Opaque and Opacity (setting)
The setting Opaque and the Opacity define the level of translucency of graphical objects shown.
An opaque Object is not translucent. It fully obscures objects located behind it.
When the switch Opaque is turned off, one can set the partial opacity / transparency of the respective object. The value of opacity is in the range of 0 to 1:
When the value within an interval is chosen (e.g. 0.3) the particular object ist still visible, but thanks to its transparency (translucency) does not obscure nor hide object behind it allowing them to be visible also.
The setting is available for following evaluations:
Remark: The opacity will be automatically set to 0.1 when the user unchecks the Opaque-switch while the original opacity value was left at 1.0 - this provides transparent visualization immediately after the user requests transparency (but has left the opacity value at 1.0).
