Thumbnail gif file with crop: :centre always creates 1 scene gif #344
Description
Describe the bug
Vips::Image.thumbnail("filename.gif[n=-1]", 200, height: 200, crop: :centre) with animated GIF file saves static file with 1 scene only.
Without crop: :centre it saves animated file correctly
I used file https://i.pinimg.com/originals/96/50/f0/9650f01cd3334952b075f8cf55bedd60.gif for testing
To Reproduce
Steps to reproduce the behavior:
Run ruby script
# frozen_string_literal: true require "bundler/inline" gemfile(true) do source "https://rubygems.org" git_source(:github) { |repo| "https://github.com/#{repo}.git" } gem "ruby-vips" gem 'down' end GLib::logger.level = Logger::DEBUG tempfile = Down.download("https://i.pinimg.com/originals/96/50/f0/9650f01cd3334952b075f8cf55bedd60.gif") resized_image = Vips::Image.thumbnail("#{tempfile.path}[n=-1]", 400, height: 400, crop: :centre) resized_image.write_to_file "/tmp/rabbit-with-crop.gif" `browse /tmp/rabbit-with-crop.gif`Expected behavior
File must be animated with all scenes cropped
Additional context
I have libvips 8.13rc1 compiled with cgif
