LoadError: cannot load such file -- rmagick with dicom gem

I am writing a job that converts dcm to jpg images using the dicom gem

here is the code

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

here is what i get on console

I followed this issue on the github page here It suggested that if i am able to convert the dcm image to jpg directly using the command convert -debug module IM-0001-0001.dcm IM.jpg then dicom should not show any error. I am able to convert it to jpg using the console but dicom is throwing an error 2016-02-19T09:24:03.960Z 14165 TID-1kcakw WARN: LoadError: cannot load such file -- rmagick

Solution

  • The issue was fixed by upgrading rmagick to 2.13.4 or later.
