Hi, Currently I’m using the file\_column plugin to upload images and save multiple copies of each at 3 different resoltions: file\_column :name, :magick =\> { :versions =\> { “thumb96” =\> “96x150\>”, “medium250” =\> “250x400\>”, “large480” =\> “480X640\>” } } I am wondering if there’s any way I can declare other rmagick options at the same time, specifically the -quality attribute, since the jpegs it outputs by default of very poor quality (serious compression artifacts). I tried the following: file\_column :name, :magick =\> { :quality =\> ‘90’, :versions =\> { “thumb96” =\> “96x150\>”, “medium250” =\> “250x400\>”, “large480” =\> “480X640\>” } } but it doesn’t seem to have any effect. Is it possible to send other rmagick parameters to file\_column if you are already using the :versions option? If not, any ideas on how I could work around this? Thanks, Sean ---

Hi All, Regarding the problem I was having below, after going through some of the file\_column source, it seems that only specific rmagick options get processed, namely those that are hardcoded into the plugin by the developer: :crop, :size and :versions. I was a little surprised because the documentation seemed to imply that general rmagick options could be passed via the options hash. Of course I am a newbie to Ruby so I could just be reading the code wrong. So, I want to modify the file\_column source to ensure that when images are resized they are saved with a higher quality jpeg compression than is the default. In rmagick\_file\_column.rb, in the resize\_image method definition, I change the following: ``` if img_options[:size] img = img.change_geometry(img_options[:size]) do |c, r, i| i.resize(c, r) end ``` to: ``` if img_options[:size] img = img.change_geometry(img_options[:size]) do |c, r, i| self.radial_blur = 15 i.resize(c, r) end ``` I’ve just used radial\_blur as a stand in rmagick method for now because the results will be more readily apparent through visual inspection than changing jpeg compression quality. The change I made doesn’t seem to have any effect. Any ideas? Thanks, Sean ---

Hi All, Sorry for the noise on this lonely thread. I actually found an answer to my problem. The quality setting has to be passed to the .write method, which is called just after the resize method definition. I changed it to this: ``` ensure img.write(dest_path) { self.quality = 100 } File.chmod options[:permissions], dest_path end ``` The images look much better now.

Not sure if the post is anywhere active, but the tag does have support for quality (and probably most other things) through the ‘attributes’ parameters. so you want to do something like file\_column :name, :magick =\> { :versions =\> { “thumb96” =\> “96x150\>” }, :attributes =\> { :size =\> 100 } } Alien8 Recordings wrote: > Hi All, > > Sorry for the noise on this lonely thread.
