innovators for industry
Ctrl Command set_angle
Function Uses a specified rotation angle to define the rotation matrix M
R
for all subsequent
coordinate transformations, see Chapter 8.2 ”Coordinate Transformations”, page 224.
Call set_angle( HeadNo, Angle, at_once )
Parameters HeadNo Number of the scan head connector. As an unsigned 32-bit value.
= 1: The definition only affects the first scan head connector.
= 2: The definition only affects the second scan head connector.
= 0, 3: The definition affects both scan head connectors.
= 4: The definition affects the virtual Image Field (see also comments).
Only the 3 least significant bits are evaluated.
Angle Rotation angle. In degrees.
As a 64-bit IEEE floating point value.
Positive angles result in a counterclockwise rotation around the centerpoint of
the Image Field.
at_once Determines when the defined transformation becomes effective.
As an unsigned 32-bit value.
Like set_matrix.
Comments • See also Chapter 8.2 ”Coordinate Transformations”, page 224.
• As of DLL 617, OUT 617 the following applies for HeadNo = 4: The global coordinate
transformations are generally available, even outside a Processing-on-the-fly Session.
RTC4RTC6 New command.
RTC5RTC6 Unchanged functionality.
Version info Last change DLL 617, OUT 617: HeadNo = 4.
