function immagine

[Rossella_75]

ok risolto, semplicemente cosi

    function SaveProportionateImage($filename, $quality, $width){ 

        $dest_width = $width; 

        $ratio = $this->src_width / $dest_width; 

        $dest_image = imagecreatetruecolor( $this->src_height / $ratio,$dest_width); 

        imagecopyresampled($dest_image, $this->src_image, 0, 0, 0, 0, 

            $this->src_height / $ratio, 

            $this->src_width / $ratio, 

            $this->src_height, 

            $this->src_width); 

        imagejpeg($dest_image, $filename.'.jpg', $quality); 

        imagedestroy($dest_image); 

    }
