CrImage::WEBP

WEBP module implements a decoder and encoder for WEBP images. The WEBP specification is at: https://developers.google.com/speed/webp/docs/riff_container

Reading WebP Images

# Read from file
image = CrImage::WEBP.read("image.webp")

# Read from IO
File.open("image.webp", "rb") do |file|
  image = CrImage::WEBP.read(file)
end

# Read configuration only (dimensions, color model)
config = CrImage::WEBP.read_config("image.webp")

Writing WebP Images

# Write to file (lossless VP8L format)
CrImage::WEBP.write("output.webp", image)

# Write to IO
File.open("output.webp", "wb") do |file|
  CrImage::WEBP.write(file, image)
end

# Write with extended format (VP8X container)
options = CrImage::WEBP::Options.new(use_extended_format: true)
CrImage::WEBP.write("output.webp", image, options)
