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.

摘要： A dental care kit for simulating a visit of a fictional tooth fairy and instructing a child of the importance of proper dental care. The inventive kit includes a storage chest containing a plurality of envelopes, magical fairy dust contained within a fairy dust container, an ink pad, left and right foot stamps, a coin bag, and a plurality of written notes. A method of utilizing the kit includes placing a deciduous tooth within one of the envelopes and underneath a pillow of the child's sleeping accommodations. After the child falls asleep, a parent of the child removes the tooth in the envelope for storage within the chest, sprinkles the magical fairy dust around and about the child, utilizes the left and right foot stamps and ink pad to place footprints on or about the child, places an amount of money within the coin bag underneath the pillow, and leaves one of the written notes underneath the pillow along with the coin bag. The fairy dust and footprints thus serve to convince the child of the existence of the fictional tooth fairy, while instructional indicia printed on the written notes instructs the child of the importance of proper dental care.
