(PHP 3, PHP 4, PHP 5)imagearc -- Draw a partial ellipse

Description

bool 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 clockwise.
