EITHER (a) your syntax might be faulty? Try:
$ convert test.heic test.jpg
OR (b) you need to install the two packages libheif-tool and libheif-devel into your Cygwin platform;
and then try the same thing:
$ convert test.heic test.jpg

Hello,

I have Cygwin with imagemagick 7.0.10-27 and I installed libheif just in case.

But when I try to convert from heic to jpg I get the following error:

$ magick test.heic test.jpg
magick: no decode delegate for this image format `HEIC' @ error/constitute.c/ReadImage/562.

$ mogrify -format jpg test.heic
mogrify: no decode delegate for this image format `HEIC' @ error/constitute.c/ReadImage/562.

Any ideas?

Thanks, ambrose

All working well. THANK YOU!

heic to jpg conversion

Does Cygwin include the capability to convert heic to jpg (or png or anything else Windows-readable)?
I tried "convert" (previously all-powerful) but that does not work (in any obvious way, anyway).
Thank you!

Works for me. What does `type convert` say?

Thomas,
are you sure ?

looking at the documentation
https://imagemagick.org/script/formats.php

we need libheif to support that format and
we have not yet it.

As expected
   identify -list format | grep -i heic

output is empty.

I will look on it.

Regards
Marco

Well, no, I just ran a simple test case which seems to have misled me. 
`convert x.jpg x.heic` did produce an image file with suffix .heic, 
without any complaint. However, `file x.heic` would identify it as JPEG 
format. Weird.

I have this:

~/tmp> type convert
convert is /usr/bin/convert
~/tmp> ls -x
L1a.heic  L2a.heic 
~/tmp> file *
L1a.heic: ISO Media
L2a.heic: ISO Media
~/tmp> convert L1a.heic L1a.jpg
convert: no decode delegate for this image format `HEIC' @ error/constitute.c/ReadImage/560.
convert: no images defined `L1a.jpg' @ error/convert.c/ConvertImageCommand/3258.

(BTW, in the above dialogue, should ISO Media read IOS Media?)

Apparently not although it came from MPEG developments of Apple Quicktime format
which gave rise to a slew of ISO standards:

	https://en.wikipedia.org/wiki/High_Efficiency_Image_File_Format

is part of ISO/IEC 23008-12 MPEG-H Standard, which also includes HEVC High
Efficiency Video Coding ITU-T H.265/.1/.2, some ITU-T H series supplements, and
MMT MPEG Media Transport;
it appears to be a specialization of ISO/IEC 14496-12:2004-2015 MPEG-4 Part 12
base media file format aka ISO/IEC 15444-12:2004-2015 JPEG 2000 Part 12 which
was dropped in 2017 in favour of the former, which is available in

http://standards.iso.org/ittf/PubliclyAvailableStandards/c068960_ISO_IEC_14496-12_2015.zip.


So HEIF would be a better file format label, whereas ISO media includes the
above (which not many people would think of), but could also imply ISO 9660:1988
for optical disks and archive images thereof (which most people would think of),
possibly including any or all of IEEE Rock Ridge (POSIX compatible extensions),
MS Joliet "Unicode" name extensions, El Torito bootable CD extensions, and/or
Apple ISO 9660 MacOS file extensions;
that also applies to the later replacement OSTA Optical Storage Technology
Association ISO/IEC 13346:1995-1999/ECMA-167:1997 UDF Universal Disk Format.

it seems the functionality to fully read heic format
was added in 7.0.9

http://www.imagemagick.org/script/changelog.php
I will look to build it.

I already built the libheif library, but does not work
with 6.9.x

The just uploaded ImageMagick 7 is able to convert
from heic to both jpg and png (and more I assume..)

I also added libheif and libde265 needed for the job
