       special color IMG_COLOR_STYLED or lines of images with color IMG_COLOR_STYLEDBRUSHED.

PARAMETERS

	      o $
		image -An image resource, returned by one of the image creation functions, such as imagecreatetruecolor(3).

	      header("Content-type: image/jpeg");

	      $w   = imagecolorallocate($im, 255, 255, 255);
	      $red = imagecolorallocate($im, 255, 0, 0);

	      /* Draw a dashed line, 5 red pixels, 5 white pixels */
	      $style = array($red, $red, $red, $red, $red, $w, $w, $w, $w, $w);
	      imagesetstyle($im, $style);
	      imageline($im, 0, 0, 100, 100, IMG_COLOR_STYLED);

	      /* Draw a line of happy faces using imagesetbrush() with imagesetstyle */
	      $style = array($w, $w, $w, $w, $w, $w, $w, $w, $w, $w, $w, $w, $red);
	      imagesetstyle($im, $style);

	      $brush = imagecreatefrompng("http://www.libpng.org/pub/png/images/smile.happy.png");
	      $w2 = imagecolorallocate($brush, 255, 255, 255);
	      imagecolortransparent($brush, $w2);
	      imagesetbrush($im, $brush);
	      imageline($im, 100, 0, 0, 100, IMG_COLOR_STYLEDBRUSHED);

	      imagejpeg($im);

imagefilledarc - Draw a partial arc and fill it

SYNOPSIS

       bool imagefilledarc (resource  $image, int  $cx, int  $cy, int  $width, int  $height, int  $start, int  $end, int  $color, int  $style)

DESCRIPTION

	Draws a partial arc centered at the specified coordinate in the given $image.

PARAMETERS

	      o $
		image -An image resource, returned by one of the image creation functions, such as imagecreatetruecolor(3).

	      o $cx
		- x-coordinate of the center.

	      o $cy
		- y-coordinate of the center.

	      o $width
		- The arc width.

	      o $height
		- The arc height.

	      o $start
		- The arc start angle, in degrees.

	      o $end
		- The arc end angle, in degrees. 0o is located at the three-o'clock position, and the arc is drawn clockwise.

	      o $color
		- A color identifier created with imagecolorallocate(3).

	      o $style
		- A bitwise OR of the following possibilities:

		     o IMG_ARC_PIE

		     o IMG_ARC_CHORD

		     o IMG_ARC_NOFILL

		     o 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'.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      Creating a 3D looking pie

	      <?php

	      // create image
	      $image = imagecreatetruecolor(100, 100);

	      // allocate some colors
	      $white	= imagecolorallocate($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);
	      ?>
