下面是一个完整的示例代码,展示了如何使用color_palette_formats
插件来读取和写入不同格式的颜色调色板文件。
import 'dart:io';
import 'package:color_palette_formats/color_palette_formats.dart';
void main() {
// 读取Adobe Color Book (acB) 文件
final acbFile = File('path/to/acb1_v1.acb');
final ac = AdobeColorBook.fromBytes(acFile.readAsBytesSync());
assert(ac.version == supportedAdobeColorBookVersion);
assert(ac.colors.length == 300);
// 读取Adobe Color Swatch (aco) 文件
final acoFile = File('path/to/aco1_v1.aco');
final aco = AdobeColorSwatch.fromBytes(acoFile.readAsBytesSync());
assert(aco.version == supportedAdobeColorSwatchVersion);
assert(aco.colors.length == 52);
// 读取Adobe Color Table (act) 文件
final actFile = File('path/to/act1.act');
final act = AdobeColorTable.fromBytes(actFile.readAsBytesSync());
assert(act.colors.length == adobeColorTableColorsCount);
// 读取Adobe Swatch Exchange (ase) 文件
final aseFile = File('path/to/ase1_v1.ase');
final ase = AdobeSwatchExchange.fromBytes(aseFile.readAsBytesSync());
assert(ase.version == supportedAdobeSwatchExchangeVersion);
assert(ase.colors.length == 122);
// 读取GIMP Palette (gpl) 文件
final gplFile = File('path/to/gplv.gimp');
final gpl = GimpPalette.fromBytes(gplFile.readAsBytesSync());
assert(gpl.name == 'Visibone2');
assert(gpl.colors.length == 256);
// 读取Homesite Palette (hpl) 文件
final hplFile = File('path/to/hplv.hpl');
final hpl = HomesitePalette.fromBytes(hlFile.readAsBytesSync());
assert(hpl.version == supportedHomesitePaletteVersion);
assert(hpl.colors.length == 287);
// 读取JASC Palette (pal) 文件
final palFile = File('path/to/palv.pal');
final pal = JascPalette.fromBytes(palFile.readAsBytesSync());
assert(pal.version == supportedJascPaletteVersion);
assert(pal.colors.length == 3);
// 读取Paint.NET Palette 文件
final paintDotNetFile = File('path/to/paint-dot-net.txt');
final paintDotNet = PaintDotNetPalette.fromBytes(paintDotNetFile.readAsBytesSync());
assert(paintDotNet.colors.length == 96);
// 读取Procreate Swatches 文件
final procreateFile = File('path/to/procreate1.swatches');
final procreate = decodeProcreateSwatches(procreateFile.readAsBytesSync());
assert(procreate.first.swatches.length == 30);
// 读取Resource Interchange File Format (riFF) Palette 文件
final riffFile = File('path/to/riffv_pal');
final riff = ResourceInterchangeFileFormat.fromBytes(riffFile.readAsBytesSync());
assert(riff.version == supportedResourceInterchangeFileFormatVersion);
assert(riff.colors.length == 16);
// 读取Sketch Palette 文件
final sketchpaletteFile = File('path/to/sketchpalette1sketchpalette');
final sketchpalette = SketchPalette.fromBytes(sketchpaletteFile.readAsBytesSync());
assert(sketchpalette.compatibleVersion == supportedSketchPaletteVersion);
assert(sketchpalette.pluginVersion == supportedSketchPaletteVersion);
assert(sketchpalette.colors.length == 6);
}
