From PostScript® language reference

rectclip x y width height rectclip –
numarray rectclip –
numstring rectclip –
intersects the area inside the current clipping path with a rectangular 
path defined
by the operands to produce a new, smaller clipping path. In the first 
form, the operands
are four numbers that define a single rectangle. In the other two forms, the
operand is an array or an encoded number string that defines an 
arbitrary number
of rectangles (see Sections 3.14.5, “Encoded Number Strings,” and 4.6.5,
“Rectangles”). ***After computing the new clipping path, rectclip clears 
the current
path with an implicit newpath operation.***
