Adding HEIC support

[daneren2005]

We have users that are wanting to be able to use .HEIC files. Most edge case image formats we are able to just tell users no, but since Apple has thrown their weight being heic files it is becoming more difficult. iOS 11 saves everything in this format I believe.

It looks like libvips just added support very recently: libvips/libvips#671. It is now in the latest version 8.8.0: https://github.com/libvips/libvips/blob/1a836052385c220ad32f9ce0c9a3363f1f919ad6/ChangeLog#L26. Are you able to add HEIC files to the list of supported source files?

I have successfully implemented HEIF config decoder (need one for a format detection and dimensions checking). As soon as libvips 8.8.0 is released imgproxy will get HEIC support.

Ack I didn't realize 8.8 wasn't already out. Well thank you I look forward to that being added!

HI,

v2.3 includes HEIC support. Note that imgproxy converts HEIC to JPEG by default since web browsers do not support it yet. You can save images to HEIC by explicitly specifying heic format.

Sweet that sounds like what I wanted anyways. Thank you for all you do with this project it is awesome!

Hello @DarthSim, I'm trying to use imgproxy to resize&save images in HEIC for my iOS app

I'm using the following URL (with format:heic), but the service is logging this error Resulting image format is not supported: heic

https://example.domain/insecure/resize:fill:100:100/format:heic/g:sm/plain/gs://infltr-dev.appspot.com/testresize/landscape.jpg

did you manage to save images in heic format?

Hey @bcojan!

We dropped HEIC support as a resulting format as x265 is licensed under GPL-3. However, there is a BSD-3 licensed Kvazaar encoder, and they are working on adding its support to libheif, so imgproxy may get back full HEIC support in the future.
