# imagey
image viewer and maybe editor; inspired by mpv's simplicity
name is subject to change, suggestions welcome :)
## usage
```sh
# try it out!
nix run git+https://git.federated.nexus/electria/imagey
# install it imperatively
nix profile install git+https://git.federated.nexus/electria/imagey
```
keybinds are shown on startup if you didn't start it with an image
## known issues
### JXL
1. encoding is not implemented (jxl-oxide is decoding-only)
2. oreintation is incorrect in some cases
if the image has metadata oreintation AND
it's a jxl without the right extension OR
it's a jpeg with the jxl extension
this is due to the JXL decoder automatically rotating the image,
while the JPEG decoder (for instance) requires the extra step.
my workaround is to check the path of the input file,
not changing the oreintation if it has the jxl extension;
causing these caveats for cases where the extension is wrong.
### clipboard
1. large images (eg photos) don't seem to copy on linux/wayland,
(despite set_image not returning any error)
