SYNOPSIS
subroutine textslant(var) real var
DESCRIPTION
Defines the obliqueness of the fonts. This is a simplistic method that allows you to generate italicized versions of the software fonts. The x- values of the software font coordinates after the current textsize() values are applied are multiplied by (1+val).
Note that this means the same value tilts the characters less the taller the characters are relative to their width.
Generally, practical values are generally between -1 and 1 times the
EXAMPLE
Sample program:
program demo_textslant use M_draw implicit none real :: x1, x2, y1, y2 real :: scl integer :: key call prefsize(1200,300) call vinit(’ ’) call color(D_BLACK) call clear() x1=0.0; x2=40.0; y1=0.0; y2=10.0; scl=3*0.7 call page(x1,x2,y1,y2) call font("times.rb") call linewidth(180) call textsize(0.8*scl,1.2*scl) call move2( x1+.3,y1+.4) call color(D_RED); call textslant(0.0); call drawstr("textslant(0.0); ") call color(D_GREEN); call textslant(-1.0); call drawstr(" textslant(-1.0);") call color(D_BLUE); call textslant(1.0); call drawstr(" textslant(1.0);") call textsize(0.8*scl,1.2*3*scl) call move2(x1+.3,y1+3+.4) call color(D_MAGENTA); call textslant(1.0); call drawstr(" textslant(1.0);") call textsize(0.8*scl,1.2*scl) call color(D_CYAN); call textslant(0.3); call drawstr(" textslant(0.3);") call color(D_WHITE); call textslant(0.5); call drawstr(" textslant(0.5);") call vflush() key=getkey() call vexit() end program demo_textslant
