tiny-skia

Fixed

• Path::compute_tight_bounds calculation. Thanks to @qbcbyb

Added

• Path::compute_tight_bounds

Changed

• MSRV bumped to stable, because of the flate2 crate.

Fixed

• Transform::is_valid was treating 1/4096 as zero. We need a higher precision.
• Build failure on AVX2 with --no-default-features. Thanks to @linkmauve

Changed

• MSRV bumped to 1.60, because of the log crate.

Fixed

• LineJoin::MiterClip handling with small miter_limit. Thanks to @torokati44

Added

• LineJoin::MiterClip. Thanks to @torokati44

Changed

• Rect::inset and Rect::outset are no longer require a mutable self. Thanks to @wezm

Added

• PathBuilder::push_path
• NonZeroRect
• Size
• Rect::transform
• Rect::bbox_transform
• Transform::from_bbox
• Transform::is_valid
• Transform::get_scale
• Transform::pre_rotate
• Transform::post_rotate
• Transform::pre_rotate_at
• Transform::post_rotate_at
• Transform::map_point

Changed

• ColorU8 and PremultipliedColorU8 are stored as [u8; 4] instead of u32. This fixes potential alignment issues and make the code easier to understand. Thanks to @e00E
• PathBuilder::push_rect accepts Rect and not f32 numbers now.

Removed

• tiny_skia_path::ScreenIntRect. It become private.
• Path::is_empty. Path cannot be empty by design.

Removed

• ColorU8::get and PremultipliedColorU8::get. Use the getters instead.

Added

• Reexport tiny_skia_path::PathStroker in tiny-skia.

Added

• Mask::from_vec
• Mask::from_pixmap to convert Pixmap into Mask by extracting alpha or luminance.
• Mask::width
• Mask::height
• Mask::data
• Mask::data_mut
• Mask::fill_path
• Mask::decode_png
• Mask::load_png
• Mask::encode_png
• Mask::save_png
• Mask::invert
• MaskType
• Pixmap::apply_mask

Changed

• Rename ClipMask into Mask.
• Mask is closer to a 8bit (A8) Pixmap now, rather than being its own thing.
• Mask::new requires width and height arguments now.
• Drawing on Mask using Mask::fill_path uses our SIMD pipeline now instead of a scalar code that should make it a bit faster.
• Painting API no longer returns Option<()>, but simply adds a warning to the log.
• Paint::anti_alias is set to true by default.

Removed

• Mask::set_path. Use Mask::fill_path instead.
• Mask::default(). Mask cannot be empty anymore.

Added

• Implement PartialEq for Paint and subtypes. Thanks to @hecrj

Changed

• MSRV bumped to 1.57, mainly because of the png crate.

Fixed

• ClipMasks larger than 8191x8191 pixels. Previously, the creation of a large mask via ClipMask::set_path would have created an empty mask.

Fixed

• Performance regression, probably due to LLVM update in Rust. Thanks to @mostafa-khaled775
• Big-endian targets support. Thanks to @ids1024

Added

• Pixmap::from_vec.

Fixed

• Increase Conic to Quad conversion precision. This allows us to produce nicer round caps. Previously, they were not as round as needed.

Fixed

• Conditional compilation of FasterMinMax on fallback platforms. Thanks to @CryZe

Added

• AArch64 Neon SIMD support. Up to 3x faster on Apple M1. Thanks to @CryZe

Changed

• FiniteF32, NormalizedF32 and NonZeroPositiveF32 types have been moved to the strict-num crate.
• Rename NormalizedF32::from_u8 into NormalizedF32::new_u8.
• Rename NormalizedF32::new_bounded into NormalizedF32::new_clamped.
• Use explicit SIMD intrinsic instead of relying on safe_arch.
• MSRV bumped to 1.51

Added

• tiny-skia-path dependency that can be used independently from tiny-skia. It contains the tiny-skia Bezier path implementation, including stroking and dashing. As well as all the geometry primitives (like Point and Rect).

Changed

• When disabling the std feature, one have to enable no-std-float feature instead of libm now.

Fixed

• Panic in Rect::round and Rect::round_out. Thanks to @Wardenfar

Fixed

• Minimum arrayref version.

Fixed

• Panic during non-aliased hairline stroking at the bottom edge of an image.

Fixed

• SourceOver blend mode must not be optimized to Source when ClipPath is present.

Fixed

• ClipMask::intersect_path alpha multiplying.

Added

• Support rendering on pixmaps larger than 8191x8191 pixels. From now, Pixmap is limited only by the amount of memory caller has.
• Transform::map_points
• PathBuilder::push_oval

Added

• WASM simd128 support. Thanks to @CryZe

Changed

• Transform::post_scale no longer requires &mut self.
• Update png crate.

Fixed

• Color memset optimizations should be ignored when clip mask is present.
• ClipMask::intersect_path logic.

Added

• ClipMask::intersect_path
• no_std support. Thanks to @CryZe

Changed

• Reduce Transform strictness. It's no longer guarantee to have only finite values, therefore we don't have to check each operation.

Removed

• Canvas. Call Pixmap/PixmapMut drawing methods directly.

Fixed

• Panic during path filling with anti-aliasing because of incorrect edges processing.

Fixed

• Endless loop during stroke dashing.

Changed

• Remove almost all unsafe. No performance changes.

Added

• PixmapRef and PixmapMut, that can be created from Pixmap or from raw data.
• Canvas::set_clip_mask, Canvas::get_clip_mask, Canvas::take_clip_mask.

Changed

• Canvas no longer owns a Pixmap.
• Canvas::draw_pixmap and Pattern::new accept PixmapRef instead of &Pixmap now.
• Improve clipping performance.
• The internal ClipMask type become public.

Fixed

• Panic when path is drawn slightly past the Pixmap bounds.

Removed

• Canvas::new

Changed

• Port to Rust.

Added

• Bindings to a stripped down Skia fork.
