Hello all,
I have a function which takes in a font (ttf or otf file) and generates an image of text in different fonts.
The problem I have is trying to work out how I can make the text fit in the image regardless of the font-size, type of font, and amount of text.
I have tried to make the image rectangle variable so that it contains the text of different fonts without cutting a bit of the text since the image is not long or wide enough.
Here is the function that I currently have, I have tried using the number of characters to determine the width of the image, but in some cases for some fonts and sizes, it still gets cut off.
function generate_image($save_path, $text, $font_path){
$length = strlen($text) * 15;
// Create the image
$im = imagecreatetruecolor($length, 40);
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 0, 0, $length, 40, $white);
$font = $font_path;
imagettftext($im, 30, 0, 0, 25, $black, $font, $text);
if(imagepng($im, $save_path)){
$status = true;
}else{
$status = false;
}
imagedestroy($im);
return $status;
}
Thank you all for any help
