go though each row of array put the value of color in to memory then read next value in the row while it has the same color when you find different color value or reach the end of row
draw the line of the color from start point to end point, and continue the process.

Ghost: I assume you are searching for a simple point/triangle collision test?

Ghost: I think I figured out what you want now. In that case I think you should just take the angle of the "radar scan" line and the angle of the particle and the center and if its small enough just blink :)

dear ghost,
if you can find some demo/picture where's similar effect, could you please show it?

You could try this:

Your particle (or spot) has a number assigned to it, that represents its current brightness (color), and as time passes by, you decrease the number. Whenever the radar-line hits the spot, the number is increased to the max. I mean something like:

color = color * exp(lastTime - currentTime);
if (radar hit pixel) color = 255;

where "radar hit pixel" is done the way gargaj explained. Hope this helps.
