How to get file object from file path in Concrete5?

Question

I want to get thumbnail from the file inside the themes directory but getThumbnail() function requires me to pass a file object.

This obviously doesn't work:

$v = View::getInstance();
$themePath = $v->getThemePath();    
$thumbnail = $imageHelper->getThumbnail($themePath.'/images/abc.jpg', 100, 100, true);

So is it possible to get file object from the file path?

Answer 1

If the file exists only in the folder structure but not as concrete5 File Object, you need the FileImporter first:

use Concrete\Core\File\Importer;
$fi = new Importer();
if($fv = $fi->importIncomingFile($themePath . '/' . $filename)){
    $returnFile = \Concrete\Core\File\File::getByID($fv->getFileID());
}

Then you may pass that file object to the getThumbNail() function. The getThumbNail() doesn't take a path but an image object as first parameter:

$imageHelper = Core::make('helper/image');    
$thumbnail = $imageHelper->getThumbnail($returnFile, 300, 9999, false);

Here are all params that are taken (from the API):

/**
 * Returns a path to the specified item, resized and/or cropped to meet max width and height. $obj can either be
 * a string (path) or a file object.
 * Returns an object with the following properties: src, width, height
 * @param mixed $obj
 * @param int $maxWidth
 * @param int $maxHeight
 * @param bool $crop
 */
public function getThumbnail($obj, $maxWidth, $maxHeight, $crop = false)
