Selects a raster font for drawing text strings.
FORTRAN (libfgl.a)
void font(Int32 fontnum)
SUBROUTINE FONT(fontnum) INTEGER*4 fontnum
The font subroutine selects the raster font that the charstr subroutine uses when it draws a text string. This font remains in effect until you call the font subroutine again. Font 0 (zero) is the default.
| fontnum | Specifies a font identifier, an index into the font table built by the defrasterfont subroutine. If you specify a font number that is not defined, the system selects font 0 (zero). |
The example C language programs curved.c and font3.c use the font subroutine to select a raster font defined with the defrasterfont subroutine.
This subroutine is part of GL in the AIXwindows Environment/6000 Version 1, Release 2 with AIXwindows/3D Feature.
| /usr/include/gl/gl.h | Contains C language constant and variable type definitions for GL. |
| /usr/include/gl/fgl.h | Contains FORTRAN constant and variable type definitions for GL. |
