Question

Unsupported color conversion request
*** WebP::EncoderError Exception: Cannot read input picture file
got this error on certain jpg file. while converting into jpg again from google does the job but why is this?
'''webp_path = "#{filename.ext}.webp"
# Encode (convert) image to webp format with passed options
WebP.encode(path, webp_path, options)
# HACK: Changing of this two instance variables is the only way
# I found to make CarrierWave save new file that was created
# by encoding original image.
#filename = webp_path.split('/').pop
#file = CarrierWave::SanitizedFile.new(
tempfile: webp_path,
filename: webp_path,
content_type: 'image/webp'
)'''

Answer 1

This is what I use successfully, obviously need MiniMagick installed on the dev computer and server:
class ImagesUploader < CarrierWave::Uploader::Base
include CarrierWave::MiniMagick
def store_dir
"uploads/story/#{model.created_at.strftime('%Y').to_s.underscore}/#{model.created_at.strftime('%m').to_s.underscore}/#{model.created_at.strftime('%d').to_s.underscore}"
end
def default_url(*args)
"/fallback.webp"
end
process :resize_to_fill => [1200, 677]
process convert_to_webp: [{ quality: 80 }]
version :preview do
process convert_to_webp: [{ quality: 80, resize_w: 470, resize_h: 265 }]
end
def extension_allowlist
%w(jpg jpeg gif png webp)
end
private
def convert_to_webp(options = {})
# Build path for new file
webp_path = "#{path}.webp"
# Encode (convert) image to webp format with passed options
WebP.encode(path, webp_path, options)
# HACK: Changing of this two instance variables is the only way
# I found to make CarrierWave save new file that was created
# by encoding original image.
#filename = webp_path.split('/').pop.split('.').first + '.webp'
#file = CarrierWave::SanitizedFile.new(
tempfile: webp_path,
filename: webp_path,
content_type: 'image/webp'
)
end
end
