Section 23 G2D
(c) Description
Sets the values obtained by adding the local offset values to XC and YC in the current pointers.
XC and YC are set as absolute coordinates. The current pointers are used by relative drawing
commands only. After issuing a MOVE command, use relative drawing commands in succession.
If an absolute drawing command is used during this sequence, the current pointers will be used as
registers for internal computation, and the current pointer values will be lost. A MOVE command
must be therefore be issued before using relative drawing commands again.
