The present technique selectively handles image data, which is decomposed
into a plurality of resolution levels. In one embodiment, an image
resolution suitable for display in a desired viewport is selected via an
iterative process including determining whether scaling of one of the
different image resolutions of the plurality of different image
resolutions by a predetermined scaling threshold would result in a scaled
image resolution that is less than or equal to the resolution of the
desired viewport. A portion of the plurality of data sets may be
selectively requested for recomposition of the image at the image
resolution. Additional systems, methods, and devices for handling image
data are also disclosed.
