A background color for the visualizer.
property BackgroundColor: TRVColor;
property BackgroundOpacity: TRVOpacity;
Background color is used to fill space "below" the bar.
Opacity is defined in 1/1000 of percent, it must be in the range 0..100000. Opacity is used only if visualizers are drawn using GDI+ (in Delphi XE2+).
Example (BackgroundColor = clMoneyGreen):
You can see that the background area has the same width as the bar. Margins are not filled with background.
Default value
•BackgroundColor: rvclNone (no background)
•BackgroundOpacity: 50000 (i.e. 50%), ignored for BackgroundColor = rvclNone
