Name of Program
graphical kernel system (GKS)
interactive generation of graphics
interactive modification of graphics
reading and displaying of graphics stored in GKS-metafiles (GKSM)
writing of newly generated or interactively modified graphics to a GKS-metafile (GKSM) or CG-metafile (CGM)
Short Description of Functionality
The program EDITOR serves as a graphical postprocessor to interactively generate simple computer graphics. Furthermore it may be used to read and display graphics stored in GKS-metafiles (GKSM). If graphics consist out of GKS-segments they can be interactively modified in different ways. The following actions are possible:
insertion of GKS output primitives:
- areas and
- generalized drawing primitives (GDP).
- For all primitives mentioned the related attributes (e.g. colour) can be appropriately set by the user.
- deletion of GKS segments (segments may contain a smaller or larger number of GKS output primitives).
- interactive zooming.
- transformations for graphical informations stored in GKS segments. The following actions are defined:
- scaling (also distortion possible) and
Operations can be executed for a single segment as well as for a group of segments.
- reading GKS-metafiles (GKSM).
- writing GKS-metafiles (GKSM) and CG-metafiles (CGM).
- writing of files with type layout.dat.
Display of some GKS Software Precision Fonts scaled normal-proportional. This graphis is also available in a GKS-METAFILE.
- GKS-metafile (GKSM)
- GKS-metafile (GKSM)
- CG-metafile (CGM)
- layout file (filetype layout.dat)
The program makes intensive use of GKS features like the workstation independent segment storage (WISS) as well as different methods for interactive input.
The GKS-editor of the program EDITOR is stored in a subroutine which is part of many GKS graphical programs used at BAW.
