如果不访问您的文件，很难提供帮助！以下是一些建议：
- 尝试在调试打开的情况下运行ImageMagick，查看是否可以发现差异：
magick-identific-debug-all-verbose 100U.tif - 尝试使用exiftool查看文件的组成：
exiftool-v-v 100U.tif
如果您有docker，您可以非常快速地运行一个一次性Alpine实例，并在其上安装ImageMagick，然后尝试如下操作：
docker run --rm -it -v "$(pwd)":/work alpine:latest
/ # apk add --no-cache imagemagick
/ # cd work
/work # magick 100U.TIF 100U.JPG

正如fmw42指出的，7.0.10-48似乎有一个bug（将尝试在问题跟踪程序中找到它）。更新到7.0.10-57修复了该问题。正如fmw42所指出的，7.0.10-48似乎有一个bug（将尝试在问题跟踪器中找到它）。更新到7.0.10-57修复了此问题。此问题与我的问题类似。我在更新imagemagick版本后解析
这个问题和我的问题一样。我在更新imagemagick版本后解析
不幸的是，我无法共享该文件。另一件事：我还将正确的jpg转换为tiff文件并返回，这导致了相同的问题，最后的结果中只有红色通道。7.0.10-48 Imagemagick可能有错误。你能试试别的版本吗。目前是7.0.11-6。这两个系统上都有什么版本的libtiff和libjpeg。如果不是最新的，你可以升级它们。哇。。非常感谢。使用7.0.10-57已经解决了这个问题。不幸的是，我无法共享该文件。另一件事：我还将正确的jpg转换为tiff文件并返回，这导致了相同的问题，最后的结果中只有红色通道。7.0.10-48 Imagemagick可能有错误。你能试试别的版本吗。目前是7.0.11-6。这两个系统上都有什么版本的libtiff和libjpeg。如果不是最新的，你可以升级它们。哇。。非常感谢。使用7.0.10-57已经解决了这个问题。我刚刚意识到，每个tiff到jpg的转换都失败了。因此，我拍摄了一张免费图像（），将其转换为tiff:
