Replace all instance of single color

[jgreywolf]

Need some help changing pixel colors on SKBitmap images in my app. I am using ColorTable functionality right now, but it changes all pixels to be the new color, and I only want a specific color replaced.

`var targetColor = color;

    var tableRed = new byte[256];
    var tableGreen = new byte[256];
    var tableBlue = new byte[256];

    for (int i = 0; i < 256; i++)
    {
        tableRed[i] = targetColor.Red;
        tableGreen[i] = targetColor.Green;
        tableBlue[i] = targetColor.Blue;
    }

    paint.ColorFilter =
        SKColorFilter.CreateTable(null, tableRed, tableGreen, tableBlue);

    canvas.DrawBitmap(Image,new SKPoint( drawX, drawY), paint);`

How can I best achieve this?
