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 = AdobeColorSwatch.fromBytes(acoFile.readAsBytesSync());
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.readAsBytesSync());
assert(procreate.first.swatches.length == 30);
// Example: Reading a Sketch Palette file.
final sketchpaletteFile = File('path/to/sketchpalette1_v1.4.sketchpalette');
final sketchpalette = SketchPalette.fromBytes(sketchpaletteFile.readAsBytesSync());
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');
aseFile.writeAsBytesSync(ase.toBytes());
