This code is supposed to draw arcs, but I keep getting that line at the bottom. Can anyone tell me what that is and how to get rid of it?

Here's the buggy code:

 1)
    {
        $iwborder = $arcwidth - $border;
        $ihborder = $archeight - $border;
        
        // The border
        imagefilledarc($crv, $arcdata[0], $arcdata[1], $arcwidth, $archeight,
                       $arcdata[2], $arcdata[3], $arc_color, IMG_ARC_PIE);
        
        // The filled arc
        imagefilledarc($crv, $arcdata[0], $arcdata[1], $iwborder, $ihborder,
                       $arcdata[2], $arcdata[3], $foreground_color, IMG_ARC_PIE);        
    }
    
    // The 'border' arc if the width is just 1
    else
    {
        // The filled arc
        imagefilledarc($crv, $arcdata[0], $arcdata[1], $arcwidth, $archeight,
                       $arcdata[2], $arcdata[3], $foreground_color, IMG_ARC_PIE);
        
        // The border    
        imagearc($crv, $arcdata[0], $arcdata[1], $arcwidth, $archeight,
                 $arcdata[2], $arcdata[3], $arc_color);
    }
}

// Displays the image based $imagetype
switch ($imagetype)
{
    // Displays the image as a JPEG
    case 1:
        header("Content-type: image/jpeg"); 
        imagejpeg($crv);
        break;
    
    // Displays the image as a PNG
    case 2:
        header("Content-type: image/png"); 
        imagepng($crv);
        break;
    
    // Displays the image as a GIF
    case 3:
        header("Content-type: image/gif"); 
        imagegif($crv);
        break;  
}

// Destroys the image
imagedestroy($crv);

// Ends the program
exit;


// ---------- Functions ----------

// Given $corner, $bwidth, and $bheight this returns an array with values
// to draw an arc
function create_arc($corner, $w, $h)
{
    $arc_ret = array();
    
    switch ($corner)
    {
        // top, left
        case "tl":
            $arc_ret = array($w, $h, 180, 270);
            break;
        
        // top, right
        case "tr":
            $arc_ret = array(0, $h, 270, 360);
            break;
        
        // bottom, left
        case "bl":
            $arc_ret = array($w, 0, 90, 180);
            break;
        
        // bottom, right
        case "br":
            $arc_ret = array(0, 0, 0, 90);
            break;
    }
    
    return($arc_ret);
}

// Error out
function error_out($message)
{
    if (@$message != "")
    {
        echo($message);
        exit;
    }
    else
    {
        error_out("Your error message needs a message.");
    }
}
