摘要： A method for encoding and decoding digital image data, includes the steps of: testing the data for a vertical relationship between adjacent lines of the image; generating directly a reference code word representative of the vertical relationship for each successful test; generating by table lookup a run code word for a stream of data bits of common value for each unsuccessful test whereby a data element representing a number of bits in a code word is stored at a predetermined offset from a table entry for the code word; merging the vertical reference code words and the run code words generated by the above steps to form an encoded data stream; testing the encoded data stream for a reference code; decoding directly the vertical relationship from the reference code for each successful test; decoding by table lookup a run of bits of common value by serial examination of said encoded data stream for each unsuccessful test; and storing data decoded by the above steps in a predetermined relationship. A fast algorithm for modifying an image in run representation form before encoding or after decoding is also described.

摘要： A system for formatting electronic binary image data, which may be in compressed raster form, into transposed or rotated raster form for storage or output, such as on a printing device, is disclosed wherein the image data is first assembled in a buffer in the form of vectors of run ends representing successive raster scan lines of an original image to be reproduced. The elements of an intermediate buffer are initialized to zero and the data is entered into the intermediate buffer by using each run end to set a bit in the intermediate buffer, with the bits being set in the buffer elements in correspondence with the respective raster positions of the run ends. The elements of the intermediate buffer containing the entered electronic data are then combined, such as by EXCLUSIVE-ORing, to create transposed or rotated raster data, which may stored or input to a suitable output device, such as a printer or display. The raster data may be compressed in the process and other processes, such as image reversal, may be carried out with facility.

摘要： A method and apparatus for converting an image in run representation form into a raster image which is rotated by some multiple of 90.degree. from the orientation of the original image is disclosed wherein the original image data which is stored in run end or run length form may be divided and stored in discontiguous blocks. In implementing a 90.degree. rotation, the image data is conceptually divided into vertical strips, each of which is independently rotated to create a horizontal strip of the output image. The rotation process is carried out by firstly converting the run representation image data to raster form, dividing the data in each row among a number of intermediate buffers, each of which contains the data from one vertical strip of the original image. The contents of each buffer are rotated and rearranged in an available buffer to form a horizontal strip of the rotated image ready for raster readout. Similarly, a convenient method of rotating the input image 180.degree. is also described wherein the original image is read in run representation form a row at a time and the rows are converted to raster form and placed in storage in reverse order, with the order of the bits in each row also reversed.
