Topics in this section

• Use Special Codes

  The second character of the three-character string (the vector length specification) must be 0, or you can specify the special code number. For example, 008 and 8 are both valid specifications.

• Codes 0, 1, and 2: End of Shape and Draw Mode Control

  Code 0 marks the end of the shape definition, and Codes 1 and 2 control Draw mode.

• Codes 3 and 4: Size Control

  Codes 3 and 4 control the relative size of each vector.

• Codes 5 and 6: Location Save/Restore

  Code 5 pushes (saves) and code 6 pops (restores) the current coordinate position while drawing a shape so that you can return to it from a later point in the shape.

• Code 7: Subshape

  Code 7 draws the subshape number given by the next byte.

• Codes 8 and 9: X-Y Displacements

  With codes 8 and 9 you can draw nonstandard vectors using X-Y displacements.

• Code 00A: Octant Arc

  Special code 00A (or 10) uses the next two specification bytes to define an arc.

• Code 00B: Fractional Arc

  Special code 00B (11) draws an arc that doesn't necessarily start and end on an octant boundary.

• Codes 00C and 00D: Bulge-Specified Arcs

  Special codes 00C and 00D (12 and 13) provide another mechanism for including arc segments in shape descriptions.

• Code 00E: Flag Vertical Text Command

  Special code 00E (14) is used only in dual-orientation text font descriptions, where the font is used in both horizontal and vertical orientations.
