title: "Get Pixel" loop misses pixels it should have found. (In Small Basic)
body: <p>Here's the code in Small Basic:</p>
  
  <pre><code>GraphicsWindow.CanResize = 0
  GraphicsWindow.Width = 201
  GraphicsWindow.Height = 300
  X = 0
  circumstance = 0
  
  'Initialization
  GraphicsWindow.SetPixel(100,0,"Black")
  code = "01111111"
  
  
  'Start
  For i=1 To GraphicsWindow.Height
  For X=0 To GraphicsWindow.Width
  Program.Delay(1)
  
  If X&gt;0 Then
    If GraphicsWindow.GetPixel(X-1,i-1) = "Black" Then
      circumstance = circumstance + 1
    EndIf
  EndIf  
  
  If GraphicsWindow.GetPixel(X,i-1) = "Black" Then
    circumstance = circumstance + 10
  EndIf
  
  If X&lt;GraphicsWindow.Width Then
    If GraphicsWindow.GetPixel(X+1,i-1) = "Black" Then
      circumstance = circumstance + 100
    EndIf
  EndIf  
  
  TextWindow.WriteLine(circumstance)
    EndFor
  EndFor
  </code></pre>
  
  <p>What it does is it looks through the Graphics Window pixel by pixel.
  The variable "circumstance" is what it found.
  If there is a black pixel to the top left of the target pixel, the first digit will be 1.
  If there is a black pixel to the top of the target pixel, the second digit will be 1.
  If there is a black pixel to the top right of the target pixel, the third digit will be 1.
  But no matter what I try circumstance always outputs 000. </p>
