Attributes

At a minimum, ePiX must be told how large the printed figure will be, and how large a Cartesian rectangle to allocate. The preamble must contain enough information to create a working state. In the body of an input file, the ``drawing state'' determines the figure's appearance. Attributes are declarations, set by commands that accept arguments of the stated type, possibly void. Color and path width are controlled by writing L^ATEX commands to the output file immediately; the remaining attributes are managed internally.

• Angular mode: radians(), degrees(), or revolutions().

• Path thickness: plain(), bold(), pen(double).

• Path style:
  • solid()
  • dashed(double). Optional argument is the dash density, the fraction (0.05-0.95) of the path taken up by dashes.
  • dotted(double). Optional argument is the diameter (in pt) of a dot.
  The commands dash_length(double) and dot_sep(double) set the distance (in pt) between vertices of a dashed or dotted path.

• Color: rgb(densities), cmyk(densities), primary(density).

• Filling: fill(bool), argument defaults to true.
  • Gray depth: gray(double), 0=white, 1=black.
  • PSTricks (q.v.) filling style, fill color.

• Text rotation: label_angle(double)

• Clipping and cropping (q.v.)

• Camera (q.v.)
