Specifies a zoom factor for rectangle copies and writes.
FORTRAN (libfgl.a)
void rectzoom(Float32 xfactor, Float32 yfactor)
SUBROUTINE RECTZO(xfactor, yfactor) REAL xfactor, yfactor
The rectzoom subroutine specifies independent x and y zoom factors that the rectcopy and rectwrite subroutines use. Float values are rounded to the nearest integer.
The default value for the xfactor and yfactor parameters is 1.0.
Note: This subroutine cannot be used to add to a display list.
| xfactor | Specifies the multiplier of the rectangle in the x direction. |
| yfactor | Specifies the multiplier of the rectangle in the y direction. |
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. |
