# imagecreatetruecolor

(PHP 4 >= 4.0.6, PHP 5)

imagecreatetruecolor — Create a new true color image

### 설명

resource imagecreatetruecolor ( int `$width` , int `$height` )

imagecreatetruecolor() 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 different in issuing a warning instead of an error. Other versions only define this function, if the correct GD version is installed.

### 인수

`width`

  Image width.

`height`

  Image height.

### 반환값

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

### 예제

or die('Cannot Initialize new GD image stream');

imagestring($im, 1, 5, 5, 'A Simple Text String', $text_color);
imagepng($im);
imagedestroy($im);
?>`
