The idea is to have a uncluttered, simple and easy to use UI. You can see UI elements only when you need them.
There is a pull-down panel with thumbnails, as well as folder view (accessible by pressing Return).
You can also bring up a context menu by right-clicking an image.
Bring up the panel with C or M shortcut. You will see 9 destination directories, click them to set them up.
With panel visible, use 1 - 9 keys to copy/move current image to corresponding directory.
When you are done press C or M again to hide the panel.
You can run custom scripts on a current image.
Open Settings > Scripts. Press Add. Here you can choose between a shell command and a shell script.
Example of a command:
convert %file% %file%_.pdf
Example of a shell script file ($1 will be image path):
#!/bin/bash
gimp "$1"
Note: The script file must be an executable. Also, "shebang" (#!/bin/bash) needs to be present.
When you've created your script go to Settings > Controls > Add, then select it and assign a shortcut like for any regular action.
If qimgv appears too small / too big on your display, you can override the scale factor. Example:
QT_SCALE_FACTOR="1.5" qimgv /path/to/image.png
You can put it in qimgv.desktop file to make it permanent. Using values less than 1.0 may break some things.
qimgv should also obey the global scale factor set in KDE's systemsettings.
qimgv supports nicer scaling filters when compiled with opencv support (ON by default, might vary depending on your distribution). Filter options are available in Settings > Scaling. Bicubic or bilinear+sharpen is recommended.
APNG is supported via third-party qt plugin. (Included in windows qimgv package)
If you are linux user, install the latest QtApng by Skycoder42.
Apple's heif format is supported via third-party qt plugin. Included in windows qimgv package.
See github.com/jakar/qt-heif-image-plugin
qimgv can open jxl files via third-party qt plugin.
See github.com/novomesk/qt-jpegxl-image-plugin
qimgv can open avif files via third-party qt plugin.
See github.com/novomesk/qt-avif-image-plugin
Viewing raw is supported via qtraw plugin. (Included in windows qimgv package)
Arch Linux / Manjaro / etc.:
AUR package:
qimgv-git
Ubuntu / Linux Mint / Pop!_OS / etc.
sudo add-apt-repository ppa:easymodo/qimgv
sudo apt-get update
sudo apt install qimgv
Alternative package with kde support:
sudo apt install qimgv-kde
Gentoo:
emerge qimgv
OpenSUSE:
zypper install qimgv
Void linux:
xbps-install -S qimgv
Alpine Linux:
apk add qimgv
Fedora:
sudo dnf install qimgv
If your favorite distro is not included refer to [Manual install] section at the end of this document.
Windows builds are portable (everything is contained within install folder).
Installer additionally sets up file associations.
Note: in order to compile you will need gcc 8 or later!
Install dependencies ( gcc >= 9.0, git, cmake >= 3.13, qt >= 5.9, exiv2, mpv, opencv (core and imgproc )
Ubuntu & derivatives:
sudo apt install build-essential git cmake qt5-default libmpv-dev gcc-8 g++-8
Optional: libkf5windowsystem-dev
Fedora:
Enable RPMFusion https://rpmfusion.org/Configuration.
It is needed for video playback (mpv), but you also can build without it. See CMake build options at the end.
sudo dnf install git cmake make qt5 qt5-devel gcc-c++ mpv mpv-libs-devel exiv2-devel opencv opencv-devel
Optional: kf5-kwindowsystem
Configure & install
Get sources
git clone https://github.com/easymodo/qimgv.git
cd qimgv && mkdir -p build && cd build
Configure
cmake ../ -DCMAKE_INSTALL_PREFIX=/usr/ -DCMAKE_INSTALL_LIBDIR=lib
Build
make -j`nproc --ignore=1`
Install
sudo make install
- If you get errors like "/usr/lib64 exists in filesystem" during install:
add -DCMAKE_INSTALL_LIBDIR:PATH=/usr/lib to cmake command.
- If you get some errors like "std::filesystem not found":
qimgv needs a compiler with c++17 support - for example gcc 8.0+ (every recent distro has it)
If you have multiple version of gcc installed you might need to specify a which version for cmake to use, for example
CC=gcc-8 CXX=g++-8 cmake [........]
| Option | Default value | Description |
|---|---|---|
| VIDEO_SUPPORT | ON | Enables video playback via mpv |
| EXIV2 | ON | Support reading exif tags via exiv2 |
| OPENCV_SUPPORT | ON | Enables high quality scaling options |
| KDE_SUPPORT | OFF | Use some features from KDE, like background blur |
Usage example:
cmake ../ -DKDE_SUPPORT=ON -DCMAKE_INSTALL_PREFIX=/usr/
