NAME

hatch_spacing, inthatch_spacing − specify spacing between hatch lines

SYNOPSIS

C Syntax:

void hatch_spacing ( fildes, spacing, mode )
int fildes, mode;
float spacing;

void inthatch_spacing ( fildes, spacing, mode )
int fildes, spacing, mode;

FORTRAN77 Syntax:

subroutine hatch_spacing ( fildes, spacing, mode )
integer*4 fildes, mode
real spacing

subroutine inthatch_spacing ( fildes, spacing, mode )
integer*4 fildes, spacing, mode

Pascal Syntax:

procedure hatch_spacing ( fildes:integer; spacing:real;
mode:integer );

procedure inthatch_spacing ( fildes, spacing, mode:integer );

DESCRIPTION

Input Parameters

fildes Integer file descriptor returned by gopen when an I/O path to a graphics device is opened. 

spacing is the spacing between hatchlines in coordinates indicated by mode.

mode is one of: DC_UNITS, VDC_UNITS, MC_UNITS. 
 

Discussion

Hatch_spacing allows the user to specify the distance between adjacent hatchlines, measured in the direction perpendicular to the hatchlines.  Mode specifies what units spacing is in; DC_UNITS if spacing is in device coordinates;  VDC_UNITS if spacing is in virtual device coordinates; and MC_UNITS if spacing is in modeling coordinates. 

Defaults

spacing =1/32 of the default vdc_extent x-axis. 

mode = VDC_UNITS.
