Hi,
My App need to access the a file preview (image thumbnail or mimetype icons). From filecache table I can obtain the mimetype, and thus get the icon. The problem is how to get the image thumbnail.
PreviewManager
class has a getPreview
method, which expects a File $file
as argument.
I’m stuck right here: how can I load a File object from file id (or path) ?

\OC::$server->getRootFolder()->getById()
should do the trick
Hi Nick,
Thanks a lot for the tip!
In the meanwhile, I found out a simpler way of getting the preview, using
$preview_path = $rootURL . "index.php/core/preview.png?file=%2F" . $file_path . "&x=64&y=64";
The drawback of this method is that it looks like the preview is generated on the fly, so it takes a while for loading.
Regarding your suggestion,
\OC::$server->getRootFolder()->getById( $fileId )
returns me an array of OC\\Files\\Node\\File $file
.
If I make
$this->previewManager->getPreview($file)
I get back an OC\\Files\\SimpleFS\\SimpleFile
object. With this object, I would have to create a preview file, which turns out beeing the same as I described above. Is this right?
Is this the right way of getting an image file preview?
best,
alan
