Converting HEIC to other formats #258

Open nipunbatra opened 3 years ago

nipunbatra commented 3 years ago

HI, The convert utility is working great!

However, it fails to convert HEIC files.

$ convert IPAD-Photo\ 2.HEIC i.jpeg
convert: no decode delegate for this image format `HEIC' @ error/constitute.c/ReadImage/573.
convert: no images defined `i.jpeg' @ error/convert.c/ConvertImageCommand/3303.

I saw HEIC in the repo in imagemagick manual page: https://github.com/holzschu/a-shell/search?q=heic

I also tried a couple of Python solutions.


$ heic-to-jpg -s IPAD-Photo.HEIC
which: command not found
Program 'convert' not found!

FFMPeg also currently does not support HEIC conversion.

Various articles suggest that Imagemagick works: https://blog.wplauncher.com/convert-heic-to-jpg-on-mac/ Another resource using a different solution: https://github.com/libvips/libvips

While not really a deal breaker or urgent issue, I just wanted to put this up here.

Aside - I get a similar warning for JPEG -> PDF too, but that works out okay. The generated pdf is perfect.


$ convert Image-2.png Im.pdf
convert: delegate library support not built-in `Im.pdf' (ZLIB) @ error/pdf.c/WritePDFImage/1556.

It looks like https://github.com/strukturag/libheif can compile to webassembly, but it's emscripten webassembly, so may not be supported by a-Shell.

A temporary workaround (without using internet) is to use Shortcuts.

Upload

Shortcut link: https://www.icloud.com/shortcuts/e4f10d6e0ad44c128f34d2901fc3bb7f

However, this is a lot of clicks.

It would be great to have more functionality in convert command utility.

Alternatively, it would be interesting if the shortcuts could be called from command line and passed command line arguments (and if they can work without annoying pop ups/clicks needed)

Another relatively simple solution (in the interim): Open HEIC photo in Photos -> Share -> copy photo -> Goto Files -> Right click or Command V to paste. It is stored as a JPEG.
