Syntax

PSEWSC (EWIDTH)

Argument       Data Type      Access     Description
---------------------------------------------------------------------------
EWIDTH         Real           Read       Edge width scale factor.  The
                                         default value is 1.0.

Description

PSEWSC specifies the edge width scale factor to be applied to the workstation’s nominal edge width.  Depending on the current edit mode, this function either inserts the new structure element directly after the element indicated by the pointer or replaces the element indicated by the pointer. The pointer then points to the new set edge width scale factor element. 

The set edge width scale factor element has the following effects during structure traversal:

•Digital PHIGS sets the current edge width scale factor entry in the PHIGS traversal state list to the specified value.  If the current edge width scale factor ASF entry is INDIVIDUAL, Digital PHIGS uses this value during the subsequent traversal of the following primitives:

•Fill area set

•Fill area set 3

•Fill area set with data

•Quadrilateral mesh with data

•Set of fill area set with data

•Triangle set with data

•Triangle strip with data

If the corresponding ASF is BUNDLED, the value has no effect. 

•Digital PHIGS applies the edge width scale factor to the workstation’s nominal edge width, and maps the resulting value to the closest value available on the workstation. 

If Digital PHIGS is in immediate mode, it performs this function immediately, but the function does not create a structure element.
