Assuming you have an image composed of lines drawn in different directions NE NS SE e.t.c, and with different colors(yellow, blue, black)? Can someone tell me what would be the fastest way to write a java code to be able to get the paths(x,y co-ordintes used to draws the lines) for lines of a particular color. without having to loop through all the pixels of the image.

  • are they Strait lines? – Madhawa Priyashantha Oct 14 '14 at 12:47
  • [drawLine()](http://docs.oracle.com/javase/7/docs/api/java/awt/Graphics.html#drawLine(int,%20int,%20int,%20int)) ? Or do you want to extract the lines? – Dawnkeeper Oct 14 '14 at 12:48
  • They are all straight lines, and i want the code to be able to say : from the following image extract all the lines or in order words for each line give me their paths(x,y coordinated used to draw each line so that a particular line would have an array of x,y coordinates) – user3099791 Oct 14 '14 at 12:55
  • I don't think it's possible... Perhaps you can grab some ms by forget some well choosen pixels – Emrys Myrooin Oct 14 '14 at 12:56
