In which file the dicom files are read and showed in Canvas?

[gdet]

Hello, sorry to ask again but I made an error and wrote to "dwv" issues. Can you point me to dwv-jqui files for reading dicom files and showing them to the canvas?

Thank you very much

dwv was the good place for your question! dwv-jqui uses dwv to parse the dicom files. dwv-jqui is just the frontend.

Ok thank you! So a final and silly question... I have installed dvw-jqui and everything is working (as I can tell). Should I also install dvw to have a fully working local tool? Or dvw files are included in dvw-jqui? And if they are included in which folder they are (I cannot find them in src etc).

If you are using the release package, dwv is included and can be found in the node_modules folder (the place for the dependencies).

thank you! you are very helpful!!

Hello and sorry to bother you again. I tried to look for the files and code that you suggested in the other thread but I cannot find it in node modules or anywhere in the code. I would like to get somehow the local dicom files path or maybe the images because I would like to run machine learning code which uses your state.json and the dicom files. Since it is a browser I cannot get the full path of the files when they load (for security reasons). I tried to find how you load the dicom to images and the closest I got was to print ImageData { width: 98, height: 10, data: Uint8ClampedArray(3920) } in colourMap.js but I am not sure if this is the correct path to follow. Could I somehow get the dicom local paths? Or maybe if this is not possible to download all images created from the dicom files?

[ivmartel]

The dicom files are either loaded from your local machine or from a url you provide to the viewer, this will give you their path. The viewer loads the dicom file via a 'loader' (see the io folder), for example the urls loader uses an XMLHttpRequest. Once loaded, the file is parsed in the dicom/dicomParser.js to extract its information. Meta data is stored as an object and the image as a dwv.image.Image object (see image/image.js). This image is accessible from the load events sent during the load or via the app class, see app.getImage() (here).

(all this happens in the dwv library)

Thank you for your detailed answer. But I cannot find any of these files in dwv-jqui or the code. I have also looked at node_modules. Have I done something wrong in the installation? I followed the instructions of dwv-jqui and it seems to work correctly though. This is how my files are:

The files are in the separate dwv repository: https://github.com/ivmartel/dwv
