SYNOPSIS

C Syntax:

void cgm_to_starbase(fildes,source,picture_number);
int fildes,picture_number;
char *source;

FORTRAN77 Syntax:

subroutine cgm_to_starbase(fildes,source,picture_number)
integer*4 fildes,picture_number
character*(*) source

Pascal Syntax:

procedure cgm_to_starbase (fildes: integer;var source: string255;picture_number: integer);

DESCRIPTION

Input Parameters

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

source Pathname of the cgm file.

picture_number
Picture number in metafile to be interpreted.

Discussion

CGM is a graphical data base suitable for the storage and retrieval of picture information in a way that is compatible between devices of differing capabilities and design.

Cgm_to_starbase reads the cgm file specified by source and interprets pictures in the metafile by converting cgm elements into starbase. The picture, picture_number, is interpreted and output to the device specified by fildes. The first picture in the cgm corresponds to picture_number, equal to one. The second picture in the cgm corresponds to picture_number, equal to two, and so on up to the number of pictures in the metafile. inquire_cgm can be called to obtain the number of pictures in the metafile as well as other information about the metafile.

/usr/lib/libsbcgm.a must be linked to this program. See CGM in the Starbase Graphics Techniques manual
