I have searched for this, I got the some idea from Resize missing.png depending upon style in paperclip but not the exact solution of the following scenario.

I have a form where user choose image size from dropdown, which is to upload and Then user upload the particular image.(I have validations for the same. used Paperclip::Geometry.from_file(image.queued_for_write[:original].path) for the same) . I want to reduce the quality of original Image using convert option like (-strip -quality 90). Is there any way to create a style for original image which will be based on the selected value from the dropdown.

For eg. I have following Image sizes in dropdown ['1230 X 615'],['1230 X 390'],['1230 X 180'],['1230 X 240'],['1230 X 30'],['1020 X 180'],['1020 X 240'],['180 X 180'],['180 X 240'],['610 X 180'],['610 X 240'],['810 X 180']

Then how to create style if user select ['1020 X 240'] size from dropdown while uploading image?

Any suggestions?

Thanks in advance

As my thought you want to set image size whenever you are creating and updating object. You can try this one or this one .

Thanks for help. Following approach I used and it is working fine without proc,

The ' ' in {:large=>' '} are taking dropdown selected size by default.

has_attached_file :image, { :styles => {:large => ''},
                                          :convert_options => { :large => '-strip -quality 80'}}.merge(SECTION_PATH).merge(BUCKET_PATH)
