PHP upscale an image? -


i new php , trying learn image upscaling. can please show me how can upscale image size? example, re-size following image while keeping aspect ratio. if can done, can please show me example enter image description here

$source_image = imagecreatefromjpeg("osaka.jpg"); $source_imagex = imagesx($source_image); $source_imagey = imagesy($source_image); $dest_imagex = 300; $dest_imagey = 200; $dest_image = imagecreatetruecolor($dest_imagex, $dest_imagey);

poor quality, fast:

imagecopyresized($dest_image, $source_image, 0, 0, 0, 0,              $dest_imagex, $dest_imagey, $source_imagex, $source_imagey);

best quality, slow:

imagecopyresampled($dest_image, $source_image, 0, 0, 0, 0,              $dest_imagex, $dest_imagey, $source_imagex, $source_imagey);
