Rails image_tag旋转图像 [英] Rails image_tag rotates image

问题描述

我将Amazon S3用于配置了载波和雾的图像存储.这些图像似乎可以正确存储，但是当我有一个人像"图像(宽度小于高度)时，它不能正确显示，而是在侧面旋转图像.

I am using Amazon's S3 for image storage with carrierwave and fog configured. The images seem to store correctly however when I have a 'portrait' image (smaller width than height) it is not displaying correctly, but rather rotating the image on its side.

任何朝着正确方向的指针将不胜感激！

Any pointers in the right direction would be much appreciated!

uploaders/image_uploader.rb

uploaders/image_uploader.rb

class ImageUploader < CarrierWave::Uploader::Base
  include CarrierWave::RMagick

  include Sprockets::Helpers::RailsHelper
  include Sprockets::Helpers::IsolatedHelper

  storage :fog

  include CarrierWave::MimeTypes
  process :set_content_type

  process :resize_to_limit => [420, 0]

  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  def extension_white_list
    %w(jpg jpeg png)
  end

end

show.html.haml

show.html.haml

= image_tag(@idea.image_attachments.first.image.url).to_s

image_attachment.rb

image_attachment.rb

class ImageAttachment < ActiveRecord::Base
  require 'carrierwave/orm/activerecord'
  attr_accessible :image, :description
  belongs_to :image_attachable, polymorphic: true
  mount_uploader :image, ImageUploader
end

推荐答案

在uploader.rb文件中，尝试

in the uploader.rb file, try

process :auto_orient 

def auto_orient
 manipulate! do |image|
   image.tap(&:auto_orient)
 end
end

它应该修复它.
