Unable to strip photos in HEIC format. #173

Closed huabin closed 3 months ago

Hello,

First thank you so much for creating this, I love it.

But there's an error, it seems unable to strip photos in HEIC format.

What did I do?

Run the command jpegoptim -s IMG_9230.HEIC

What did I get?

IMG_9230.HEIC  [ERROR]

What have I tried?

I tried several photos in HEIC format, all have this issue. And I tried to convert the photo's format to jpg. It works well.

Unfortunately heic image format is not jpeg and so you should not expect, that jpegoptim will work with it. You will get the same error with any non jpeg input.. like:

>jpegoptim -s jpegoptim.exe
jpegoptim.exe  [ERROR]

HEIC seems to be Apple's variant of HEIF. I don't see jpegoptim supporting HEIC, unless support for it is added to existing JPEG libraries (which seems unlikely).

@tjko I noticed that. Maybe, I should change the title to hope to add support for HEIC
