but used for nonstroking operations.
Set the stroking color space to
DeviceRGB
(or the
DefaultRGB
color space; see
tions. Each operand must be a number between 0.0 (minimum intensity) and 1.0
(maximum intensity).
Same as
RG
but used for nonstroking operations.
Set the stroking color space to
DeviceCMYK
(or the
DefaultCMYK
color space; see
tions. Each operand must be a number between 0.0 (zero concentration) and 1.0
(maximum concentration). The behavior of this operator is affected by the over-
print mode (see Section 4.5.6, “Overprint Control”).

Invoking operators that specify colors or other color-related parameters in the
graphics state is restricted in certain circumstances. This restriction occurs when
