Pictures lose exif data after being loaded into vips

[fabianblum]

Hello everyone,

we use vips for our image processing and since the last operating system update from Debian Buster 10 to Bookworm 13 we have the problem that vips loses the exif data (especially the orientation) as soon as the image is loaded. However, it works analogously with imagick without any problems.

We are using

jcupitt/vips: 2.4 libvips: 8.14.5 (I have also tried the latest version but no change)

Here is the snippet

$buffer = file_get_contents('image.jpg');
$vips = Vips\Image::newFromBuffer($buffer);
$vips->writeToFile(__DIR__ . '/output.jpg');

I suspect that some lib is missing or has changed in the version but I couldn't figure out which one is the problem.

I tried libexif and libexiv2, but no improvement.

Do you have any idea whats missing?

Many thanks in advance

Huh, strange, it should work. I tried:

$ docker run -it --rm debian:bookworm

...
root@0e9504526db2:/# apt install libvips-tools wget --no-install-recommends

vips-8.14.1

So it has all the exif data.

Maybe you have several libvips on your system, and one of them has been built without libexif?

While building vips

curl -sL https://github.com/libvips/libvips/releases/download/v8.14.5/vips-8.14.5.tar.xz -o vips.tar.xz \
  && tar xf vips.tar.xz \
  && cd vips-8.14.5 \
  && meson setup build --buildtype=release --libdir=lib -Dintrospection=false  \

i get this, i think that is the problem

The build cant find the exif-header, but i can see it

and libexif is on the same spot

[jcupitt]

That message is normal, it's just a workaround for an annoying inconsistency in libexif packaging.

Your php is probably finding a different libvips at runtime that has been built without libexif support. I'd remove all libvips installs except the one you really want to use.

Thank you very much for your help and input. I have now been able to solve the problem. Strangely enough, it was the libmagickcore which was installed in two versions. After I removed the older version, it worked without any problems
