Colours and Styles

Every graphics primitive in Draw is drawn in a specific colour and style, determined by the values of the relevant colour and style attributes.
Within the Draw database there are 20 different colour attributes and 17 style attributes, and can be classified as:
-
those for linear (line) primitives (15 linestyle and 15 colour attributes)
-
those for area primitives (one fillstyle and one colour attribute)
-
those for marker primitives (one markerstyle and one colour attribute)
-
those for text primitives (three colour attributes only).
Generally, there is a style attribute for every colour attribute, except that there are no style attributes for text primitives – only colour attributes.
The term style is used to describe the overall appearance of a line in terms of its thickness and repeating pattern, or to describe a hatching (fill) pattern, or to describe the size and appearance of markers. The full list of colour and style attributes are:

The colour attributes can be assigned values by colour table index number or by colour name. A listing of the colours is available. Refer to Colours for further information. In some circumstances colour attributes can be set to the special values: DEFAULT, TEMPLATE, UNCHANGED.
The linestyle attributes can be assigned values that describe system-defined or user-defined line styles. Refer to System-Defined Line Styles and User-Defined Line Styles for further information. In some circumstances linestyle attributes can be set to the special values: OFF, DEFAULT, TEMPLATE, UNCHANGED.
The fillstyle attribute can be assigned values that describe system-defined or user-defined fill styles. Refer to System-Defined Fill Styles and User-Defined Fill Styles for further information. In some circumstances fillstyle attributes can be set to the special values: OFF, DEFAULT, UNCHANGED.
The markerstyle attribute can be assigned values that describe system-defined marker styles. Refer to Marker Styles for further information. In some circumstances markerstyle attributes can be set to the special values: OFF, DEFAULT.
User-defined line and fill styles are defined in the PADD database within a hierarchy headed by a STYLWL element. Refer to Draw Database Hierarchy for further information. STYLWL owns Linestyle and Fillstyle Tables (LSTYTB, FSTYTB), beneath which the definitions of user-defined Linestyles and Fillstyles are stored.
STYLWL, LSTYTB and FSTYTB are classified as ‘primary’ elements and can therefore be claimed.
The creation and maintenance of STYLWL hierarchies is the responsibility of the Draw Administrator.
