I make an api call to append the headers for CORS, but the loadImage function fails. Tried loading this image: https://phpapi.rsna.org/image-viewer/v1/get/image?image-address=https://pubs.rsna.org/na101/home/literatum/publisher/rsna/journals/content/radiographics/2018/rg.2018.38.issue-1/rg.2018170120/20171226/images/large/rg.2018170120.fig1a.jpeg in our code, and on the example site: https://rawgit.com/cornerstonejs/cornerstoneWebImageLoader/master/examples/index.html, but it doesn't work even though it works in older version of the code in an example shown here: http://images.rsna.org/index.html?doi=10.1148/rg.2018170120&fig=fig1a

Potential Enhancement.

It's possible to load metaData for images without doing so directly during image loading. You can see an example of this with the wadors metaDataProvider. Knowing that, would it be worth checking if metaData exists for the imageId when its created? Similar to how we do in the WadoImageLoader?

https://github.com/chafey/cornerstoneWADOImageLoader/blob/2b949ef45adf72edca59e99ff93dbd90b4f58565/src/imageLoader/createImage.js#L44-L48

When using cornerstoneTools with webImageLoader, the error "TypeError: errorLoadingHandler is not a function" is raised.

It looks like that handler is implemented in WADOImageLoader but not in WebImageLoader.

Hello,

I am unable to set Authorization headers, as the images which are fetched are secured and giving 401.

Thanks
Gaurav

In both cornerstoneWebImageLoader and cornerstoneWADOImageLoader I'm getting the same error while setting xhr.reponseType (line 116 of cornerstoneWebImageLoader.js).

This can be easily reproduced using the example: http://chafey.github.io/cornerstoneWebImageLoader/

The error is documented here:
https://connect.microsoft.com/IE/feedback/details/795580/ie11-xmlhttprequest-incorrectly-throws-invalidstateerror-when-setting-responsetype

I'm trying to workaround this, but if you find a solution please post here or update head.

it no longer matches a GH release

Is this link active? when I load i get a 404
https://raw.githubusercontent.com/cornerstonejs/cornerstoneWebImageLoader/master/dist/cornerstoneWebImageLoader.js

when I load the same image by using wado and web（Images were converted from DICOM to JPG in the back end）,In webload mode, an error occurred in WWWC,The display did not reach the correct value。
var viewport = cornerstone.getViewport(dt); viewport.voi.windowWidth = 1200; viewport.voi.windowCenter = -600; cornerstone.setViewport(dt,viewport);

I I tried to add tag information, but he hasn't changed a bit. Can you give me some advice?

image.sopInstUID=localData.series[seriesId].imgs[iIndex].sopInstUID; image.maxPixelValue=localData.series[seriesId].imgs[iIndex].largestImagePixelValue; image.windowWidth=localData.series[seriesId].imgs[iIndex].windowWidth; image.windowCenter=localData.series[seriesId].imgs[iIndex].windowCenter; image.minPixelValue=localData.series[seriesId].imgs[iIndex].smallestImagePixelValue; image.intercept=localData.series[seriesId].imgs[iIndex].rescaleIntercept; image.FrameofReferenceUID=localData.series[seriesId].imgs[iIndex].FrameofReferenceUID; image.Rows=localData.series[seriesId].imgs[iIndex].Rows; image.columns=localData.series[seriesId].imgs[iIndex].columns; image.ImagePositionPatient=localData.series[seriesId].imgs[iIndex].ImagePositionPatient;
cornerstone.displayImage(dt,image);
Or use this method：
metaDataProvider:function(type, imageId) { if(type === 'imagePlaneModule') { for(var i=0;i<dataHandle.getSerNum();i++) { for(var j=0;j<dataHandle.getImgNum(i);j++) { var img=localData.series[localData.sIdArr[i]].imgs[j]; if(img.imageId===imageId) return img; } } } }
cornerstone.metaData.addProvider(metaDataProvider);

So I am converting a TIFF image to a canvas and then converting that canvas into a PNG. I can display this new PNG on the webpage, but whenever I try to load it with cornerstoneWebImageLoader, I get an error, because it is looking for an imageID.

let img = new Image();
img.src = canvas.toDataURL('image/png'); // img.src = data:image/png;base64,....
cornerstone.loadImage(img).then(image => { 
    // more code 
});  // This is where it blows up.

How can I use this loader to show my PNG?

We should be able to load images from file inputs as we can with the WADO Image Loader.

There's a wrong labeled version and it's updating to an old version of the loader.
'bower install cornerstoneWebImageLoader' gets the 0.7.2 version instead of the latest.

Hello,

Is there a way to apply some filters on the loaded images, for example (Sharpness).
This filter usually implemented using a mathematical method to change the image pixels, using a 3d matrix.

Regards.

when i build a program with the lastest version of cornerstonetools ,the png load fine,but all the tools not work

Now that the dist folder isn't available, links from readme.md do not resolve.

Annoyingly, there's no NPM package for the WADO loader and no dist package for this loader.

I've dug up the last dist/ release to use for now.

metaDataProvider
`if (type === 'imagePlaneModule') {

const imageOrientationPatient = getNumberValues(dataSet, 'x00200037', 6);
const imagePositionPatient = getNumberValues(dataSet, 'x00200032', 3);
const pixelSpacing = getNumberValues(dataSet, 'x00280030', 2);
let columnPixelSpacing = null;
let rowPixelSpacing = null;

if (pixelSpacing) {
  rowPixelSpacing = pixelSpacing[0];
  columnPixelSpacing = pixelSpacing[1];
}

let rowCosines = null;
let columnCosines = null;

if (imageOrientationPatient) {
  rowCosines = [parseFloat(imageOrientationPatient[0]), parseFloat(imageOrientationPatient[1]), parseFloat(imageOrientationPatient[2])];
  columnCosines = [parseFloat(imageOrientationPatient[3]), parseFloat(imageOrientationPatient[4]), parseFloat(imageOrientationPatient[5])];
}

return {
  frameOfReferenceUID: dataSet.string('x00200052'),
  rows: dataSet.uint16('x00280010'),
  columns: dataSet.uint16('x00280011'),
  imageOrientationPatient,
  rowCosines,
  columnCosines,
  imagePositionPatient,
  sliceThickness: dataSet.floatString('x00180050'),
  sliceLocation: dataSet.floatString('x00201041'),
  pixelSpacing,
  rowPixelSpacing,
  columnPixelSpacing
};

}`

if dicom refined. it has pixelspacing or sometimes only has imagePixelSpacing.
naybe can do some compatibility?

Hi, I would like to know how can I define a list of imageIds pointing to relative paths.

For example:

   var imageIds = [
     '/image/1791922.jpg',
     '/image/1791925.jpg',
     '/image/1791928.jpg'
   ];

Breaks with error Error: loadImageFromImageLoader: no image loader for imageId

But if I add http://<IP_OF_SERVER> it loads wonderfully.

Any hint?.

Implementated viewer for JPEG images and tools window level,stack,zoom pan,measurements working fine, but the reference line tool is not working.
The error shown in colsole was ''Updated image not loaded yet" I have attachet it for your references. Please advise

The png can be seen here https://v2.vetology.net/patient-manager/image?id=1100414&id2=5367541

Then if you go to the sample page http://rawgit.com/chafey/cornerstoneWebImageLoader/master/examples/index.html
and load the same issue, when it is added to the canvas, the image can't be recognized any longer

Is there some setting I can change so mages display correctly? See screenshot below:

I believe the documentation is outdated. There does not appear to be a bower.json and grunt does not appear to be included as a local dependency. However, webpack appears as a dependency, and there are a number of NPM scripts.

Image loader was not updating last image id drawn at getLoadImage(); This works when I add lastImageIdDrawn = imageId; at getImageData() when lastImageIdDrawn is different to imageId.

Im trying to make custom colormaps on PNGs work.
Is there an example somewhere?

Missing main tag in package.json requires a more explicit path to use. You can see expected usage versus actual usage below. Here is an example of the tag in cornerstoneWADOImageLoader:

https://github.com/chafey/cornerstoneWADOImageLoader/blob/master/package.json#L15

Expected:

Global
<script src="https://unpkg.com/cornerstone-web-image-loader"></script>

Import
import * as cornerstoneWebImageLoader from 'cornerstone-web-image-loader

Actual:

Global
<script src="https://unpkg.com/[email protected]/dist/cornerstoneWebImageLoader.js"></script>

Import
import * as cornerstoneWebImageLoader from 'cornerstone-web-image-loader/dist/cornerstoneWebImageLoader.js

If I get a 👍, I'll make a quick PR
