示例1: text_image
/**
* Create a GD image with text.
*
* @param string $text The text to use. TTF fonts accept HTML character codes.
* @param integer $size Fontsize in pixels. For non-truetype fonts, size has a range of [1-5] points.
* @param integer $padding Padding in pixels arround the text
* @param string $color Color of the text
* @param string $background Background for the text. Default is transparent background.
* @param integer $radius Radius of rounded corners ont eh background if desired
* @return resource GD resource with text.
