Re: How to use Wx::GetPixel function

Hi:

From the wxWidgets docs, the wxColour object has methods:

   GetAsString(wxC2S_NAME | wxC2S_CSS_SYNTAX) - returns a text
representation
   GetRGB()
- returns 32bit value
   GetRGBA()                                                              -
returns 32bit value

The above constants weren't easy to find for me. I think I used 2 for what
I needed.

One of these should help.
