Recommended Posts

A slightly different take on the sketch plugin.
You will find it in the Menu: Effects - > Artistic
Version 1.1 uploaded 10:15 PM Wednesday, June 12, 2013 (UTC) - Noise Filter Implemented
The Code:


Hidden Content:
// Submenu: Artistic
// Name: Line Tracer
// Title: Line Tracer - v1.0
// Author: TechnoRobbo
// URL: http://www.technorobbo
#region UICode
int Amount1 = 3; // [1,7] Line Width
int Amount2 = 4;// [1,10] Threshold
int Amount3 = 20;// [0,50] Color

void Render(Surface dst, Surface src, Rectangle rect)
    ColorBgra CP;
    ColorBgra CO;
    ColorBgra CO2;
    ColorBgra H2O;
    int tmp =0;
    int tmp2 =0;
    for (int y = rect.Top; y < rect.Bottom; y++)
        for (int x = rect.Left; x < rect.Right; x++)
            CP = src[x,y];
            CO = src.GetBilinearSampleClamped(x-Amount1,y-Amount1);  
            CO2 = src.GetBilinearSampleClamped(x-Amount1,y); 
            H2O = src.GetBilinearSampleClamped(x,y-Amount1); 
            HsvColor hsv = HsvColor.FromColor(CP.ToColor());
            HsvColor hsv2 = HsvColor.FromColor(CO.ToColor());
            HsvColor hsv3 = HsvColor.FromColor(CO2.ToColor());
            HsvColor hsv4 = HsvColor.FromColor(H2O.ToColor());
            int H = hsv.Hue ; 
            int S = Amount3 * hsv.Saturation/100 ;
            int V = Math.Abs(hsv.Value-hsv2.Value);
            tmp = Math.Abs(hsv.Value-hsv3.Value);
            tmp2 = Math.Abs(hsv.Value-hsv4.Value);
            if (V < Amount2 && tmp < Amount2 && tmp2 < Amount2){
            } else {
            hsv = new HsvColor(H,S,V);

            ColorBgra NP = ColorBgra.FromColor(hsv.ToColor());
            NP.A = CP.A;  

            dst[x,y] = NP;

There's a typo in the script. You're setting "tmp" twice in a row. I'm thinking the second one should be "tmp2".

Also, hsv3 and hsv4 are being set from the same color sample?

Hope this helps.
