A segment is any object described by GKS commands and data that start with CREATE SEGMENT and Terminates with CLOSE SEGMENT command. What functions can be performed on these segments ?
Translation, Rotation, Panning and Zooming
In the Graphical Kernel System (GKS), picture components are grouped into segments: everything defined between CREATE SEGMENT and CLOSE SEGMENT is stored as one named unit that can later be manipulated as a whole without redrawing it from scratch.
Segments carry a segment transformation and attributes, so a stored segment can be translated (moved to a new position) and rotated about a point. Because segments are kept in the segment store and displayed through the viewing pipeline, the picture made up of segments can also be panned (the window moved across the scene) and zoomed (the window enlarged or reduced) by changing the viewing transformation, with the segments simply being re-displayed.
So the full set of functions that can be performed on these segments is translation, rotation, panning and zooming. The choices naming only translation and rotation, or only panning and zooming, each list just part of the supported operations, and scaling with shearing is not the pair of segment functions this description refers to.
Translation, Rotation, Panning and Zooming option is correct.
