ANA.GetPixelColor_5V
Get the Color of 5 successive vertical Pixels from an Image-Register (IR)
Intention
This command will read the color of 5 successive vertical Pixels in an IR. Its an Option to Speed up Image-Processing.
With this command, the returned value is the 24-bit color of the Pixels.
You do not need to worry, if the resolution is not a multiple of 5, illegal Coordinates will just be ignored.
Due to the use of a nested Loop going "Line by Line" through all Pixels, it is recommended to start the script in the Editor using "Freerun Mode".
Free-Run Button
You will not see the Robot Painting unless the Show command is been called which leads to an Update in the Show-Window.

P5 - Variable for returned Color-Value of Pixel 2 at (X1,Y1+1)
P6 - Variable for returned Color-Value of Pixel 3 at (X1,Y1+2)
P7 - Variable for returned Color-Value of Pixel 4 at (X1,Y1+3)
P8 - Variable for returned Color-Value of Pixel 5 at (X1,Y1+4)
Example
See above.
Remarks
The ANA.GetPixelColor_5V is optimized for Speed. It will use only about 580 Ticks. Therefore the Robot could read more then 27500*5 Pixels per Second.
