EXAMPLES

       Example #1

	      A newt_draw_root_text(3) example

	       This code demonstrates drawing of titles in the both corners of the screen.

	      <?php
	       newt_init();
	       newt_cls();

	       newt_draw_root_text (2, 0, "Some root text");
	       newt_refresh();
	       sleep(1);

	       newt_draw_root_text (-30, 0, "Root text in the other corner");

imagettfbbox - Give the bounding box of a text using TrueType fonts

SYNOPSIS

       array imagettfbbox (float  $size, float	$angle, string	$fontfile, string  $text)

DESCRIPTION

	This function calculates and returns the bounding box in pixels for a TrueType text.

PARAMETERS

	      o $size
		- The font size.

	      Note

		      In GD 1, this is measured in pixels. In GD 2, this is measured in points.

	      o $angle
		- Angle in degrees in which $text will be measured.

	      o $fontfile
		-  The	name  of  the  TrueType  font  file (can be a URL). Depending on which version of the GD library that PHP is using, it may
		attempt to search for files that do not begin with a leading '/' by appending  '.ttf'  to  the	filename  and  searching  along  a
		library-defined font path.

	      o $text
		- The string to be measured.

RETURN VALUES

       imagettfbbox(3)	returns  an  array  with  8  elements representing four points making the bounding box of the text on success and FALSE on
       error.

       +----+--------------------------------+
	The points are relative to the text regardless of the $angle, so "upper left" means in the top left-hand corner seeing the  text  horizon-
       tally.

	      // First we create our bounding box for the first text
	      $bbox = imagettfbbox(10, 45, $font, 'Powered by PHP ' . phpversion());

	      imagettftext($im, 10, 45, $x, $y, $black, $font, 'Powered by PHP ' . phpversion());

	      // Create the next bounding box for the second text
	      $bbox = imagettfbbox(10, 45, $font, 'and Zend Engine ' . zend_version());

	      // Set the cordinates so its next to the first text
	      $x = $bbox[0] + (imagesx($im) / 2) - ($bbox[4] / 2) + 10;
	      $y = $bbox[1] + (imagesy($im) / 2) - ($bbox[5] / 2) - 5;

	      // Write it
	      imagettftext($im, 10, 45, $x, $y, $black, $font, 'and Zend Engine ' . zend_version());

	      // Output to browser
	      header('Content-Type: image/png');

	      imagepng($im);
	      imagedestroy($im);
	      ?>

NOTES

       Note

	       This function requires both the GD library and the FreeType library.
