v2.2.0

• Fixed hard cutoffs at glyph edges where ink touches the bounding box (common in dense scripts like CJK). The inner distance transform now correctly sees outside-ink pixels in the surrounding buffer region (#63).
• Fixed glyph placement within the SDF texture for fonts where actualBoundingBoxLeft is non-zero. Glyphs are now correctly centered without phantom padding, producing slightly smaller textures. Downstream consumers that position quads via glyphLeft (e.g. mapbox-gl-js) render identically (#65).

v2.1.0

• Apply gamma correction to anti-aliased pixels. This makes the SDF-rendered text very slightly thicker and matches how browsers render the same text/font with HTML closer (by @xavierjs #61)
• Improve performance by ~10%.
• Fix glyph x alignment to use actual bounding box metrics, matching height behavior. #34
• Reintroduce using OffscreenCanvas by default where available, making TinySDF work in worker contexts. #35
• Better code comments to clarify logic. #10

⚠️ This release very slightly alters how text is rendered, which might require updating test expectations for downstream users.

v2.0.7

Add a lang option (passed through to the Canvas context) to handle subtle variations between Simplified Chinese, Traditional Chinese, and Japanese CJK rendering. #58

v2.0.6

• Fix an edge case with negative-width diacritics #50
• Fix glyphAdvance TypeScript type

v2.0.5

• Fix glyph clipping at the bottom in some cases #43 (by @boris-ulyanov)
• Fix a bug with TinySDF throwing an error when drawing characters with diacritic marks. #40
• Fix new TinySDF() producing an error if no options provided.

v2.0.4

Include TypeScript typings for real this time.

v2.0.3

Add TypeScript typings (thanks @HarelM!). #39

v2.0.2

• Temporarily remove OffscreenCanvas usage due to the current Chrome version (v93) having performance issues with it (not respecting willReadFrequently context option).

v2.0.1

• Fix TinySDF not instantiating in Web Worker context.
• Avoid publishing irrelevant files to NPM.

v2.0.0

⚠️ Breaking changes

• Change the API to accept an options object instead of arguments:

const tinySdf = new TinySDF({
  fontSize: 24,
  fontFamily: 'Arial'
});

• Simplify the API down to just a single draw method (that calculates glyph metrics by default).
• Change the shape of the return value for readability and consistency (see the docs).
• Drop support for Internet Explorer.
• Switch the package to ES Modules syntax.

✨ Other improvements

• Improve performance by up to 20%.
• Add fontStyle support.
• Fix major performance issues on certain Chrome/GPU combinations.
• Fix an issue where some glyphs where clipped by 1 pixel at the bottom. #33
