imageSDLview

simple minimalistic python app that opens a given file using gdk-pixbuf or ImageMagick and displays it via sdl2.
It can open all image-formats that your gdk-pixbuf loaders and/or your version of ImageMagick are able to deal with, e.g.:
RAW: needs gdk-pixbuf-loader-libopenraw or ImageMagick+libraw20
heic: needs gdk-pixbuf-loader-libheif
avif: needs ImageMagick + python3-Wand + https://openrepos.net/content/lpr/libheif
jxl: needs ImageMagick + python3-Wand + https://openrepos.net/content/lpr/libjxl-jpeg-xl
exr: needs ImageMagick + python3-Wand
...

usage: python3 /usr/lib/python3.8/site-packages/imageSDLview/imageSDLview.py file

please change /usr/lib/python3.8/site-packages/imageSDLview/imageSDLview.py to match your display resolution:
#Change this to screensize of your device (960x540 is suitable for a JollaPhone aka Jolla1)
displayheight = 960
displaywidth = 540
