The GmagickDraw::ellipse() function is an inbuilt function in PHP which is used to draw an ellipse on the image.
Syntax:
GmagickDraw GmagickDraw::ellipse( float $ox, float $oy, float $rx, float $ry, float $start, float $end )
Parameters: This function accepts six parameters as mentioned above and described below:
- $ox: It specifies the x-coordinate of the ellipse.
- $oy: It specifies the y-coordinate of the ellipse.
- $rx: It specifies the x-radius of the ellipse.
- $ry: It specifies the y-radius of the ellipse.
- $start: It specifies the start point of the ellipse.
- $end: It specifies the end point of the ellipse.
Return Value: This function returns an GmagickDraw object on success.
Exceptions: This function throws GmagickDrawException on error.
Below given programs illustrate the GmagickDraw::ellipse() function in PHP:
Program 1 (Simple ellipse):
<?php // Create a new Gmagick object $gmagick = new Gmagick( 'geeksforgeeks.png' );
// Create a GmagickDraw object $draw = new GmagickDraw();
// Set the color $draw ->setFillColor( '#0E0E0E' );
// Function to draw rectangle $draw ->rectangle(-10, -10, 800, 400);
// Set the fill color $draw ->setFillColor( '#3D99D4' );
// Set the stroke width $draw ->setStrokeWidth(5);
// Draw a ellipse $draw ->ellipse(125, 70, 100, 50, 0, 360);
// Use of drawimage function $gmagick ->drawImage( $draw );
// Display the output image header( "Content-Type: image/png" );
echo $gmagick ->getImageBlob();
?> |
Output:
Program 2 (Stroked ellipse):
<?php // Create a new Gmagick object $gmagick = new Gmagick( 'geeksforgeeks.png' );
// Create a GmagickDraw object $draw = new GmagickDraw();
// Set the color $draw ->setFillColor( '#0E0E0E' );
// Function to draw rectangle $draw ->rectangle(-10, -10, 800, 400);
// Set the fill color $draw ->setFillColor( 'blue' );
// Set the stroke color $draw ->setstrokecolor( 'green' );
// Set the stroke width $draw ->setStrokeWidth(5);
// Draw a ellipse $draw ->ellipse(225, 70, 150, 50, 0, 360);
// Use of drawimage function $gmagick ->drawImage( $draw );
// Display the output image header( "Content-Type: image/png" );
echo $gmagick ->getImageBlob();
?> |
