Hi,

First of all, thank you for this project. I spent dozens of hours trying to convert a HEIC file into JPG in my lambda function and I didn't find anything relevant.

I was able to use your Dockerfile to generate the nodejs10 compatible libs and I was also able to deploy my function with the new layer (deployed based on your project).
In the lambda function, requiring sharp works but when I try to convert the image, I get the same error message as if it was the version of sharp not compiled with HEIC:

Error: Input buffer contains unsupported image format

To validate that lambda is using the right custom version of sharp, I removed the layer attached to my function and sharp is not found anymore, so the version used is the good one from the layer.

Printing sharp.format:

sharp format: { jpeg: { id: 'jpeg', input: { file: true, buffer: true, stream: true }, output: { file: true, buffer: true, stream: true } }, png: { id: 'png', input: { file: true, buffer: true, stream: true }, output: { file: true, buffer: true, stream: true } }, webp: { id: 'webp', input: { file: true, buffer: true, stream: true }, output: { file: true, buffer: true, stream: true } }, tiff: { id: 'tiff', input: { file: true, buffer: true, stream: true }, output: { file: true, buffer: true, stream: true } }, magick: { id: 'magick', input: { file: false, buffer: false, stream: false }, output: { file: false, buffer: false, stream: false } }, openslide: { id: 'openslide', input: { file: false, buffer: false, stream: false }, output: { file: false, buffer: false, stream: false } }, dz: { id: 'dz', input: { file: false, buffer: false, stream: false }, output: { file: true, buffer: true, stream: true } }, ppm: { id: 'ppm', input: { file: false, buffer: false, stream: false }, output: { file: false, buffer: false, stream: false } }, fits: { id: 'fits', input: { file: false, buffer: false, stream: false }, output: { file: false, buffer: false, stream: false } }, gif: { id: 'gif', input: { file: true, buffer: true, stream: true }, output: { file: false, buffer: false, stream: false } }, svg: { id: 'svg', input: { file: true, buffer: true, stream: true }, output: { file: false, buffer: false, stream: false } }, heif: { id: 'heif', input: { file: false, buffer: false, stream: false }, output: { file: false, buffer: false, stream: false } }, pdf: { id: 'pdf', input: { file: false, buffer: false, stream: false }, output: { file: false, buffer: false, stream: false } }, vips: { id: 'vips', input: { file: true, buffer: false, stream: false }, output: { file: true, buffer: false, stream: false } }, raw: { id: 'raw', input: { file: false, buffer: true, stream: true }, output: { file: false, buffer: true, stream: true } } }

and sharp.versions:

sharp versions: { cairo: '1.16.0', exif: '0.6.22', expat: '2.2.9', ffi: '3.3', fontconfig: '2.13.92', freetype: '2.10.2', fribidi: '1.0.10', gdkpixbuf: '2.40.0', gettext: '0.21', gif: '5.1.4', glib: '2.65.2', gsf: '1.14.47', harfbuzz: '2.7.1', jpeg: '2.0.5', lcms: '2.11', orc: '0.4.31', pango: '1.46.1', pixman: '0.40.0', png: '1.6.37', svg: '2.49.4', spng: '0.6.0', tiff: '4.1.0', vips: '8.10.0', webp: '1.1.0', xml: '2.9.10', zlib: '1.2.11' }

It seems that HEIF / HEIC libs are not taken into consideration by sharp.

I wanted to validate that the files are available so I printed the content of /opt/lib directory:

I can see that Libvips and libheif.so.1 are present.
Do you have any idea why it's not including the right libs? Is there any path to specify?

Thank you
