Specify Text Rotation Angle
$angle [degrees]
Commands in the GCT file are normally generated and maintained by FFVIEWER, and for most Graphical Customization applications it is not necessary to view or edit the GCT file.
This command is used to specify rotation of the text of the current annotation in the GCT file. The required angle is specified in degrees between -180 and 180. A positive value lifts the right-hand end of the text string and a negative value lowers the right-hand end of the text string. Annotations must be single-line, and the use of the angle command both inhibits the boxed attribute and forces transparent mode.
The annotation box should be large enough to hold the text if it were written horizontally, but the text is not clipped by the box when it is applied to the image. The center of rotation is the top left corner of the annotation box. This means that text written with a rotation value more negative than -90 appears wholly to the left of the annotation box.
The parameter on this command is used as follows:
| degrees | the angle of rotation as described above |
Example:
$angle 45
$textend "This text slants upwards"
