Argument

None

Code Sample Example

In this example, the current position is set first and saved.

gsave and grestore are required to be issued in pairs, meaning that you need the equal number of gsave and grestore

commands to run in any given object. However, an uneven number of commands can be located in the code, if some of them

are within IFstatements, so that when the code is actually run, the pairing occurs correctly in all instances.

Example

moveto( 1, 1 )

%Position is now 1,1

gsave()

%Save current state

lineto( 2, 1 )

%Position is now 2,1

lineto( 2, 2 )

%Position is now 2,2

grestore()

%Restore previous state: position is now 1,1
