I have some code below that takes an existing png file, adds some dynamic copy to it and generates a new image with the copy included into the image. Works great, no issues.
Problem I'm finding is I need to include the image along with some typical html content when the page is called. I can't add any html etc. to it because of the header info. Without it, the page just displays as raw gibberish for the image.
How can I get the dynamic image to display along with some html content?
$name = $_REQUEST["name"];
$filename = "certificate.png"; //name of image file
$fontsize = 30; //size of font
$fontfile = "Arial"; //name of ttf file, w/o ttf extension (courier in this case)
$text = "Congratulations ".$name.""; //text to write centered
$text2 = "You will receive $1000"; //second line to write centered
$im = imagecreatefrompng ($filename); //create the image resource
list ($im_width, $im_height) = getimagesize($filename);
//calculate the size of the bounding box
$bbox = imagettfbbox($fontsize, 0, $fontfile, $text);
$bbox2 = imagettfbbox($fontsize, 0, $fontfile, $text2);
$text_width = $bbox-$bbox;
$text_height = $bbox-$bbox;
$text_width2 = $bbox2-$bbox2;
$text_height2 = $bbox2-$bbox2;
//write the text to the file, centered as calculated from (W-w)/2
//where W is the image dimension and w is the text dimension
imagettftext($im, 30, 0, ($im_width-$text_width)/2, ($im_height-$text_height)/2, 0, $fontfile, $text);
imagettftext($im, 20, 0, ($im_width-$text_width2)/2, ($im_height-$text_height2)/2 + 40, 0, $fontfile, $text2);
//destroy the image resource
