angle
Character orientation in degrees (default = 0.0)
Description
The routine gSetStrAngle() sets the current character orientation to the value in angle. The angle is measured in an anticlockwise direction from the positive x-axis.
What effect a call to gSetStrAngle() has when characters are output depends on the character mode at that time:
(a) gSetHardCharSize()
Call to gSetStrAngle() has no effect
(b) gSetHardChars()
Characters are drawn at the correct orientation if possible, otherwise they are stepped
(c) gSetMixedChars()
Character orientation may differ by up to 1 degree from the requested orientation
(d) gSetSoftChars()
Characters are angled exactly as requested
(e) gSetCharTransformMode(GON)
Characters are angled as requested and transformed, so orientation may be modified by the current rotation.
