我有以下代码,它调整大小和图像,然后添加一些十六进制背景。在localhost上这是有效的,但在heroku上我得到以下错误
version :big do
process :offer_resize_and_pad
end
def offer_resize_and_pad
img = resize_and_pad(600, nil, model.hex, 'Center')
img
end
"Photo Failed to manipulate with MiniMagick, maybe it is not an image? Original Error: Command (\"mogrify -thumbnail \"600x>\" -background \"#fff\" -gravity \"Center\" -extent \"600x\" /tmp/mini_magick20130217-2-1hts61y.jpg\") failed: {:status_code=>1, :output=>\"mogrify: Empty JPEG image (DNL not supported)

答案 0 :(得分:0)
我使用了RMagick而不是Mini_magick,有一些语法更改,它似乎工作:)。
include CarrierWave::RMagick
def offer_resize_and_pad
img = resize_and_pad(600, 280, model.hex, ::Magick::CenterGravity)
img
end
