Claims
- 1. A data file for storing a still image, the data file comprising:
a plurality of decomposition levels representing the still image at increasingly higher levels of resolution, the decomposition levels being arranged in order of increasing levels of resolution; individual decomposition levels each comprising a plurality of subimages which allow reconstruction of an image representation of the still image, said subimages having rows of subimage values corresponding to rows of said image representation; said rows of subimage values being arranged within each particular decomposition level in row blocks, each row block containing a row of subimage values from a plurality of subimages of the particular decomposition level, wherein the rows of each row block correspond to a common image representation row.
- 2. A data file as recited in claim 1 wherein the subimages are transformed with a discrete wavelet transform.
- 3. A data file as recited in claim 1 wherein the row blocks are encoded.
- 4. A data file as recited in claim 1 wherein the row blocks are runlength encoded.
- 5. A data file as recited in claim 1 wherein each decomposition level comprises a separate set of subimages for each luminance and chrominance plane of the still image.
