$ Font_file = "c: \ WINDOWS \ Fonts \ simhei. ttf ";
// Generate a big snowflake, which is actually calling imagettftext () to output the * number
For ($ I = 1; $ I <= 400; $ I ++)

Header ("Content-Type: image/gif ");
$ Img = imagecreatetruecolor (50, 50 );

PHP drawing problems, urgent

1) Check whether your PHP does not support the GD Library. In windows,
Simply remove the semicolon before extension = php_gd2.dll in php. ini.
For linux systems, check the instructions on installing the GD library in the php Reference Manual.

2) sample code:

// Create an image of 520*300,
$ Im = imagecreatetruecolor (520,300 );
Imagefilledrectangle ($ im, 0, 0,520,300, 0 xFFFFFF );
Imageline ($ im, 10,270,510,270, 0x000000 );
......

// Save the image to file and free memory
Imagepng ($ im, 'photo_stamp.png ');
Imagedestroy ($ im );
?>
3) draw other systems in sequence.
