  • YBR_FULL — YUV color encoding (JPEG-related)

Usage

import 'package:dicom_parser/dicom_parser.dart';
import 'dart:typed_data';

Uint8List? fileBytes;

// Read DICOM file bytes into fileBytes

var dicomParser = DICOMParser();
DICOMModel? dicomModel =
    await dicomParser.parseDICOMFile(fileBytes);
if (dicomModel != null) {
    // Parsed tags from DICOM File
    List<TagModel> tags = dicomModel.tags;
    
    // Parsed Image as Uint8List that can be  used in Image.memory() to view in flutter widget
    Uint8List? parsedImageBytes = dicomModel.imageBytes;
    
    // Get Modality of DICOM File
    String? modality = dicomModel.getModality();
}
