You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: code_fund_ads_image_analyzer.rb
    path of file: ./repos/code_fund_ads/app/analyzers
    
    the code of the file until where you have to start completion: class CodeFund
    
  def analyze
    return nil unless new_metadata[:height].present? && new_metadata[:width].present?
    size = "#{new_metadata[:width]}x#{new_metadata[:height]}"
    case size
    when "20x20", "40x40" then ENUMS::IMAGE_FORMATS::ICON
    when "200x200" then ENUMS::IMAGE_FORMATS::SMALL
    when "260x200" then ENUMS::IMAGE_FORMATS::LARGE
    when "512x320" then ENUMS::IMAGE_FORMATS::WIDE
    end
