i feel dumb asking this, bear me. know formula pixel position in linear array: pos = (y * width + x) * 4 which works fine. jsfiddle . before image/table linearized, same formula doesn't work. need use (let's discard rgba simplicity) pos = (y-1) * width + x why that? i'm missing simple. update: knew simple. silly me. in javascript pixel coordinates start @ 0, same coordinate system. pixel referenced top left corner, first pixel @ (0,0) , next going right (1,0) (2,0) , on. pixel below @ (0,1) give coordinates relative origin (0,0). we give sizes counts. when using width , height pixel counts , start @ 1 when count. 100th pixel on row 99. same 21th century in year 2015. so no need subtract 1 pixel coordinates.

i assume function overloading since has diff type of parameter .my question is two functions, has diff type of parameter, diff return type considered function overloading? public class header { public int addtwonumbers(int a, int b){ return a+b; } public double addtwonumbers(double a, double b){ return a+b; } independently of programming language, method overload occurs when 2 or more methods have same identifier while parameters different either in number, order , type. for example: // overloading public void x(int a, double b) { } public void x(double a, int b) { } in case, addtwonumbers overloaded because 2 methods share same identifier while parameters have different types.
