The code looks like that the selection is just used to define the center. I propose to respect the selection size too (see radiusX/Y)

void Render(Surface dst, Surface src, Rectangle rect)
{
    Rectangle selection = EnvironmentParameters.GetSelection(src.Bounds).GetBoundsInt();
    float CenterX = ((selection.Right - selection.Left) / 2)+selection.Left;
    float CenterY= ((selection.Bottom - selection.Top) / 2)+selection.Top;
    float radiusX = CenterX - selection.Left;
    float radiusY = CenterY - selection.Top;
 
    float offx=0,offy=0;
    ColorBgra CurrentPixel;
    for (float y = rect.Top; y < rect.Bottom; y++)
    {
        for (float x = rect.Left; x < rect.Right; x++)
        {
            float nx  = (x - CenterX);
            float ny  = (y - CenterY);
            
            nx /= radiusX * (float)Amount4/50;
            ny /= radiusY * (float) Amount5/50;
            
            offx = nx / (float)Math.Sqrt(1 -  Amount1 * (ny * ny))* radiusX * (float)Amount2 + CenterX;
            offy = ny / (float)Math.Sqrt(1 -  Amount1 * (nx * nx))* radiusY * (float)Amount3 + CenterY;
            
 
            CurrentPixel = src.GetBilinearSample((float)offx,(float)offy);
            dst[(int)x,(int)y]=CurrentPixel;
 
        }
    }
 
}

That sounds like a good idea - threw this together to answer a forum question to create a bands Kick Drum Logo - hence the name Drum Skin

OH ................... I only just noticed this Plugin - late to the party again.  What a great result ..... I love it!  I got one of my cats to be the model

Fashionably late, Pixey

I guess you are one of the guys who can imagine the math. It's just more than some formulas.

It took me a small while to figure out that the center variable is used as a point and as a distance. This was the confusing part of the algorithm.

But as you said, a quick hack.

Thank You!!

 

Some people will look how to bulge text. This effect can give text or shapes a bulge effect. This is how I did it: 

 

1. Type your text.

2. Center the text

3. Use TR's and EER's Drum Skin effect.

 

By the way, The rugby ball was just a rectangle. I did the same thing as above.
