cannot save cropped image (non-jpg image file)

[fongaboo]

Getting this everytime I attempt a crop:

Android 7.1.2 LineageOS 14.1

does this happen with every jpg file that you try to crop?
have you tried to save the croped file to a different folder?

It also happens to me.
It doesn't happen to every JPEG files. When the issue happens, it is of no use to save to different folders.

While the visible gui part of llcrop can handle jpg/gif/png
the processing part (i.e. the lossless cropping library) can only handle jpg files (but not pngs or gifs.)

The errormessage "cannot transcode" is an indecator for non-jpg.

TODO:

add lossy cropping of non jpg-files with a warning that quality may be lost

Coming from "Aves" gallery sharing a png screenshot to llcrop failes with the same error message if i then wanna save or redrirect further - even though i can visually edit first inside the gui.

First sharing to "imagepipe" - then as jpg to llcrop - "fixed" this though.
