我在这一行收到上述错误：

imagefill($canvas, 0, 0, imagecolorallocate($canvas, 255, 255, 255));

该脚本适用于所有图像类型，但如果分辨率大于4000 x 3000像素，则会崩溃。图像本身只有500kb。这是所有代码：

$canvas = imagecreatetruecolor(imagesx($source), imagesy($source));
imagefill($canvas, 0, 0, imagecolorallocate($canvas, 255, 255, 255));
imagealphablending($canvas, TRUE);
imagecopy($canvas, $source, 0, 0, 0, 0, imagesx($source), imagesy($source));
imagedestroy($source);
$quality = 100; // 0 = worst / smaller file, 100 = better / bigger file 
imagejpeg($canvas, $strPath.$p_Id.".jpg", $quality);        //----- save image
ImageDestroy($canvas);
