v0.8.2

Fixed winding issue when intra-glyph reused paths encoded as glyph components overlap with one another and have a negative-determinant affine transform that reverse the contour direction. When this happens, we do not reuse the paths as components, but encode them separately as simple contour glyphs (#287, #289).

v0.8.1

• Use xlink:href (SVG1.1) instead of unqualified href (SVG2) attributes in <use> elements, so that OT-SVG fonts built with --color_format=picosvg (where same shapes get reused between/within glyphs) are displayed correctly in Safari and Adobe apps (#271, #264, #266).
• Strip empty <defs/> element when no gradients defeind in --color_format=picovsvg (#272)
• Add workaround for Safari's bug when gradientTransform contains a matrix whose inverse is equal to itself (#268, #273).
• Fixed bug in --color_format=picosvg whereby we were applying intra-glyph shape reuse only for the first occurrence of a given painted layer in a color glyph, but not again when the same painted layer was found in a different color glyph (#274).
• Group all the shapes shared by multiple glyphs in the top-level <defs/> element, as Adobe apps don't like direct <use> references between different SVG glyphs (#264, #277). This affects --color_format=picosvg only.
• Use ccmp as default feature for GSUB ligature substitution instead of rlig, as it's more widely supported/enabled (Noto Color Emoji does the same) (#280).

v0.8.0

• Fixed scaling/positioning for --color_format=untouchedsvg output (#267)
• Handle extra whitespace when parsing colors from fill attribute (#269)
• Bump minimum picosvg >= 0.15.0.

  https://github.com/googlefonts/picosvg/releases/tag/v0.15.0
  Notable changes:
  • Added support for gradient templates with xlink:href attibute,
  • Added partial support for nested <svg> elements.

v0.7.1

Pre-apply translation when mapping to/from SVG/font space; fixes struct.error when compiling some SVGs created with Figma (#243, #262)

v0.7.0

• Support configuring absl.logging verbosity from CLI via -v flag (#242).
• Added config/CLI options to configure ascender, descender and apply a user-defined transform to all glyphs (#250).
• Added --version_major and --version_minor options to set the font version (#251).
• Compute the actual bounding box when drawing invisible points defining the color base glyph extents (#252).
• Set default advance width to the same as NotoColorEmoji.ttf (slightly larger than the glyph height)
• Scale glyph height to fit (ascender - descender), center horizontally within default advance width, preserving original aspect ratio; stretch glyph advance width if the viewbox is not square (w > h) (#255).
• Add option to customize the --linegap (set to 0 by default like NotoColorEmoji) (#258).
• Fixed bugs when running nanoemoji on Windows native Python. Also run continuous testing on Windows CI runner (#240).

v0.6.0

• When layers exceed 255, build a 255-ary tree of PaintColrLayers instead
  of less efficient binary tree of PaintComposite (#225).
• Don't error when SVG attributes contain empty string (#229).
• Redefined PaintLinearGradient's P2 as "normal" vector, equivalent to
  P1 rotated 90 degrees, following latest COLRv1 draft spec (#236).
• Paint format numbers re-numbered following introduction of new formats
  in fonttools and draft spec (#234)

Bump minimum requirements:

• picosvg >= 0.11.1
• fonttools >= 4.20.0

v0.5.2

Fix bug with --ignore_reuse_error not passing around properly

v0.5.1

Update to match latest spec

v0.5.0

• Restored nanoemoji.write_glyphgraph to working order (#219).
• Make clipping to viewbox faster by parallelizing it through picosvg and ninja (#221).
• Re-add CLI flags that were removed when the --config option was introduced in v0.4.1. CLI flags take precedence over settings from config file (#222).
• Bump requirements:
  • picosvg >= 0.9.1
  • fonttools >= 4.18.1

v0.4.2

Switch to github CI
