convert HEIC/HEIF image file to jpeg by libheif & GD & php - end0tknr's kipple - web写経開発
先程の上記entry の関連です。
GD + libheif で、heic/heif->jpeg 変換できるのであれば、 imagemagick でも実施しようとしました。
が、imagemagick では動作せず、今回は諦めました。 (今後、imagemagickのverionがあがれば、できるのかもしれません)
install ImageMagick ImageMagick-devel
$ sudo su -
# yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

imagemagick では、heic/heif を認識せず...
imagemagick に付属する identify や convert コマンドで 試してみました。
## identifyで HEIFやHIECが表示されず... $ /usr/bin/identify -list format | grep -i HEIF ## convert でも、jpeg に変換できず... $ /usr/bin/convert IMG_0829.HEIC IMG_0829.JPG convert: no decode delegate for this image format `HEIC' @ error/constitute.c/ReadImage/566. convert: no images defined `IMG_0829.JPG' @ error/convert.c/ConvertImageCommand/3226.
