Be careful though that this method is not asynchronous and thus may take some time to process if thumbnail creation processing is long.

Parameters:

fileDoc - a FileDocument of which to create thumbnail

srcFile - a File of which to create thumbnail

url - an URL of which to create thumbnail

format - the ImageFormat of the file to generate (default to JPEG if null)

maxWidth - the maximum width of the thumbnail to generate

maxHeight - the maximum height of the thumbnail to generate
