Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To obtain a plotting device with which the simplification and speed up of conversion processing are possible by executing conversion of a dot number and line number by using a conversion table. SOLUTION: First 6-bits are read from a source pattern and these 6-bits are handled as an address data for accessing a transverse direction 240/400 conversion table (T6). Whether the plotting result after the conversion is the black bit priority processing stressing a black dot to an extremely small size or not is then judged by the instruction on the data from an upper position or memory switch information (T7). If the result is the black pit priority processing, a black pit priority table TC is accessed and a conversion pattern of 10-bits is extracted (T8). If the result is not the black pit priority processing, an ordinary table TB is accessed and the conversion pattern of 10-bits is extracted (T9). The extracted conversion pattern is then written into the test addresses and the source pattern is updated by 6-bits and the test address is updated by 10-bits (T10).
