Abstract

This article describes a method for integrating graphics development across system environments to provide unified graphical development in an integrated mainframe host-intelligent workstation (IWS) environment. Advances in high resolution graphics and all-points-addressable (APA) printing, coupled with the high availability, decreasing cost, and the increasing usability of graphical hardware and software tools and techniques are making it possible for more computer users to produce quality graphics on desktop IWS as well as on mainframe computing systems. d However, because of differences in the basic operation of IWS and hosts, the implementation of a graphics system on an IWS can differ drastically from that on a host.

Intelligent Workstation to Host Graphic Data Migration

This article describes a method for integrating graphics development across system environments to provide unified graphical development in an integrated mainframe host-intelligent workstation (IWS) environment. Advances in high resolution graphics and all-points-addressable (APA) printing, coupled with the high availability, decreasing cost, and the increasing usability of graphical hardware and software tools and techniques are making it possible for more computer users to produce quality graphics on desktop IWS as well as on mainframe computing systems. d However, because of differences in the basic operation of IWS and hosts, the implementation of a graphics system on an IWS can differ drastically from that on a host. This results in duplicated and wasted efforts in preparing graphics in which the graphical data is required for use in both the IWS and host. The present method is a program which transforms the graphical output from an IWS design and analysis tool to a host graphical format. The IWS tool creates an intermediate graphics file, termed a metafile, which is a graphic descriptor file containing both vector and text information. The program transforms these metafiles into files which can be displayed or printed on host graphics devices and printers. The IWS metafile is transformed into a host graphical file for the intended output device. The host devices typically supported are the IBM 3277 display with the graphics attachment, 3279 graphics displays, 3287 color graphics printer, 3800 models 3 and 8, 3820, and 4250 APA printer. Both LIST and PSEG files may be created for APA printers so that graphical document fragments can be printed directly or can be included as part of documents being produced with DCF/Script and/or ISIL. The graphic files may be rotated 90 degrees clockwise for all devices. See the figure for an example of the output that can be expected. The algorithm used to displ...
