如何通过graphicsmagick命令编辑或添加exif元数据?我尝试了以下内容:
gm convert -set EXIF:XPKeywords "bird, sleep, moon" bird.jpg bird2.jpg
我的命令正在成功执行,图像正在创建,但exif元数据未更新。

我不相信你可以用GraphicsMagick做到这一点,我会建议exiv2
这样:
exiv2 -M"add Exif.Image.XPKeywords Ascii 'bird,sleep,moon'" image.jpg
然后您也可以使用jhead
查看它们:
jhead -v image.jpg
JFIF SOI marker: Units: 0 (aspect ratio) X-density=1 Y-density=1
Exif header 50 bytes long
Exif section in Intel order
(dir has 1 entries)
Windows-XP keywords = "bird,sleep,moon"
