Error `heifload: ignoring nclx profile` when converting to AVIF and resizing

[swissspidy]

For some images such as https://github.com/swissspidy/media-experiments/blob/f6a7f9f26694b79a25ae2b844d2cc9a344d356a7/tests/e2e/assets/wordpress-logo-512x512.png I am getting this error when trying to convert to AVIF:

Existing issues with same error:

• https://github.com/libvips/libvips/issues/1808
• https://github.com/libvips/libvips/issues/1888

Weird thing is that this is a PNG / AVIF situation, so not sure why HEIF would be involved here.

Here's a playground repro:

Hi @swissspidy,

It's safe to ignore this warning in this case. Upstream PR https://github.com/libvips/libvips/pull/3834 would remove this redundant warning.

Weird thing is that this is a PNG / AVIF situation, so not sure why HEIF would be involved here.

HEIF is a container, which supports HEVC and AV1 codecs used to create HEIC and AVIF images respectively. libvips leverages libheif to load/save these images.

Understood, thanks!

Is there a way to set the desired log level to hide info/warning/error messages?

[kleisauke]

The VIPS_WARNING environment variable is supposed to suppress these warning messages, for example:

const vips = await Vips({
  preRun: (module) => {
    // Hide warning messages
    module.ENV.VIPS_WARNING = 1;
  }
});

const im = vips.Image.newFromFile('x.avif');
im.writeToFile('x.png');

// Memory management
im.delete();

But, for some reason, it doesn't work for warnings emitted from side modules (i.e. vips-heif.wasm), which is curious.

I spent a couple of hours debugging to no avail, when I build wasm-vips without loadable modules, i.e.:

$ npm run build -- --disable-modules

The above program just works. :man_shrugging:

For now, I can recommend this workaround:

// Empty log handler
const log = (type, text) => void 0; // Or: console.log(`${type}: ${text}`);
const vips = await Vips({
  print: (text) => log('stdout', text),
  printErr: (text) => log('stderr', text),
});

v0.0.8 is now available and provides libvips v8.15.2.
