更改图像文件名称rmagick

Question

Rmagick文档不是最清楚的，我试过所有，但它不喜欢它？也许我误解Magick :: Info如何工作？

http://www.imagemagick.org/RMagick/doc/info.html

def crop_photo(url, x, y, w, h) 
image = Magick::ImageList.new 
urlimage = open(url) 
format = url.split('/')[-1].strip.split('?')[0].strip 
image.from_blob(urlimage.read) 
crop = image.crop(x,y,w,h) 
image = crop.to_blob 
    image.filename = format #doesn't work 
    self.filename = format #doesn't work 
end 

的帮助感激

为了节省图像或ImageList中使用write方法：

image.write(new_filename)
