Abstract: Improved transforms are used to encode and decode large video and image blocks. During encoding, a prediction residual block having a large size (e.g., larger than 32×32) is generated. The pixel values of the prediction residual block are transformed to produce transform coefficients. After determining that the transform coefficients exceed a threshold cardinality representative of a maximum transform block size (e.g., 32×32), a number of the transform coefficients are discarded such that a remaining number of transform coefficients does not exceed the threshold cardinality. A transform block is then generated using the remaining number. During decoding, after determining that the transform coefficients exceed the threshold cardinality, a number of new coefficients are added to the transform coefficients such that a total number of transform coefficients exceeds the threshold cardinality. The transform coefficients are then inverse transformed into a prediction residual block having a large size.

A print-ready compressed file may be generated by raster image processing of a job description file associated with a rendering job provided by a digital front end. The expansion time with respect to one or more expansion processes may be predicted by a linear equation during assembly of the compressed file. The linear equation may be formulated based on measured compression statistics that relate to profile data within the compressed file.

The expansion time to perform the print-time imaging operations may be compared with an available time based on an image output terminal speed to improve performance of raster image processing.
