User interface
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. You can also bring up a context menu via right click.
Using quick copy / quick move panels
Bring up the panel with C or M shortcut. You will see 9 destination directories, click on the folder icon to change them.
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.
Running scripts
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.
HiDPI (Linux / MacOS only)
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 is not supported.
qimgv should also obey the global scale factor set in KDE's systemsettings.
High quality scaling
qimgv supports nicer scaling filters when compiled with opencv support (ON by default, but might vary depending on your linux distribution). Filter options are available in Settings > Scaling. Bicubic or bilinear+sharpen is recommended.
Additional image formats
qimgv can open some extra formats via third-party image plugins. All of them are included with windows package.
| Format | Plugin |
|---|---|
| JPEG-XL | github.com/novomesk/qt-jpegxl-image-plugin |
| AVIF | github.com/novomesk/qt-avif-image-plugin |
| APNG | github.com/Skycoder42/QtApng |
| HEIF / HEIC | github.com/jakar/qt-heif-image-plugin |
