我有以下函数生成并保存基于文本参数的图像。 我怎么能在我的文件中称此? 我试过了
INCLUDE 'outPrice.php';
链接到外部PHP以及与此命令调用它,
outPrice($text);
为了这我得到了以下回应。
Warning: Cannot modify header information - headers already sent
任何帮助,将不胜感激。
function outPrice($textval){
$textcolor = '666666';
$font="bgtbt.ttf";
$size = 20;
$padding= 1;
$bgcolor= "ffffff";
$transparent = 0;
$antialias = 0;
$fontfile = $fontpath.$font;
$box= imageftbbox( $size, 0, $fontfile, $textval, array());
$boxwidth= $box[4];
$boxheight= abs($box[3]) + abs($box[5]);
$width= $boxwidth + ($padding*2) + 1;
$height= $boxheight + ($padding) + 0;
$textx= $padding;
$texty= ($boxheight - abs($box[3])) + $padding;
// create the image
$png= imagecreate($width, $height);
$color = str_replace("#","",$bgcolor);
$red = hexdec(substr($bgcolor,0,2));
$green = hexdec(substr($bgcolor,2,2));
$blue = hexdec(substr($bgcolor,4,2));
$bg = imagecolorallocate($png, $red, $green, $blue);
$color = str_replace("#","",$textcolor);
$red = hexdec(substr($textcolor,0,2));
$green = hexdec(substr($textcolor,2,2));
$blue = hexdec(substr($textcolor,4,2));
$tx = imagecolorallocate($png, $red, $green, $blue);
imagettftext( $png, $size, 0, $textx, $texty, $tx, $fontfile, $textval );
header("content-type: image/jpeg");
imagejpeg($png, "price".$textval.".jpg");
imagedestroy($png);
}
