Describe the Bug

I encountered issue below. Any help is appreciated.

"@cornerstonejs/calculate-suv": "^1.0.3", "@cornerstonejs/core": "1.11.1", "@cornerstonejs/streaming-image-volume-loader": "1.11.1", "@cornerstonejs/tools": "1.11.1", "@cornerstonejs/dicom-image-loader": "1.11.1", " node": "14.18.0"

Steps to Reproduce

import dicomParser from 'dicom-parser' import * as cornerstone from '@cornerstonejs/core' import cornerstoneDICOMImageLoader from '@cornerstonejs/dicom-image-loader' export default function initCornerstoneDICOMImageLoader() { if (!cornerstoneDICOMImageLoader) return console.log(cornerstoneDICOMImageLoader) cornerstoneDICOMImageLoader.external.cornerstone = cornerstone cornerstoneDICOMImageLoader.external.dicomParser = dicomParser cornerstoneDICOMImageLoader.configure({ useWebWorkers: false, decodeConfig: { convertFloatPixelDataToInt: false } }) if (cornerstoneDICOMImageLoader.webWorkerManager.isInitialized) { let maxWebWorkers = 1

if (navigator.hardwareConcurrency) {
  maxWebWorkers = Math.min(navigator.hardwareConcurrency, 7)
}
var config = {
  maxWebWorkers,
  startWebWorkersOnDemand: false,
  taskConfiguration: {
    decodeTask: {
      initializeCodecsOnStartup: false,
      strict: false
    }
  }
}
cornerstoneDICOMImageLoader.webWorkerManager.initialize(config)

} }

I updated the version to 1.14.4 and I get the same error!

Your cornerstonejs is version 1.11.1, have update new version.

It has to be like this import * as libCornerstoneDicomImageLoader from '@cornerstonejs/dicom-image-loader';

Here is my code example

import * as libCornerstone from '@cornerstonejs/core';
import * as libCornerstoneDicomImageLoader from '@cornerstonejs/dicom-image-loader';
import libDicomParser from 'dicom-parser';

/**
 * Init
 * @returns {undefined}
 */
function init() {

    libCornerstoneDicomImageLoader.external.cornerstone = libCornerstone;
    libCornerstoneDicomImageLoader.external.dicomParser = libDicomParser;

    libCornerstoneDicomImageLoader.configure({
        useWebWorkers: true,
        decodeConfig: {
            convertFloatPixelDataToInt: false
        }
    });

    let maxWebWorkers = 1;

    if (navigator.hardwareConcurrency) {
        maxWebWorkers = Math.min(navigator.hardwareConcurrency, 7);
    }

    libCornerstoneDicomImageLoader.webWorkerManager.initialize({
        maxWebWorkers,
        startWebWorkersOnDemand: false,
        taskConfiguration: {
            decodeTask: {
                initializeCodecsOnStartup: false,
                strict: false
            }
        }
    });
}

// Export
export {
    init
};

I've got a new problem. @jlopes90

[jlopes90]

This is not enough. You have to see the code where this problem "require".
