ABSTRACT:
Methods and apparatus are provided for creating one or more compressed image tiles based on a compressed file that describes a digital image. In particular, the compressed image tiles are created without fully decompressing the compressed file. Each compressed image tile includes data corresponding to a portion of the digital image, and is independent of other compressed image tiles (i.e., may be decompressed without decompressing any other tile). In response to requests to display a desired portion of the digital image at a specific resolution, the compressed image tiles corresponding to the desired portion and the specified resolution are communicated via a band limited communication channel. In this regard, the portions of the digital image may be quickly communicated and displayed, without having to wait for the entire compressed file to be communicated over the band limited channel.
