Using PHP GD to create image form text with different fonts.
- by Meredith
I have been using this simple script to generate images from text:
<?php
header('Content-type: image/png');
$color = RgbfromHex($_GET['color']);
$text = urldecode($_GET['text']);
$font = 'arial.ttf';
$im = imagecreatetruecolor(400, 30);
$bg_color = imagecolorallocate($im, 255, 255, 255);
$font_color = imagecolorallocate($im, $color[0], $color[1], $color[2]);
imagefilledrectangle($im, 0, 0, 399, 29, $bg_color);
imagettftext($im, 20, 0, 10, 20, $font_color, $font, $text);
imagepng($im);
imagedestroy($im);
function RgbfromHex($hexValue) {
if(strlen(trim($hexValue))==6) {
return array(
hexdec(substr($hexValue,0,2)), // R
hexdec(substr($hexValue,2,4)), // G
hexdec(substr($hexValue,4,6)) // B
);
}
else return array(0, 0, 0);
}
?>
I call the script with file.php?text=testing script&color=000000
Now I'd like to know how could I generate text with normal and bold fonts mixed in the same image, something like file.php?text=testing <b>script</b>&color=000000
