HEIC conversion

[orkc]

What are you trying to achieve?

Convert range of image types including HEIC to JPEG. After reading the historical trail I can find I am confused as to if Sharp can be used for converting HEIC to JPEG and if so then how to achieve that. I think that the current situation is that the answer is yes for input and experimental for output but not with the standard install. However, I do not understand the steps required to complete an installation that will support HEIC conversion. Can anyone confirm my understanding and if accurate provide the correct steps?

At npm install time, sharp will always look for and, if found, compile itself again a globally-installed copy of libvips.

This means you'll need to compile and install libvips with support for libheif before installing sharp.

Please see #1105 (comment)

I install sharp in my local lambda function folder.
(npm install --no-cache --arch=x64 --platform=linux --target=10.15.0 sharp)
However it is not work (Error: Input buffer contains unsupported image format) , When Lambda was excuted.

How to compile globally-installed copy of libvips??

@vdongbin I notice you opened #2006 so let's continue your question there.

just in case it is helpful to others... With the pointer given by Lovell (thanks) I got things working by installing in the following order:

libheif
libvips
sharp

looking for the solution

I've installed the libvips42, libvips-dev, libvips-tools, libheif and rebuilt sharp
