           // CurrentPixel.G = (byte)PrimaryColor.G;
          if(CurrentPixel.R != 255 && CurrentPixel.G != 255 && CurrentPixel.B != 255 || CurrentPixel.A > 0){
           CurrentPixel.A = (byte)x;

I'm trying to write something to make the picture go slowly transparent, and i'm kinda of new to PDN Plugins :( So, could someone help me fix this? A picture is below:

You mean like fading? You can't, PDN only allows you to have 1 image which only changes once.

History repeats itself, because nobody was paying attention the first time.

OP isn't asking for animation, he's asking for a transparent gradient. I think. Maybe. Very ambiguous, really.

What do you mean, VoidWhisperer?

Oh, you're right. I think he means a transparency gradient, by the look of his images.

void Render(Surface dst, Surface src, Rectangle rect)
{
   double increment = 255.0 / (double) src.Width;

   for (int x = rect.Left; x < rect.Right; x++)
   {
       byte alpha = (byte) Math.Round(x * increment);

       for (int y = rect.Top; y < rect.Bottom; y++)
       {
           ColorBgra  CurrentPixel = src[x,y];
           CurrentPixel.A = alpha;
           dst[x,y] = CurrentPixel;
       }
   }
}

Edit: in codelab, rather than in pseudocode.
