Graphics services provide functions required for creating, storing, retrieving and
manipulating images. These services include:
- Graphical object management services, including defining multi-dimensional
graphic objects in a form that is independent of output devices, and managing hierarchical
structures containing graphics data. Graphical data formats include two- and
three-dimensional geometric drawings as well as images.
- Drawing services support the creation and manipulation of images with software
such as GKS, PEX, PHIGS or OpenGL.
The following functional areas are currently supported mainly by applications, but are
progressing towards migration into the Application Platform:
- Imaging functions providing for the scan, creation, edit, compression and
decompression of images in accordance with recognized image formatting standards. For
example: PIKS/IPI, OpenXIL or XIE.
