- Upload to Imgur.

## Usage

Executing the command `flameshot` without parameters will launch a running
instance of the program in the background without taking actions.
If your desktop environment provides tray area, a tray icon will also
appear in the tray for users to perform configuration and management.

Example commands:

- Capture with GUI:

```shell
flameshot gui
```

- Capture with GUI with custom save path:

```shell
flameshot gui -p ~/myStuff/captures
```

- Capture with GUI after 2 seconds delay (can be useful to take screenshots of mouse hover tooltips, etc.):

```shell
flameshot gui -d 2000
```

- Fullscreen capture with custom save path (no GUI) and delayed:

```shell
flameshot full -p ~/myStuff/captures -d 5000
```

- Fullscreen capture with custom save path copying to clipboard:

```shell
flameshot full -c -p ~/myStuff/captures
```

- Capture the screen containing the mouse and print the image (bytes) in PNG format:

```shell
flameshot screen -r
```

- Capture the screen number 1 and copy it to the clipboard:

```shell
flameshot screen -n 1 -c
```

In case of doubt choose the first or the second command as shortcut in your favorite desktop environment.

A systray icon will be in your system's panel while Flameshot is running.
Do a right click on the tray icon and you'll see some menu items to open the configuration window and the information window.
Check out the About window to see all available shortcuts in the graphical capture mode.

### CLI configuration

You can use the graphical menu to configure Flameshot, but alternatively you can use your terminal or scripts to do so.

- Open the configuration menu:

```shell
flameshot config
```

- Show the initial help message in the capture mode:

```shell
flameshot config --showhelp true
```

- For more information about the available options use the help flag:

```shell
flameshot config -h
```

### Config file

You can also edit some of the settings (like overriding the default colors) in the configuration file.\
Linux path: `~/.config/flameshot/flameshot.ini`.\
Windows path: `C:\Users\{YOURNAME}\AppData\Roaming\flameshot\flameshot.ini`.

When copying over the config file from Linux to Windows or vice versa,
make sure to correct the `savePath` variable,\
so that the screenshots save in the right directory on your desired file system.

## Keyboard shortcuts

### Local

These shortcuts are available in GUI mode:

Shift + drag a handler of the selection area: mirror redimension in the opposite handler.

### Global

Flameshot uses Print screen (Windows) and cmd-shift-x (macOS) as default global hotkeys.

On Linux, Flameshot doesn't yet support Prt Sc out of the box, but with a bit of configuration you can set this up:

#### On KDE Plasma desktop

To make configuration easier, there's a [file](docs/shortcuts-config/flameshot-shortcuts-kde.khotkeys) in the repository that more or less automates this process. This file will assign the following hotkeys by default:

If you don't like the defaults, they can be changed later.

Steps for using the configuration:

1. The configuration file makes Flameshot automatically save screenshots to `~/Pictures/Screenshots` without opening the save dialog. Make sure that folder exists by running:

```shell
mkdir -p ~/Pictures/Screenshots
```

(If you don't like the default location, you can skip this step and configure your preferred directory later.)
2. Download the configuration file:

```shell
cd ~/Desktop
wget https://raw.githubusercontent.com/flameshot-org/flameshot/master/docs/shortcuts-config/flameshot-shortcuts-kde.khotkeys
```
3. Make sure you have the `khotkeys` installed using your package manager to enable custom shortcuts in KDE Plasma.
4. Go to _System Settings_ → _Shortcuts_ → _Custom Shortcuts_.
5. If an entry exists for Spectacle (the default KDE screenshot utility), you'll need to disable it because its shortcuts might conflict with Flameshot's. Do this by unchecking the _Spectacle_ entry.
6. Click _Edit_ → _Import..._, navigate to the configuration file and open it.
7. Now the Flameshot entry should appear in the list. Click _Apply_ to apply the changes.
8. If you want to change the default hotkeys, you can expand the entry, select the appropriate action and modify it as you wish; the process is pretty self-explanatory.
9. If you installed Flameshot as a Flatpak, you will need to create a symlink to the command:

```shell
ln -s /var/lib/flatpak/exports/bin/org.flameshot.Flameshot ~/.local/bin/flameshot
```

#### On Ubuntu (Tested on 18.04, 20.04, 22.04)

To use Flameshot instead of the default screenshot application in Ubuntu we need to remove the binding on Prt Sc key, and then create a new binding for `/usr/bin/flameshot gui` ([adapted](https://askubuntu.com/posts/1039949/revisions) from [Pavel's answer on AskUbuntu](https://askubuntu.com/revisions/1036473/1)).

1. Remove the binding on Prt Sc:

Ubuntu 18.04/20.04 using the following command:
```shell
gsettings set org.gnome.settings-daemon.plugins.media-keys screenshot '[]'
```

Ubuntu 22.04: Go to _Settings_ > _Keyboard_ > _View and Customise Shortcuts_ > _Screenshots_ > _Take a screenshot interactively_ and press `backspace`

2. Add custom binding on Prt Sc:

Ubuntu 18.04: Go to _Settings_ > _Device_ > _Keyboard_ and press the '+' button at the bottom.

Ubuntu 20.04: Go to _Settings_ > _Keyboard Shortcuts_ and press the '+' button at the bottom.

Ubuntu 22.04: Go to _Settings_ > _Keyboard_ > _View and Customise Shortcuts_ > _Custom shortcuts_ and press the '+' button at the bottom.

3. Name the command as you like it, e.g. `flameshot`. And in the command insert `/usr/bin/flameshot gui`.

4. Then click "_Set Shortcut.._" and press Prt Sc. This will show as "_print_".

Now every time you press Prt Sc, it will start the Flameshot GUI instead of the default application.

#### On XFCE 4

1. Go to `Keyboard` settings
2. Switch to the tab `Application Shortcuts`
3. Find the entry

```text
Command Shortcut
xfce4-screenshooter -fd 1 Print
````
4. Replace `xfce4-screenshooter -fd 1` with `flameshot gui`

Now every time you press Prt Sc it will start Flameshot GUI instead of the default application.

## Considerations

- Experimental Gnome Wayland and Plasma Wayland support.

- If you are using Gnome you need to install the [AppIndicator and KStatusNotifierItem Support](https://extensions.gnome.org/extension/615/appindicator-support/) extension in order to see the system tray icon.

- Press Enter or Ctrl + C when you are in a capture mode and you don't have an active selection and the whole desktop will be copied to your clipboard. Pressing Ctrl + S will save your capture to a file. Check the [Shortcuts](#keyboard-shortcuts) for more information.

- Flameshot works best with a desktop environment that includes D-Bus. See this [article](https://wiki.archlinux.org/index.php/Flameshot#Troubleshooting) for tips on using Flameshot in a minimal window manager (dwm, i3, xmonad, etc).

- In order to speed up the first launch of Flameshot (D-Bus init of the app can be slow), consider starting the application automatically on boot.
- Quick tip: If you don't have Flameshot to autostart at boot and you want to set keyboard shortcut, use the following as the command for the keybinding:
```sh
( flameshot &; ) && ( sleep 0.5s && flameshot gui )
```

## Installation

Flameshot can be installed on Linux, Microsoft Windows, and macOS.

### Prebuilt packages

Some prebuilt packages are provided on [the release page of the GitHub project repository](https://github.com/flameshot-org/flameshot/releases).

### Packages from Repository

There are packages available in the repository of some Linux distributions:

- [Arch](https://archlinux.org/packages/extra/x86_64/flameshot/): `pacman -S flameshot`
+ Snapshot also available via AUR: [flameshot-git](https://aur.archlinux.org/packages/flameshot-git).
- [Debian 10+](https://tracker.debian.org/pkg/flameshot): `apt install flameshot`
+ Package for Debian 9 ("Stretch") also [available via stretch-backports](https://backports.debian.org/).
- [Ubuntu 18.04+](https://launchpad.net/ubuntu/+source/flameshot): `apt install flameshot`
- [openSUSE](https://software.opensuse.org/package/flameshot): `zypper install flameshot`

- [ALT](https://packages.altlinux.org/en/sisyphus/srpms/flameshot/): `su - -c "apt-get install flameshot"`
- [Snap/Flatpak/AppImage](https://github.com/flameshotapp/packages)
- [Docker](https://github.com/ManuelLR/docker-flameshot)
- [Windows](https://github.com/majkinetor/au-packages/tree/master/flameshot)

### MacOS

- [MacPorts](https://www.macports.org): `sudo port selfupdate && sudo port install flameshot`
- [Homebrew](https://brew.sh): `brew install --cask flameshot`

**Note** that because of macOS security features, you may not be able to open flameshot when installed using brew.
If you see the message `“flameshot” cannot be opened because the developer cannot be verified.` you will need to
follow the steps below:
1. Go to the Applications folder (Finder > Go > Applications, or Shift+Command+A)
1. Right-Click on "flameshot.app" and choose "Open" from the context menu
2. In the dialog click "Open"

After following all those steps above, `flameshot` will open without problems in your Mac.

### Windows

- [Chocolatey](https://chocolatey.org/packages/flameshot)

Expand this section to see what distros are using an up to date version of flameshot

### Tray icon

**Note** that for the Flameshot icon to appear in your tray area, you should have a systray software installed. This is especially true for users who use minimal [window managers](https://wiki.archlinux.org/index.php/window_manager) such as [dwm](https://dwm.suckless.org/). In some [Desktop Environment](https://wiki.archlinux.org/index.php/Desktop_environment) installations (e.g Gnome), the systray might be missing and you can install an application or plugin (e.g [Gnome shell extension](https://extensions.gnome.org/extension/1503/tray-icons/)) to add the systray to your setup. It has been [reported](https://github.com/flameshot-org/flameshot/issues/1009#issuecomment-700781081)) that icon of some software, including Flameshot, does not show in [gnome-shell-extension-appindicator](https://github.com/ubuntu/gnome-shell-extension-appindicator).

Alternatively, in case you don't want to have a systray, you can always call Flameshot from the terminal. See [Usage section](#usage).

## Compilation

To build the application in your system, you'll need to install the dependencies needed for it and package names might be different for each distribution, see [Dependencies](#dependencies) below for more information. You can also install most of the Qt dependencies via [their installer](https://www.qt.io/download-qt-installer). If you were developing Qt apps before, you probably already have them.

This project uses [CMake](https://cmake.org/) build system, so you need to install it in order to build the project (on most Linux distributions it is available in the standard repositories as a package called `cmake`). If your distribution provides too old version of CMake (e.g. Ubuntu 18.04) you can [download it on the official website](https://cmake.org/download/).

Also you can open and build/debug the project in a C++ IDE. For example, in Qt Creator you should be able to simply open `CMakeLists.txt` via `Open File or Project` in the menu after installing CMake into your system. [More information about CMake projects in Qt Creator](https://doc.qt.io/qtcreator/creator-project-cmake.html).
