How-to swap channels ?

[MarsWalker]

Hi,

I'm trying to do some IR photography and found a excellent site for it.

The problem is that one of the things to do is to swap the red and the blue channels.

Can anyone help me ?

Thanks in advance,

Look for a plugin called Curves+ by pyrochild. That can do it.

Yes, but Ed Harvey's Color Flip / Rotate can do it easier.

Yeah, and so would this CodeLab script:

void Render(Surface dst, Surface src, Rectangle rect)
{
   ColorBgra CurrentPixel;
   for (int y = rect.Top; y     {
       for (int x = rect.Left; x         {
           CurrentPixel = src[x,y];
           byte tempR = CurrentPixel.R;
           CurrentPixel.R = CurrentPixel.B;
           CurrentPixel.B = tempR;
           dst[x,y] = CurrentPixel;
       }
   }
}

Yeah, and so would this CodeLab script:

void Render(Surface dst, Surface src, Rectangle rect)
{
   ColorBgra CurrentPixel;
   for (int y = rect.Top; y < rect.Bottom; y++)
   {
       for (int x = rect.Left; x < rect.Right; x++)
       {
           CurrentPixel = src[x,y];
           byte tempR = CurrentPixel.R;
           CurrentPixel.R = CurrentPixel.B;
           CurrentPixel.B = tempR;
           dst[x,y] = CurrentPixel;
       }
   }
}

Hey, that's kinda like a bubble sort!

Pretty convenient that I am Mayor of Bizzaro world, hmm? ;-)

I am the Emperor of Bizzaro world, how convenient

That just means that I am more in-touch with the locals...
