I'm trying to create my first plugin. The bit that I'm working on now is supposed to read the post title and create an image with that text in it. But for some reason it's not saving the image. Here's what I have:
// Get the post title from the post
$post_data = get_post($post->ID, ARRAY_A);
$post_slug = $post_data['post_name'];
$post_title = get_the_title( $post_id );
// Generate the image
$new_img = imagecreatetruecolor( 200, 80 );
$background = imagecolorallocate( $new_img, 200, 200, 200 );
$text_color = imagecolorallocate( $new_img, 150, 100, 100 );
$line_color = imagecolorallocate( $new_img, 128, 255, 0 );
imagestring( $new_img, 4, 30, 25, "$post_title", $text_color );
imagesetthickness ( $new_featured_img, 5 );
imageline( $new_featured_img, 30, 45, 165, 45, $line_color );
// Save the image
$upload_dir = wp_upload_dir();
$upload_dir_path = $upload_dir['baseurl'];
imagejpeg( $new_featured_img, "$upload_dir_path/$post_slug.jpg" );
imagecolordeallocate( $new_featured_img, $line_color );
imagecolordeallocate( $new_featured_img, $text_color );
imagecolordeallocate( $new_featured_img, $background );
}Here are the warnings it gives me:

Would greatly appreciate any guidance. Thanks.
