Intel® Fortran Compiler 16.0 User and Reference Guide
Graphics Subroutine: Sets the orientation angle of the font text output in degrees. The current orientation is used in calls to OUTGTEXT.
USE IFQWIN
CALL SETGTEXTROTATION (degree-tenths)
degree-tenths |
(Input) INTEGER(4). Angle of orientation, in tenths of degrees, of the font text output. |
The orientation of the font text output is set in tenths of degrees. Horizontal is 0°, and angles increase counterclockwise so that 900 (90°) is straight up, 1800 (180°) is upside down and left, 2700 (270°) is straight down, and so forth. If the user specifies a value greater than 3600 (360°), the subroutine takes a value equal to:
MODULO (user-specified tenths of degrees, 3600)
Although SETGTEXTROTATION accepts arguments in tenths of degrees, only increments of one full degree differ visually from each other on the screen.
Bitmap fonts cannot be rotated; TruType fonts should be used instead.
