PUSH_VDC_MATRIX(3G)

NAME

push_vdc_matrix − push the vdc-to-device units transformation matrix onto the top of the matrix stack.

SYNOPSIS

C SYNTAX

void push_vdc_matrix(fildes);
int fildes;

FORTRAN77 SYNTAX

subroutine push_vdc_matrix(fildes)
integer*4 fildes

PASCAL SYNTAX

procedure push_vdc_matrix(fildes:integer);

HP-UX COMPATIBILITY

Level: HP-UX/STANDARD

Origin: HP

DESCRIPTION

INPUT PARAMETERS

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

DISCUSSION

A copy of the current vdc-to-device units transformation matrix is pushed onto the top of the matrix stack and becomes the current transformation matrix. If vdc_extent, set_p1_p2, mapping_mode, or viewport_justification changes, the vdc-to-device units transformation matrix at the bottom of the matrix stack changes but not any vdc matrices that were pushed using push_vdc_matrix.
