                                imagefilledarc

   (PHP 4 >= 4.0.6)
   imagefilledarc -- Draw a partial ellipse and fill it

Description

   bool imagefilledarc ( resource image, int cx, int cy, int w, int h,
   int s, int e, int color, int style)

   imagefilledarc() draws a partial ellipse centered at cx, cy (top left
   is 0, 0) in the image represented by image. Returns TRUE on success or
   FALSE on failure. 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. style is a bitwise OR of the
   following possibilities:

    1. IMG_ARC_PIE
    2. IMG_ARC_CHORD
    3. IMG_ARC_NOFILL
    4. IMG_ARC_EDGED

   IMG_ARC_PIE and IMG_ARC_CHORD are mutually exclusive; IMG_ARC_CHORD
   just connects the starting and ending angles with a straight line,
   while IMG_ARC_PIE produces a rounded edge. IMG_ARC_NOFILL indicates
   that the arc or chord should be outlined, not filled. IMG_ARC_EDGED,
   used together with IMG_ARC_NOFILL, indicates that the beginning and
   ending angles should be connected to the center - this is a good way
   to outline (rather than fill) a 'pie slice'.

   Example 1. Creating a 3D looking pie
   <?php
   // this example is provided by poxy at klam dot is
   // create image
   $image = imagecreate(100, 100);
   // allocate some solors
   $white    = imagecolorallocate($image, 0xFF, 0xFF, 0xFF);
   $gray     = imagecolorallocate($image, 0xC0, 0xC0, 0xC0);
   $darkgray = imagecolorallocate($image, 0x90, 0x90, 0x90);
   $navy     = imagecolorallocate($image, 0x00, 0x00, 0x80);
   $darknavy = imagecolorallocate($image, 0x00, 0x00, 0x50);
   $red      = imagecolorallocate($image, 0xFF, 0x00, 0x00);
   $darkred  = imagecolorallocate($image, 0x90, 0x00, 0x00);
   // make the 3D effect
   for ($i = 60; $i > 50; $i--) {
      imagefilledarc($image, 50, $i, 100, 50, 0, 45, $darknavy,
   IMG_ARC_PIE);
     imagefilledarc($image, 50, $i, 100, 50, 45, 75 , $darkgray,
   IMG_ARC_PIE);
     imagefilledarc($image, 50, $i, 100, 50, 75, 360 , $darkred,
   IMG_ARC_PIE);
   }
   imagefilledarc($image, 50, 50, 100, 50, 0, 45, $navy, IMG_ARC_PIE);
   imagefilledarc($image, 50, 50, 100, 50, 45, 75 , $gray, IMG_ARC_PIE);
   imagefilledarc($image, 50, 50, 100, 50, 75, 360 , $red, IMG_ARC_PIE);
   // flush image
   header('Content-type: image/png');
   imagepng($image);
   imagedestroy($image);
   ?>

     Note: This function was added in PHP 4.0.6 and requires GD 2.0.1
