# imagearc

(PHP 3, PHP 4 , PHP 5)

imagearc -- Draw a partial ellipse

## Description

int imagearc ( resource image, int cx, int cy, int w, int h, int s, int e, int color)

imagearc() draws a partial ellipse centered at `cx`, `cy` (top left is 0, 0) in the image represented by `image`. `W` and `h` specifies the ellipse's width and height respectively while the start and end points are specified in degrees indicated by the `s` and `e` arguments. 0° is located at the three-o'clock position, and the arc is drawn counter-clockwise.

예 1. Drawing a circle with imagearc()
