Color handling under +Sun X11/NeWS has been fixed, preventing a lot of miscoloring and some +crashes on that platform. A bug which resulted in crashes with long +lists of circular polymarkers under the 'xws' device driver has been +fixed. (Both of these fixes are in the 'xws' driver, and not DrawCGM +proper). The CGRID and CIRCLE routines have been added to draw +circles and coordinate grids respectively, and the OUTFIL routine +has been added to allow setting of the output file name. + + INTALLATION INSTRUCTIONS + +This software is designed to run on VMS systems, and Unix systems +including UNICOS and Ultrix. To install the software under VMS, +copy the GPlot directory tree to the VMS machine and edit the +descrip.mms file in the main (gplot) directory to include the device +drivers and GPlot controllers you want. Use the following command +to cause VAX MMS to create the DrawCGM library and the four test +routines cgmgen_test.exe, drawcgm_test.exe, drawcgm_tst2.exe, and +clip_test.exe: + + $ mms drawcgm.olb tests + +On Unix systems, untar or copy the GPlot directory tree and edit the +Makefile in the main (gplot) directory to accomodate your machine and +include the device drivers and controllers you want. The following +command will cause make to create the DrawCGM library and the four test +programs listed above: + + $ make drawcgm tests + +If you are using the Vax C compiler, you may need to compile and include +the .jbl files included in the distribution to properly resolve entry points +referenced from FORTRAN but resolved from C. If you have this problem, +simply compile the .jbl files and merge them into the DrawCGM object library. + +The descrip.mms and Makefile files can also be used to make GPlot, of +course. + + HINTS + +The most trouble-prone part of the current implementation is the +system used to cause pauses at the end of frames when DrawCGM is +used interactively. In general, if STPAUS has been called, at the +end of each frame (in response to NEWFRM or GRFCLS) the terminal +bell will ring and the program will wait for the user to hit return +before continuing. This works fine in most cases, but on the Cray +under UNICOS, a carriage return is not sufficient to continue at +the end of a frame. Use a space followed by a carriage return +instead. This is a consequence of the behavior of Cray CFT77 +Fortran. + + + -- cgit v1.2.3
