The basic four steps to generate an image using PHP are as follows:
- Creating a canvas image on which to work.
- Drawing Shapes or printing text on that canvas.
- Outputting the final graphic
- Cleaning up resources.
Sample PHP script: // Creating a canvas image $height = 200; $width = 200; $im = imagecreate($width, $height); $white = imagecolorallocate($im, 255, 255, 255); $black = imagecolorallocate($im, 0, 0, 0); // Drawing Shapes or printing text imagefill($im, 0, 0, $black); imageline($im, 0, 0, $width, $height, $white); imagestring($im, 4, 50, 150, 'Label text', $white); // Output image header('Content-type: image/png'); imagepng($im); // Clean up imagedestroy($im); ?>
