Note Note Logical Operation Command Specifies the logical operation to be performed in RGB color space on the destination, source and texture to produce new destination data. ?*l#O # = Logical operation value (see Table 2-6) Default = 252 (TSo) Range = 0 to 255 When source and/or pattern transparency modes are set opaque (not defaulted), values specified by this command map directly to the ROP3 (raster operation) table values on the following page. However, when source and/or pattern transparency modes are set transparent, the additional operations shown on the previous page must be performed to achieve the final result. Logical operations in the table are shown in RPN (reverse polish notation). For example, the value 225 corresponds to TDSoxn, the logical function of NOT (texture XOR (source OR destination)) This command is the PCL Version of the HP-GL/2 MC command. This command sets the ROP value which affects not only PCL operation but also the HP-GL/2 ROP value. 2-16 Printer-Specific Differences ENWW
