PURPOSE:To perform the high speed plotting in a buffer memory by repeating the operations of plotting on sections not yet plotted by means of half-tone vector data formed at the time of plotting to a band buffer and printing. CONSTITUTION:All vectors are classified into bands #1 to #N by the operation S101, and then a band buffer X is set as A by S102 and a band buffer Y is set as B. A half-fector table is cleared at the time of initial processing and the operation is transferred to a loop 101. The inside of band buffer is cleared by S104 and the operation is transferred to a loop 102, while the operation is transferred to a loop 103 as the half vector is not in the processing of first band. Vector data waiting for the start of printing is loaded from a memory into a band #1 in the loop 103, and the sections of band #1 of the areas represented by the vector are smeared away on all scanning lines one by one. The operation represents the process of S109. |
