Color palette formats

A package for decoding and encoding various color palette formats. It allows Flutter apps to read and write color data across a wide range of industry-standard formats.

Currently, the package supports the following formats:

• Adobe Color Book (ACB)
• Adobe Color Swatch (ACO)
• Adobe Color Table (ACT)
• Adobe Swatch Exchange (ASE)
• GIMP Palette (GPL)
• Homesite Palette (HPL)
• JASC
• Palette (PAL)
• Paint.NET Palette
• Procreate Swatches
• Resource Interchange File Format (RIFF)
• Sketch Palette

Examples

Reading a color palette file

// Example: Reading an ACO (Adobe Color Swatch) file.
final acoFile = File('path/to/aco1_v1.aco');
final aco = decodeAdobeColorSwatch(acoFile);
assert(aco.version == supportedAdobeColorSwatchVersion);
assert(aco.colors.length == 52);

// Example: Reading a Procreate Swatches file.
final procreateFile = File('path/to/procreate1.swatches');
final procreate = decodeProcreateSwatches(procreateFile);
assert(procreate.first.swatches.length == 30);

// Example: Reading a Sketch Palette file.
final sketchpaletteFile =  File('path/to/sketchpalette1_v1.4.sketchpalette');
final sketchpalette = decodeSketchPalette(sketchpaletteFile);
assert(sketchpalette.compatibleVersion == supportedSketchPaletteVersion);
assert(sketchpalette.pluginVersion == supportedSketchPaletteVersion);
assert(sketchpalette.colors.length == 6);

Writing a color palette file

final ase = AdobeSwatchExchange(
  version: supportedAdobeSwatchExchangeVersion,
  colors: [
    AdobeSwatchExchangeColor(
      name: 'red',
      model: AdobeSwatchExchangeColorModel.rgb,
      values: [1, 0, 0],
    ),
    AdobeSwatchExchangeColor(
      name: 'cyan',
      model: AdobeSwatchExchangeColorModel.cmyk,
      values: [1, 0, 0, 0],
    ),
    AdobeSwatchExchangeColor(
      name: 'gray',
      model: AdobeSwatchExchangeColorModel.gray,
      values: [0.5],
    ),
  ],
);
// write to file
final aseFile = File('path/to/ase1_v1.ase');
encodeAdobeSwatchExchange(ase, aseFile);
