Thanks again, @matt.mccormick. The example link you provided me helped me a ton and i’m up and running.

Great!

Is there a way to pass an Arraybuffer (preferably as 16-bit and not 8-bit) to ITK based C++ code. In the example you provided, the input image to C++ is read from the disk. In my application, this file is read on the browser side using UTIF and I have access just to the Arraybuffer from UTIF’s reader. Do you have any examples for extracting pixel intensities from that arraybuffer and passing it to the C++ code?

In this case, you can create an itk/Image with something like:

const dimension = 2
const componentType = itk.IntTypes.UInt8
# possibly also specify the pixelType and numberOfComponents
const imageType = new itk.ImageType(dimension, componentType)
const image = new itk.Image(imageType)
image.size = [width, height]
image.data = new Uint8Array(arrayBuffer)

Then, pass the image to runPipelineBrowser.
