wic_decode

A Flutter plugin for decoding images on Windows using the Windows Imaging Component (WIC).

Features

• Decode an image file to raw RGBA pixels via decodeImageToRawPixelFile.
• Read the decoded image's EXIF/XMP/WIC orientation (1–8, defaults to 1).
• Decode the resulting raw pixel file into a dart:ui.Image with decodeRawPixelFileToUIImage.
• Display an image with orientation applied using WicDecode.buildImageViewFromUIImage.

Usage

import 'package:flutter/widgets.dart';
import 'package:wic_decode/wic_decode.dart';

final plugin = WicDecode();

final result = await plugin.decodeImageToRawPixelFile(
  srcImage: 'input.jpg',
  destFile: 'output.raw',
);

final image = await plugin.decodeRawPixelFileToUIImage(
  filePath: 'output.raw',
  width: result.width,
  height: result.height,
);

// Apply EXIF orientation when displaying:
WicDecode.buildImageViewFromUIImage(image, result.orientation);

result exposes:

• result.width — output image width
• result.height — output image height
• result.orientation — EXIF/XMP orientation (1–8), defaults to 1

Platform support

• Windows only.
