Abstract
A method of processing a viewport within an image arranged as a matrix of tiles from a container file is provided. The method includes reading data of the viewport starting from a point of origin of the viewport, the viewport having a pixel width and a pixel height, the viewport being a portion of an image stored in a record within the file container; reading record metadata of the record; computing column numbers or row numbers, or both, of the tiles containing the viewport; and launching parallel or asynchronous read requests for each row or each column of the viewport.
