[Bug] Progressive loading Issue

[devkumarsingh-qure]

Describe the Bug

Getting warning:
WebGL: INVALID_OPERATION: texSubImage3D: ArrayBufferView not big enough for request in vtkStreamingOpenGLTexture.js

for below code:

This is happening for images which are thumbnails or fetched from byte range requests, basically partial images as the warning message suggests. I have tried scaling the pixel data in my local setup and that seems to be working but I am not sure if it's the correct way to do it.

Steps to Reproduce

It is happening for cornerstone3D progressive loading examples (as of 3rd feb 2025, the dicom links seem to be broken). Alternatively, setup a project which supports progressive loading with cornerstone3D.

The current behavior

As it throws a warning message for partial images, It is showing a gray viewport.

The expected behavior

Pixelated images should be shown for partial images
