imagecreatetruecolor - Create a new true color image

SYNOPSIS

       resource imagecreatetruecolor (int  $width, int	$height)

DESCRIPTION

       imagecreatetruecolor(3) returns an image identifier representing a black image of the specified size.

	Depending  on your PHP and GD versions this function is defined or not. With PHP 4.0.6 through 4.1.x this function always exists if the GD
       module is loaded, but calling it without GD2 being installed PHP will issue a fatal error and exit. With PHP 4.2.x this behaviour  is  dif-
       ferent in issuing a warning instead of an error. Other versions only define this function, if the correct GD version is installed.

PARAMETERS

	      o $width
		- Image width.

	      o $height
		- Image height.

RETURN VALUES

       Returns an image resource identifier on success, FALSE on errors.

EXAMPLES

       Example #1

	       Creating a new GD image stream and outputting an image.

	      <?php
	      header ('Content-Type: image/png');
	      $im = @imagecreatetruecolor(120, 20)
		    or die('Cannot Initialize new GD image stream');
	      $text_color = imagecolorallocate($im, 233, 14, 91);
	      imagestring($im, 1, 5, 5,  'A Simple Text String', $text_color);
	      imagepng($im);
	      imagedestroy($im);
	      ?>

	      The  above  example  will  output something similar to:[NOT DISPLAYABLE MEDIA]Output of example : Creating a new GD image stream and
	      outputting an image.

       Note

	      This function requires GD 2.0.1 or later (2.0.28 or later is recommended).
