HELP! Polar To Rect Conversion (In Codelab)

[El Sid]

I'm Trying To Make This Work.

int Amount1=0;	//[0,100]Slider 1 Description
int Amount2=0;	//[0,100]Slider 2 Description
int Amount3=0;	//[0,100]Slider 3 Description

void Render(Surface dst, Surface src, Rectangle rect)
{
   PdnRegion selectionRegion = EnvironmentParameters.GetSelection(src.Bounds);
   Surface dst = dstArgs.Surface;
   Rectangle selection = this.EnvironmentParameters.GetSelection(src.Bounds).GetBoundsInt();

   long CenterX = (long)(((selection.Right - selection.Left) / 2)+selection.Left);
   long CenterY = (long)(((selection.Bottom - selection.Top) / 2)+selection.Top);

   for(int y = rect.Top; y < rect.Bottom; y++)
   {
       for (int x = rect.Left; x < rect.Right; x++)
       {
       	double r = System.Math.Sqrt(x * x + y * y);
	dst[x,y] = src[r, CenterY];
       }
   }
}

Basically It Move Pixels To The Center And Then Moving Them Right Based On The Radius Value, If I Knew How To Move The Pixels Then I Could Easily Finish It (And Make The Pixels On The Left Go To The Left As Well) So Yeah. Any Help Would Be Appreciated.

Okay, I got it. You weren't thinking in the right direction

int Amount1=0;   //[0,100]Slider 1 Description
int Amount2=0;   //[0,100]Slider 2 Description
int Amount3=0;   //[0,100]Slider 3 Description

void Render(Surface dst, Surface src, Rectangle rect)
{
   Rectangle selection = this.EnvironmentParameters.GetSelection(src.Bounds).GetBoundsInt();
   float width = dst.Bounds.Right - dst.Bounds.Left;
   long CenterX = (long)(((selection.Right - selection.Left) / 2)+selection.Left);
   long CenterY = (long)(((selection.Bottom - selection.Top) / 2)+selection.Top);
   float r, theta, offx, offy, setx, sety;
   for(int y = rect.Top; y < rect.Bottom; y++)
   {
       for (int x = rect.Left; x < rect.Right; x++)
       {
           r = y/2;
           theta = (float)((System.Math.PI*2)*(x/width));
           offx = (float)(r*System.Math.Cos(theta));
           offy = (float)(r*System.Math.Sin(theta));
           setx = (float)(CenterX+offx);
           sety = (float)(CenterY-offy);
           dst[x,y] = src.GetBilinearSample(setx, sety);
       }
   }
}

It's actually rather simple.

Haha, Nice One Illnab. Very Good. (Not Perfect But Meh)

[Illnab1024]

Not Perfect how? rect to polar consumes a looooot of quality from the image (y row is just a little better than half quality, x row is worse at the top and better at the bottom)

[El Sid]

I Don't Expect You To Get It Perfect BTW, But Much Thanks For It.

Steps For Unpefrectness:

1. New 400x400 Image

2. Make New Layer

3. Horizontal Line With Width Of 20 in middle

4. run rect to polar

5. run codelab script

It's Still Pretty **** Good In My Opinion.

That's just a quality issue.
