map - Brightness of chartplotter (Dynamic Data Display) C# -

i'm using microsoft visual studio 2010, including reference dynamic info display. i'm want create scroll bar command of brightness of map . i'm tried find property brightness or without success. give thanks help friends. :)

you can command brightness of plotter setting background different rgb values. each value has range 0 (darkest) 255 (brightest). first set brightest color, illustration

byte r = 255; byte g = 255; byte b = 255;

and define factor (range 0.5 1.0) controlled slider.(0.0 total blackness, set lower range 0.5 gray).

double minfactor = 0.5; double maxfactor = 1.0; double factor = maxfactor; //initially, brightest

then background of plotter

color color = color.fromrgb((byte)(factor*r), (byte)(factor*g), (byte)(factor*b)); plotter.background = new solidcolorbrush(color);

and how slider controls brightness.

slider slider = new slider(); slider.value = factor; slider.maximum = maxfactor; slider.minimum = minfactor; slider.valuechanged += (s, e) => { var newfactor = e.newvalue; color newcolor = color.fromrgb((byte)(newfactor * r), (byte)(newfactor * g), (byte)(newfactor * b)); plotter.background = new solidcolorbrush(newcolor); };

brightness of map

a. set dark background plotter

plotter.background = new solidcolorbrush(colors.black);

b. hide grid

plotter.axisgrid.visibility = system.windows.visibility.collapsed;

c. adjust map's opacity slider

slider.valuechanged += (s, e) => { var newfactor = e.newvalue; map.opacity = newfactor; //color newcolor = color.fromrgb((byte)(newfactor * r), (byte)(newfactor * g), (byte)(newfactor * b)); //plotter.background = new solidcolorbrush(newcolor); }
