Refresh preview problem

[og900aero]

I use Debian 12 Stable with bspwm tiling windows manager, and lf file manager, and I configured preview. But I have a big problem. Sometimes there are cases where the EXIF orientation of the completed images does not get a good value. Image viewers can handle this just fine, but the preview image will show it rotated. For this, I created a command that rotates the image in the right direction and saves the file under its original name (convert file -auto-orient file) The problem is that no matter how hard you do it, the preview image doesn't show it. It doesn't show even if I quit the lf program and open it again. It only updates if I open another window (no matter what program) and then the lf window shrinks and thus suddenly updates the preview image and now shows it well. What could be the problem? How should one of the scripts be modified?

The following config files use:

cleaner:

#!/bin/sh
if [ -n "$FIFO_UEBERZUG" ]; then
  printf '{"action": "remove", "identifier": "preview"}\n' >"$FIFO_UEBERZUG"
fi

lfrun

#!/bin/sh
set -e

cleanup() {
    exec 3>&-
rm "$FIFO_UEBERZUG"
}

if [ -n "$SSH_CLIENT" ] || [ -n "$SSH_TTY" ]; then
lf "$@"
else
[ ! -d "$HOME/.cache/lf" ] && mkdir --parents "$HOME/.cache/lf"
export FIFO_UEBERZUG="$HOME/.cache/lf/ueberzug-$$"
mkfifo "$FIFO_UEBERZUG"
ueberzug layer -s <"$FIFO_UEBERZUG" -p json &
exec 3>"$FIFO_UEBERZUG"
trap cleanup EXIT
lf "$@" 3>&-
fi

previewer:

#!/bin/sh

draw() {
if [ -n "$FIFO_UEBERZUG" ]; then
  printf '{"action": "add", "identifier": "preview", "x": %d, "y": %d, "width": %d, "height": %d, "scaler": "contain", "scaling_position_x": 0.5, "scaling_position_y": 0.5, "path": "%s"}\n' \
    "$4" "$5" "$2" "$3" "$1" >"$FIFO_UEBERZUG"
fi
  exit 1
}

hash() {
  printf '%s/.cache/lf/%s' "$HOME" \
    "$(stat --printf '%n\0%i\0%F\0%s\0%W\0%Y' -- "$(readlink -f "$1")" | sha256sum | awk '{print $1}')"
}

cache() {
  if [ -f "$1" ]; then
    draw "$@"
  fi
}

batorcat() {
if command -v batcat > /dev/null 2>&1; then
batcat --color=always --style=snip --pager=never --decorations=always "$file"

can you post those images that have bad exif values?

can you post those images that have bad exif values?

I sent email with example picture (jk@vin.ovh)

[jstkdng]

Should be working properly with latest commit, please do test.

[og900aero]

I try and working properly with problem's picture, but now the first opening of all non-landscape images (were fine originally too) is very slow (2-3 seconds).

[jstkdng]

Are those images just regular ones? Like, without exif and such?

[og900aero]

No. Also taken with a mobile phone and contains EXIF data. Ex: Orientation : Horizontal (normal). So the EXIF data is good, but it opens very slowly the first time you open it. But after that it's good. Even if I restart the machine. Is it hidden somewhere that you have already dealt with it?

[jstkdng]

Is it hidden somewhere that you have already dealt with it?

yeah, processed images are cached to prevent reprocessing later on

Can you post the images you are testing? maybe the processing I'm doing for the other exif cases aren't the best. Please don't email as I don't think my server can handle attachments properly.

[og900aero]

Example:

Orientation: Unknown (0)

Orientation: Rotate 90 CW

Orientation: Horizontal (normal)

Of this, in the old ueberzugpp, only the Rotate 90 CW version appeared badly, and it displayed them all at lightning speed, instantly. In the new version, all three display well, but it loads very slowly at first. However, if there is no EXIF (Unknown (0), or if it has a good value (Horizontal (normal)), then you don't have to deal with it, just display it.

How can I remove fresh ueberzugpp? I cloned to directory, and make install in past. Now I want uninstall this, and install from Debian 12 repo, because that version havent slow load problem (vertically picture). I try sudo make uninstall command in cloned directoty, but I get error message: No rule to make target 'uninstall'.

[jstkdng]

I think make install places all files under /usr/local/ you can remove them from it.

Cool. It worked.
