imagecreatetruecolor

(PHP 4 >= 4.0.6, PHP 5)

imagecreatetruecolor -- Create a new true color image

Description

resource imagecreatetruecolor ( int x_size, int y_size )

imagecreatetruecolor() returns an image identifier representing a black image of size x_size by y_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 differnet in issueing a warning instead of an error. Other versions only define this function, if the correct GD version is installed.

Пример 1. Creating a new GD image stream and outputting an image.

<?php
header ("Content-type: image/png");
$im = @imagecreatetruecolor(50, 100)
      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);
?>

Замечание: Эта функция нуждается в GD версии 2.0.1 или выше.

Замечание: This function will not work with GIF file formats.
