imagecreatetruecolor(3) [php man page]


imagecreatetruecolor - Create a new true color image

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. NOTES
Note This function requires GD 2.0.1 or later (2.0.28 or later is recommended). SEE ALSO
