Build COLR table from color layers mapping.
- Parameters
colorGlyphs – map of base glyph name to, either list of (layer glyph name, color palette index) tuples for COLRv0; or a single
Paint
(dict) or list ofPaint
for COLRv1.version – the version of COLR table. If None, the version is determined by the presence of COLRv1 paints or variation data (varStore), which require version 1; otherwise, if all base glyphs use only simple color layers, version 0 is used.
glyphMap – a map from glyph names to glyph indices, as returned from TTFont.getReverseGlyphMap(), to optionally sort base records by GID.
varStore – Optional ItemVarationStore for deltas associated with v1 layer.
varIndexMap – Optional DeltaSetIndexMap for deltas associated with v1 layer.
clipBoxes – Optional map of base glyph name to clip box 4- or 5-tuples: (xMin, yMin, xMax, yMax) or (xMin, yMin, xMax, yMax, varIndexBase).
- Returns
A new COLR table.
- fontTools.colorLib.builder.buildCPAL(palettes: Sequence[Sequence[Tuple[float, float, float, float]]], paletteTypes: Optional[Sequence[ColorPaletteType]] = None, paletteLabels: Optional[Sequence[Union[None, str, Dict[str, str]]]] = None, paletteEntryLabels: Optional[Sequence[Union[None, str, Dict[str, str]]]] = None, nameTable: Optional[table__n_a_m_e] = None) table_C_P_A_L_ [source]
Build CPAL table from list of color palettes.
- Parameters
palettes – list of lists of colors encoded as tuples of (R, G, B, A) floats in the range [0..1].
paletteTypes – optional list of ColorPaletteType, one for each palette.
paletteLabels – optional list of palette labels. Each lable can be either: None (no label), a string (for for default English labels), or a localized string (as a dict keyed with BCP47 language codes).
paletteEntryLabels – optional list of palette entry labels, one for each palette entry (see paletteLabels).
nameTable – optional name table where to store palette and palette entry labels. Required if either paletteLabels or paletteEntryLabels is set.
- Returns
A new CPAL v0 or v1 table, if custom palette types or labels are specified.
- fontTools.colorLib.builder.populateCOLRv0(table: COLR, colorGlyphsV0: Dict[str, Sequence[Tuple[str, int]]], glyphMap: Optional[Mapping[str, int]] = None)[source]
Build v0 color layers and add to existing COLR table.
- Parameters
table – a raw
otTables.COLR()
object (not ttLib’stable_C_O_L_R_
).colorGlyphsV0 – map of base glyph names to lists of (layer glyph names, color palette index) tuples. Can be empty.
glyphMap – a map from glyph names to glyph indices, as returned from
TTFont.getReverseGlyphMap()
, to optionally sort base records by GID.
