// $text 字符串内容
// text_size 字符串大小
// text_angle 字型串输出角度
// text_x 字符串输出 x 坐标
// text_y 字符串输出 y 坐标

// **************************************** //
function img_text($img, $new_img, $text, $text_size, $text_angle, $text_x, $text_y, $text_font, $r, $g, $b){

$text=iconv("gb2312","UTF-8",$text);

$im = @imagecreatefromstring(file_get_contents($img)) or die ("打开图片失败!");
$color = ImageColorAllocate($im, $r,$g,$b);

//ImageTTFText(int im, int size, int angle, int x, int y, int col, string fontfile, string text):
//本函数将 TTF (TrueType Fonts) 字型文字写入图片。
//参数: size 为字形的尺寸;
// angle 为字型的角度,顺时针计算,0 度为水平(由左到右),90 度则为由下到上的文字;
// x,y 二参数为文字的坐标值 (原点为左上角);
// col 为字的颜色;
// fontfile 为字型文件名称;
// text 是字符串内容。
