Text Objects can be displayed as #UNC text, or as the text overlaid with a dithered pattern if the "display value" expression has “uncertain” quality.
This setting allows switching between these two modes. This type of indication is active only when IgnoreValueQuality = 2.
0 –Show the result of the "display value" expression overlaid with a dithered pattern.
1 – Show “#” followed by text defined by [Page] UncertainText (default value: “UNC”)
Default Value: 1
