摘要： A plurality of patterns such as solid patterns, edge patterns, half-tone patterns, and verbatim data are losslessly represented in a compressed raster data stream. A pattern selection module selects among the various patterns to provide the best combination of lossless representations according to particular criteria such as storage compactness. A packet formatting module packs multiple pattern identifiers and lossless representations into a packet which may be transmitted compactly. Upon receipt, a packet deformatting module unpacks the pattern identifiers and lossless representations from the packet. After deformatting, a pattern decoding module uses the pattern identifier to activate appropriate pattern generation modules. Each pattern generation module regenerates data according to an indicated pattern to recreate the original raster data.

摘要： A method for compressing image data having pixels arranged like a matrix in a line direction and a sub scan direction orthogonal to the line direction is provided. The method includes the steps of dividing the image data in the line direction and in the sub scan direction into blocks covering a plurality of lines, determining a representative value about density of pixels included in each of the blocks, determining additional information for each one line in each of the blocks or for each plurality of lines whose number is smaller than the number of lines of the block in each of the blocks, the additional information being information about the density of each of the pixels to be used instead of the representative value or to be added to the representative value, if there is, and creating compressed data by using the representative value and the additional information.

摘要： Traps are produced at color boundaries in a print page that is present in the form of run-length encoded image data, by way of distance mapping. Distances of the run lengths to an adjacent color are determined without decoding the run lengths into a pixel matrix, and the traps are produced on the basis of the distances thus determined. For this purpose, distance vectors are determined for the starting point and for the end point of a run length. The distance vectors are in each case recalculated from the comparison with the distance vectors of adjacent run lengths. The new values of the distance vectors replace the previous values of the distance vectors if the magnitudes of the distances of the new values are less than the magnitudes of the distances of the previous values.

摘要： A printer driver software product is provided for execution by a computer to produce compressed page data corresponding to a page layout. The driver includes instructions to generate continuous-tone data and bi-level text and black graphics data from print data corresponding to the page layout. Data compression instructions are also included in the printer driver. Upon execution the data compression instructions cause the computer to compress the set of continuous-tone data and the set of bi-level text and black graphics data to produce compressed page data corresponding to the page layout. The compressed data is then transmitted to a printer in communication with the computer. A printer driver software product according to the invention is particularly useful where a printer is coupled to a computer by means of a relatively limited bandwidth connection.

摘要： A system and method facilitating progressively transforming and coding digital pictures is provided. The present invention via employment of a multi-resolution lapped transform provides for progressive rendering as well as mitigation of blocking artifacts and ringing artifacts as compared to many conventional compression systems. The invention includes a color space mapper, a multi-resolution lapped transform, a quantizer, a scanner and an entropy encoder. The multi-resolution lapped transform outputs transform coefficients, for example, first transform coefficients and second transform coefficients. A multi-resolution representation can be obtained utilizing second transform coefficients of the multi-resolution lapped transform. The color space mapper maps an input image to a color space representation of the input image. The color space representation of the input image is then provided to the multi-resolution lapped transform. The quantizer receives the first transform coefficients and/or the second transform coefficients and provides an output of quantized coefficients for use by the scanner and/or the entropy encoder. The scanner scans the quantized coefficients in order to produce a one-dimensional vector for use by the entropy encoder. The entropy encoder encodes the quantized coefficients received from the quantizer and/or the scanner resulting in data compression.

摘要： A print data method includes a slicing step, a compressing step and decompressing step. The slicing step divides a swatch of data to be printed and required by each motor movement into a plurality of slices, each having m bits to represent printed pixels and further divided into n segments, where m, n are integers. The compressing step uses an inter-slice compression to represent an (i+1)-th slice of data on a basis of an i-th slice of data for generating a compressed (i+1)-th slice of data and an (i+1)-th control character. The decompressing step uses an inter-slice decompression with respect to the inter-slice compression to restore the (i+1)-th slice of data from the compressed (i+1)-th slice of data for further printing.

摘要： A method of compressing a set of image data organized into a matrix of pixels includes selecting a multi-pixel block portion of the data, then performing a mathematical function on the multi-pixel block portion to generate a first result. The multi-pixel block portion is divided into at least two segments, and a function is performed on each of the segments to generate a second result and a third result. Based on a comparison of the first, second, and third results, determining whether or not to compress the multi-pixel block portion. The function may be a deviation or mean measurement and serve to determine the noise level and image detail level to determine whether to compress or divide the block into sub blocks. Sub blocks may be recursively analyzed for compression or subdivision until all sub blocks are compressed or divided into single pixels.
