Hi Ganaraj, Thanks for replying.
Your solution seems more better. Please provide me the complete example if you can. And again, suppose i want to get the color(change) dynamically, suppose from a colorpicker selected value, how I will set for colortransform?(Means, var ct:ColorTransform = new ColorTransform (1,1,1,1,A,B,C,D); How will i set the values of var. A,B,C,D dynamically? ) Thanks, Paritosh On Feb 14, 10:57 am, ganaraj p r <[email protected]> wrote: > If all you need to do is change the color ( and dont need to retrieve the > values) then > This peice of code will change the color of the graphics you have drawn in > uicomp from any color to red. > > var ct:ColorTransform = new ColorTransform(1,1,1,1,255,-255,-255,0); > uicomp.transform.colorTransform = ct; > > To change from any color to green: > > var ct:ColorTransform = new ColorTransform(1,1,1,1,-255,255,-255,0); > uicomp.transform.colorTransform = ct; > > Any color to blue: > var ct:ColorTransform = new ColorTransform(1,1,1,1,-255,-255,255,0); > uicomp.transform.colorTransform = ct; > > I could also provide a complete example if you want. > > On Fri, Feb 13, 2009 at 6:22 PM, Paritosh Bisi <[email protected]>wrote: > > > > > > > Thanks Kalpesh for the codes, > > > But my requirement is somewhat different. > > See, I have a canvas.
