Purpose

Specifies pixel values that are added to a window.

Libraries

FORTRAN Syntax

SUBROUTINE FUDGE(xfudge, yfudge)
INTEGER*4 xfudge, yfudge

Description

The fudge subroutine specifies pixel values that are added to the dimensions of a window when it is sized. Typically, this subroutine is used to create interior window borders. Call the fudge subroutine before calling the winopen subroutine.

The fudge subroutine is useful in conjunction with the stepunit and keepaspect subroutines. With the stepunit subroutine, the window size for integers m and n is:

width = xunit * m + xfudge
height = yunit * n + yfudge

With the keepaspect subroutine the window size is (width, height), where:

(width - xfudge) * yaspect = (height - yfudge) * xaspect

Note: This subroutine cannot be used to add to a display list.

Parameters

Implementation Specifics

This subroutine is part of GL in the AIXwindows Environment/6000 Version 1, Release 2 with AIXwindows/3D Feature.
