ID 390403 - The Pixel Analyzer displays incorrect values when using BIT data and comparing it to the Viewer channel data.

Follow

Problem summary:
The Pixel Analyzer displays incorrect values when using BIT data and comparing it to the Viewer channel data.

 

Customer reported version:
nuke.10.5v3

 

Customer reported platform:
centos7

 

Steps to reproduce:

1) In Nuke, create a Constant node and connect the Viewer.

2) Set the color values to R 1 | G 0.5 | B 0.25

3) Right-click the Properties bin panel and select Pixel Analyzer.

4) CTRL+Click the Viewer for capturing a color.

5) In the Pixel Analyzer bin, select the dropdown for 'range' and choose 8 bit

6) In the Viewer, select the 2d  image information arrow for - 8 bit.

7) Compare the results of the Constant values between the Viewer and the Pixel Analyzer data.

 

Expected behavior:
The same values should appear for the 8-bit values when comparing the Viewer data to the Pixel Analyzer data. 

 

Actual behavior:
Currently, the Viewer appears correct with data and the Pixel Analyzer has incorrect data. The Pixel Analyzer in Nuke (when switched to range: 8 bit), samples the value range 0 to 218.

Previous to version 9.0v1, the Viewer displayed the same range that is currently in the Pixel Analyzer.

 

Workaround:
No workaround is available at this time.
