Name
pset_back_int_style − Specifies the back interior style for drawing back-facing portions of area primitives.

Pint_style style /∗ (I) Back interior style ∗/
)
Data Structures
typedef enum {
PSTYLE_HOLLOW, /∗ hollow interior ∗/

PSTYLE_EMPTY /∗ empty interior ∗/
} Pint_style;
Description
pset_back_int_style specifies the back interior style that Digital PHIGS uses to draw back-facing portions of area primitives. Depending on the edit mode, this function either inserts the new structure element directly after the pointer or replaces the element indicated by the pointer. The pointer then points to the new set back interior style element.
The following back interior styles determine the style in which Digital PHIGS fills the interior or back-facing area-defining primitives:
Style Method
-------------------------------------------------------------------------
HOLLOW Draws the boundary using the colors resulting from
the rendering pipeline. Does not fill. Line width and
line type are implementation-dependent.
SOLID Fills the interior using the colors resulting from the
rendering pipeline.
PATTERN Fills the interior using the colors resulting from the
rendering pipeline. Uses the current back interior
style index (sometimes referred to as the pattern
index in this context) to select a pattern from the
pattern table. This value must be greater than 0.
HATCH Fills the interior using the colors resulting from the
rendering pipeline. Uses the current back interior
style index (sometimes referred to as the pattern
index in this context) to select a hatch from the
hatch table. This value must be greater than 0.
EMPTY Area-defining primitives using this value are visible
only if the edge flag is set to ON. Does not fill.
-------------------------------------------------------------------------
If Digital PHIGS is in immediate mode, it performs this function immediately, but the function does not create a structure element.
