Hi everyone,

I have some application that transfert a json file that contains buffer of pixels, image dimension, spacing, origin and type of each pixels (int, unsigned int, etc…). I can’t use a standard format like nrrd, Nifti, etc…

Is it possible to create an Image in javascript from those informations? I didn’t find anything on the examples.

Thank you.

Hello Romain,

Yes, a JavaScript Object can just be created as described here:

Hi there,  
this link you have provided is not working for me. Is there a new location for the docs?

`itk.js` is currently undergoing refactoring, that might be the reason. @matt.mccormick should be back in office next week, he will know where are the old and new docs.
