Object Definition
The discipline_attribute_number, group_attribute_number, and
object_id_attribute_number are 2-byte integers with a value equal to the value in
Table C-2 on page C-3. The attribute_length is a 4-byte integer, and
attribute_value is an ASCII string with the length specified by the attribute_length
value.
The color_attribute is either a symbolic value in which a color name previously
defined in the color definition section is used or a literal value in which the actual
RGB values are specified.
The following is the format for the symbolic color attribute:
color_attribute_number
symbolic_color_type_number
attribute_length
attribute_value
In this format, the color_attribute_number is a 2-byte integer with a value equal to
the value in Table C-3, “Object Attribute Numbers and their Values” on page C-8
and symbolic_color_type_number is a 2-byte integer with a value equal to the
value in Table C-4, “Color Type Number and their Values” on page C-10,
attribute_length is a 4-byte integer, and attribute_value is a ASCII string
specifying a color name previously defined with length specified by the attribute
length value.
The following is the format for the literal color attribute:
color_attribute_number
literal_color_type_number
red_value green_value blue_value
In this format, the color_attribute_number is a 2-byte integer with a value equal to
the value in Table C-3, “Object Attribute Numbers and their Values” on page C-8
and the literal color attribute is a 2-byte integer with a value equal to the value in
Table C-4, “Color Type Number and their Values” on page C-10, and red_value,
green_value, and blue_value are 4-byte single-precision floating-point numbers
that represent red, green, and blue values (RGB), in that order. Valid RGB values
range from 0.0 to 1.0, where 1.0 represents the highest value allowable.
