imagefilledellipse() Drawing of ellipse by filling with colours using gd support in PHP

<?Php
header ("Content-type: image/jpeg");
$width=301;$height=250;
$im = @ImageCreate ($width, $height) 
 or die ("Cannot Initialize new GD image stream");
ImageColorAllocate($im,255,255,255);

$text_color=ImageColorAllocate($im,255,0,0);  // border colour  
$fill_color=ImageColorAllocate($im,0,128,255); // fill colour 
imagefilledellipse($im,150,125,250,140,$fill_color); // draw ellipse and fill colour

Imagejpeg ($im); // show the filled ellipse 
imagedestroy($im); //memory is cleared.
?>

filled ellipse using imagefilledellipse()

Syntax

imagefilledellipse($image,$center_x,$center_y,$width,$height,$color)

Returns true or false based on success of failure.

`$image`	Image created using ImageCreate() or imagecreatetruecolor()
`$center_x`	x coordinate of center ( X : Horizontal )
`$center_y`	y coordinate of center ( Y : Vertical )
`$width`	Width of the ellipse
`$height`	Height of the ellipse
`$color`	Color to fill the ellipse by using imagecolorallocate().

Creating full circle using imagefilledellipse()

We need to maintain $width and $height equal .
By using imageellipse() we created one face, to this image now we will be adding eye balls by using imagefilledellipse().

Example

Face with eye balls using imagefilledellipse

<?Php
header ("Content-type: image/jpeg");
$width=301;$height=301;
$im = @ImageCreate ($width, $height) 
 or die ("Cannot Initialize new GD image stream");
ImageColorAllocate($im,255,255,255);
$text_color=ImageColorAllocate($im,255,0,0);   
imageellipse($im,150,150,290,290,$text_color); // outer face
imageellipse($im,80,100,50,50,$text_color); // left eye 
imageellipse($im,220,100,50,50,$text_color); // right eye
imageellipse($im,150,200,70,10,$text_color); // mouth

$fill_color=ImageColorAllocate($im,0,128,255); // eye ball colour
imagefilledellipse($im,80,100,20,20,$fill_color); // left eye ball
imagefilledellipse($im,220,100,20,20,$fill_color); // right eye ball
 Imagejpeg ($im);
 imagedestroy($im); //memory is cleared.
?>

By changing the position of eye ball we can create different type of face ( emoji )

$move_left=0;
$move_top=-15;

$move_left=-15;
$move_top=0;

$move_left=-15; // x position is moved right 
$move_top=0; // Y position not changed  
$fill_color=ImageColorAllocate($im,0,245,255);
imagefilledellipse($im,80-$move_left,100-$move_top,20,20,$fill_color); 
imagefilledellipse($im,220-$move_left,100-$move_top,20,20,$fill_color);

Try to create different movement of eye balls and mouth ellipse representing different face expressions ( emoji )

Concentric circle using imagefilledellipse()

Random numbers are gnerated between 1 and 255 for adding differnt colors. Common center for all the circles.

    $r=rand(1,255);
    $g=rand(1,255);
    $b=rand(1,255);	
    $fill_color = ImageColorAllocate ($im, $r, $g,$b);    
imagefilledellipse($im,$width/2,$height/2,$width-$i,$height-$i,$fill_color);
}
Imagejpeg ($im);
imagedestroy($im); //memory is cleared.
?>
