Detailed Description

pqColorOpacityEditorWidget provides an in-line editor widget for editing the color and opacity transfer functions.

The property group is expected to have properties with the following functions. If any of the optional properties are missing, then the corresponding widgets are hidden.

"XRGBPoints" :- property with (x,r,g,b) tuples that is controlled by a color-transfer function editor (pqTransferFunctionWidget).
"ScalarOpacityFunction" :- (optional) proxy-property referring to a proxy with "Points" property with (x,a,m,s) tuples that is controlled by an opacity-transfer function editor (pqTransferFunctionWidget).
"EnableOpacityMapping" :- (optional) property used to enable opacity mapping for surfaces. Controlled by a checkbox in the Widget.
"UseLogScale" :- (optional) property used to enable/disable log mapping for colors.
"UseLogScaleOpacity" :- (optional) property used to enable/disable log mapping for opacity.
"UseOpacityControlPointsFreehandDrawing" :- (optional) property used to enable/disable freehand drawing for positioning control points
"Transfer2DBoxes" :- (optional) property with (x0, y0, width, height, r, g, b, a) tuples that is controlled by the 2D transfer function editor (pqTransferFunction2DWidget). Caveats:
Opacity editor:- pqColorOpacityEditorWidget shows an opacity editor widget. Typically, opacity function is optional and used only when "EnableOpacityMapping" is property is ON. However, in cases of Volume rendering, the EnableOpacityMapping has no effect.
