PHIGS STATE

EFFECT

A source region can be defined by giving a view index, or a rectangle in NPC or DC.

If a view index is given, the rectangle used is the viewport limit of the view.

If the destination target is the display target, visual effect is immediate. The display surface is set to the source target.

ERRORS

3

Ignoring function, function requires state (PHOP, WSOP,*,*)

115

Ignoring function, the specified view index is less than one

150

Ignoring function, setting this view table entry would exceed the maximum number of entries allowed in the workstation view table.

3001

Ignoring function, the first target does not exist

3002

Ignoring function, the second target does not exist
