Changelog

Sourced from usvg's changelog.

[0.31.0] - 2023-04-10

Added

• usvg::Tree::paint_servers
• usvg::Tree::clip_paths
• usvg::Tree::masks
• usvg::Tree::filters
• usvg::Node::subroots
• (usvg) --coordinates-precision and --transforms-precision writing options. Thanks to @​flxzt.

Fixed

• fill-opacity and stroke-opacity resolving.
• Double transform when resolving symbol.
• symbol clipping when its viewbox is the same as the document one.
• (usvg) Deeply nested gradients, patterns, clip paths, masks and filters were ignored during SVG writing.
• Missing text in nested clip paths and mask, text decoration patterns, filter inputs and feImage.

[0.30.0] - 2023-03-25

Added

• Readd usvg CLI tool. Can be installed via cargo as before.

Changed

• Extract most usvg internals into new usvg-tree and usvg-parser crates. usvg-tree contains just the SVG tree and all the types. usvg-parser parsers SVG into usvg-tree. And usvg is just an umbrella crate now.
• To use usvg::Tree::from* methods one should import the usvg::TreeParsing trait now.
• No need to import usvg-text-layout manually anymore. It is part of usvg now.
• rosvgtree no longer reexports svgtypes.
• rosvgtree::Node::attribute returns just a string now.
• rosvgtree::Node::find_attribute returns just a rosvgtree::Node now.
• Rename usvg::Stretch into usvg::FontStretch.
• Rename usvg::Style into usvg::FontStyle.
• usvg::FitTo moved to resvg::FitTo.
• usvg::IsDefault trait is private now.

Removed

• rosvgtree::FromValue. Due to Rust's orphan rules this trait is pretty useless.

Fixed

• Recursive markers detection.
• Skip malformed transform attributes without skipping the whole element.
• Clipping path rectangle calculation for nested svg elements. Thanks to @​LaurenzV.
• Panic when applying text-decoration on text with only one cluster. Thanks to @​LaurenzV.
• (Qt API) Image size wasn't initialized. Thanks to @​missdeer.
• resvg CLI allows files with XML DTD again.
• (svgtypes) Handle implicit MoveTo after ClosePath segments.
