NAME

make_picture_current − output buffered primitives to display

SYNOPSIS

C Syntax:

void make_picture_current(fildes);
int fildes;

FORTRAN77 Syntax:

subroutine make_picture_current(fildes)
integer*4 fildes

Pascal Syntax:

procedure make_picture_current(fildes:integer);

DESCRIPTION

Input Parameters

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

Discussion

Make_picture_current outputs any previous primitives that may still be in the device or driver buffers to the display device fildes.  It is commonly used:

• in interactive graphics sessions at points where the operator must see the entire image in order to proceed,

• or in hard-copy graphics at the end of the picture generation process such as when transferring an image from the raster buffer to the printed page in a buffered raster printer. 

Gclose also performs a make_picture_current operation before closing the device.
