Hi guys.
I am receiving a Yuv420 buffer as a Uint8Array. I want to render this as Image data with vtk.js i.e
const values = yuv420Buffer
var scalars = vtkDataArray.newInstance({
values: values,
numberOfComponents: 4, // number of channels
dataType: VtkDataTypes.UNSIGNED_CHAR, // values encoding
name: 'scalars'
});
var imageData = vtkImageData.newInstance();
imageData.setOrigin(0, 0, 0);
imageData.setSpacing(1.0, (width / height).toFixed(2), (width / depth).toFixed(2));
imageData.setExtent(0, width - 1, 0, height - 1, 0, depth - 1);
imageData.getPointData().setScalars(scalars);
Do I need to convert the Yuv420 buffer into an RGBA buffer first? If so, is there an easy way to do this in javascript?
Any help would be greatly appreciated
