Hi Andrei,

Thanks for the help. It was a lot of help for me.

This is what is am using as of now and have tried many combinations with both the filter.

var matrix:Array = new Array();
            matrix=matrix.concat([.5,.5,0,.5,0]);// red
            matrix=matrix.concat([.5,.5,0,.5,0]);// green
            matrix=matrix.concat([.5,.5,0,.5,0]);// blue
            matrix=matrix.concat([0,0,0,.5,0]);// alpha
            var my_filter:ColorMatrixFilter=new ColorMatrixFilter(matrix);


            var filters:Array = new Array();        
            var cf:ConvolutionFilter = new ConvolutionFilter(3,3,new Array(-2,-1,0,-1,1,1,0,1,1),0); 
           
            filters.push( cf ); 
            filters.push( my_filter ); 
            m_output.filters = filters;

the attached image shows the current and required output. not sure how to get the required effect. if you can sugest something on this it would be of great help.

Thanks,

Ayush

I think part of your problem is changing the alpha to .5 - you just need to do a proper grayscale first. Then do the convolution. I think this should get you a bit closer:

var greyScale:Array = [.33, .33, .33, 0, 0, .33, .33, .33, 0, 0, .33, .33, .33, 0, 0, .33, .33, .33, 1, 0];

var cmf:ColorMatrixFilter = new ColorMatrixFilter(greyScale);

var cf:ConvolutionFilter = new ConvolutionFilter(3,3,new Array(1,1,0,-1,1,1,-1,-1,-1),1,100);

m_output.filters = [cmf, cf];

Note the bias of 100 in the convolution filter.
