LoadError：无法加载这样的文件 - 使用dicom gem加载rmagick

我正在编写一份使用dicom gem将dcm转换为jpg图像的作业

这是代码

require 'RMagick'
require 'dicom'
include Magick
include DICOM


class DicomtojpgJob < ActiveJob::Base
  queue_as :dicom

  def perform(*args)
    puts "were are here"
    dcm_filename = args[0]
    dcm = DObject.read(dcm_filename)
    puts dcm.summary
    dcm_image = dcm.image
    name = dcm_filename.split('.')
    dcm_image.normalize.write(name[0]+".jpg")

    # img = ImageList.new("IM-0004-0044.jpg")
    # img.display
    # args[0].update_attributes(:asset_path_url)
    puts args[0]

    exit
  end

end

这是我在控制台上获得的内容

我在github页面here上关注了这个问题 它建议如果我能够使用命令convert -debug module IM-0001-0001.dcm IM.jpg直接将dcm图像转换为jpg，那么dicom不应该显示任何错误。 我可以使用控制台将其转换为jpg，但是dicom正在抛出error 2016-02-19T09:24:03.960Z 14165 TID-1kcakw WARN: LoadError: cannot load such file -- rmagick

我该如何解决这个问题

我从您建议的存储库中下载了第一张图像，并运行了以下命令：

convert -debug module IM-0001-0001.dcm a.jpg

我认为问题在于您缺少JPEG2000模块。您可以使用

检查已安装的代理人 
identify -version

Version: ImageMagick 6.9.3-0 Q16 x86_64 2016-02-19 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2016 ImageMagick Studio LLC
License: http://www.imagemagick.org/script/license.php
Features: Cipher DPC Modules 
Delegates (built-in): bzlib fontconfig freetype jng jp2 jpeg lcms ltdl lzma openexr png tiff webp x xml lib

在这里你看到我有jp2。如果您缺少该模块，则在安装并运行./configure时，请尝试添加以下内容以查找所需的开关：

./configure --help | grep -Ei "JP|2000"

然后以通常的方式运行configure和make以及make install。

答案 1 :(得分：0)

它还没有与RMagick合作。 但是使用mini_magick正常工作

要求'mini_magick'

DICOM.image_processor =：mini_magick

答案 2 :(得分：0)

通过将rmagick升级到2.13.4或更高版本来解决此问题。
