From a7171af0a34f612d05667f1a5c35a4ca834da082 Mon Sep 17 00:00:00 2001 From: Eugen Rochko Date: Wed, 21 Feb 2018 03:40:12 +0100 Subject: Fix avatar and header issues by using custom geometry detector (#6515) * Fix avatar and header issues by using custom geometry detector Revert a part of #6508. The file passed to dynamic styles method was not actually a file, but an instance of Paperclip::Attachment, which broke all styles by always returning {} from the method. One problem with GIF avatars was that Paperclip::GeometryDetector reported wrong dimensions for them, e.g. 120x120 GIF avatar would for some reason be detected as 120x53. By writing our own geometry parser, we can use FastImage, which also happens to be faster than ImageMagick, to detect image dimensions, which are also correct. Unfortunately, this PR does not implement skipping a `convert` entirely if the dimensions are already correct, as I found no easy way to write that behaviour into Paperclip without rewriting the Paperclip::Thumbnail class. * Only invoke convert if dimension or format needs to be changed --- app/models/concerns/account_avatar.rb | 12 +++--------- app/models/concerns/account_header.rb | 12 +++--------- app/models/media_attachment.rb | 27 +++++++++++++++++++-------- app/models/preview_card.rb | 13 +++++++------ app/models/site_upload.rb | 4 ++-- 5 files changed, 34 insertions(+), 34 deletions(-) (limited to 'app/models') diff --git a/app/models/concerns/account_avatar.rb b/app/models/concerns/account_avatar.rb index 53d0d876f..619644c9a 100644 --- a/app/models/concerns/account_avatar.rb +++ b/app/models/concerns/account_avatar.rb @@ -7,15 +7,9 @@ module AccountAvatar class_methods do def avatar_styles(file) - styles = {} - geometry = Paperclip::Geometry.from_file(file) - - styles[:original] = '120x120#' if geometry.width != geometry.height || geometry.width > 120 || geometry.height > 120 - styles[:static] = { format: 'png', convert_options: '-coalesce' } if file.content_type == 'image/gif' - + styles = { original: { geometry: '120x120#', file_geometry_parser: FastGeometryParser } } + styles[:static] = { format: 'png', convert_options: '-coalesce', file_geometry_parser: FastGeometryParser } if file.content_type == 'image/gif' styles - rescue Paperclip::Errors::NotIdentifiedByImageMagickError - {} end private :avatar_styles @@ -23,7 +17,7 @@ module AccountAvatar included do # Avatar upload - has_attached_file :avatar, styles: ->(f) { avatar_styles(f) }, convert_options: { all: '-strip' } + has_attached_file :avatar, styles: ->(f) { avatar_styles(f) }, convert_options: { all: '-strip' }, processors: [:lazy_thumbnail] validates_attachment_content_type :avatar, content_type: IMAGE_MIME_TYPES validates_attachment_size :avatar, less_than: 2.megabytes end diff --git a/app/models/concerns/account_header.rb b/app/models/concerns/account_header.rb index 991473d8c..5ed8a9c83 100644 --- a/app/models/concerns/account_header.rb +++ b/app/models/concerns/account_header.rb @@ -7,15 +7,9 @@ module AccountHeader class_methods do def header_styles(file) - styles = {} - geometry = Paperclip::Geometry.from_file(file) - - styles[:original] = '700x335#' unless geometry.width == 700 && geometry.height == 335 - styles[:static] = { format: 'png', convert_options: '-coalesce' } if file.content_type == 'image/gif' - + styles = { original: { geometry: '700x335#', file_geometry_parser: FastGeometryParser } } + styles[:static] = { format: 'png', convert_options: '-coalesce', file_geometry_parser: FastGeometryParser } if file.content_type == 'image/gif' styles - rescue Paperclip::Errors::NotIdentifiedByImageMagickError - {} end private :header_styles @@ -23,7 +17,7 @@ module AccountHeader included do # Header upload - has_attached_file :header, styles: ->(f) { header_styles(f) }, convert_options: { all: '-strip' } + has_attached_file :header, styles: ->(f) { header_styles(f) }, convert_options: { all: '-strip' }, processors: [:lazy_thumbnail] validates_attachment_content_type :header, content_type: IMAGE_MIME_TYPES validates_attachment_size :header, less_than: 2.megabytes end diff --git a/app/models/media_attachment.rb b/app/models/media_attachment.rb index b6e5916cb..38f88e9f7 100644 --- a/app/models/media_attachment.rb +++ b/app/models/media_attachment.rb @@ -32,7 +32,18 @@ class MediaAttachment < ApplicationRecord IMAGE_MIME_TYPES = ['image/jpeg', 'image/png', 'image/gif'].freeze VIDEO_MIME_TYPES = ['video/webm', 'video/mp4'].freeze - IMAGE_STYLES = { original: '1280x1280>', small: '400x400>' }.freeze + IMAGE_STYLES = { + original: { + geometry: '1280x1280>', + file_geometry_parser: FastGeometryParser, + }, + + small: { + geometry: '400x400>', + file_geometry_parser: FastGeometryParser, + }, + }.freeze + VIDEO_STYLES = { small: { convert_options: { @@ -167,16 +178,16 @@ class MediaAttachment < ApplicationRecord end def image_geometry(file) - geo = Paperclip::Geometry.from_file file + width, height = FastImage.size(file.path) + + return {} if width.nil?
