<span style= "White-space:pre" ></span>//default Logoprivate function generation_default_img ($width, $height, $img _type, $output _url) {//check if the default logo exists if (file_exists ($output _url)) {return;} else{//Create a new true color image and return an image identifier header (' Content-type:image/png '); $im = Imagecreate ($width, $height);        <span style= "White-space:pre" ></span>//assign color        <span style= "White-space:pre" ></span> $BG _color = Imagecolorallocate ($im, 255, 255, 255); <span style= "White-space:pre" ></span>        //Draw a rectangle and fill < Span style= "White-space:pre" ></span>        imagefilledrectangle ($im, 0, 0, $width, $height, $BG _color);        <span style= "White-space:pre" ></span>imagepng ($im, $output _url); <span style= "White-space:pre" > </span>        Imagedestroy ($im);}}
