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/lib/fast_geometry_parser.rb | 11 +++++++++++ 1 file changed, 11 insertions(+) create mode 100644 app/lib/fast_geometry_parser.rb (limited to 'app/lib/fast_geometry_parser.rb') diff --git a/app/lib/fast_geometry_parser.rb b/app/lib/fast_geometry_parser.rb new file mode 100644 index 000000000..5209c2bc5 --- /dev/null +++ b/app/lib/fast_geometry_parser.rb @@ -0,0 +1,11 @@ +# frozen_string_literal: true + +class FastGeometryParser + def self.from_file(file) + width, height = FastImage.size(file.path) + + raise Paperclip::Errors::NotIdentifiedByImageMagickError if width.nil? + + Paperclip::Geometry.new(width, height) + end +end -- cgit
