Other Changes

• The use of MARGIN parameters to determine the width of the margins to place around annotated axes has been changed. The widths of the margins used to be specified as fractions of the height or width of the corresponding DATA plot. They are now given as fractions of the height or width of the current picture. Applications affected include CONTOUR, DISPLAY, LINPLOT.

• A bug has been fixed in the random number generators which could cause the same set of random numbers to be used on succesive invocations of an application, if the invocations occurred within one second of each other. For instance, if CREFRAME were used twice to create two small frames of Gaussian noise with no delay inbetween, then the resulting images could previously have been identical. Another affected application is CENTROID; estimates of the variance of the centroid positions will now be rather different because previous estimates were based on correlated random shifts.

• Several significant memory leaks have been fixed.

• The WCS information stored with each picture in the graphics database now includes a Frame with Domain CURPIC which represents normalized co-ordinates with in each individual picture.

• Defaults for style parameters can now be set for individual applications. See here.

• The following applications have been converted to use the GKS version of PGPLOT instead of SGS/NCAR (there are no changes in functionality): GDNAMES, GDCLEAR, IDCLEAR, OVCLEAR, GDSET, IDSET, OVSET, PALENTRY, PALDEF, PALSAVE, PALREAD.

• The implementation of dynamic defaults for parameters has been changed. These were previously indicated in the reference documentation by an empty default at the end of the parameter description (i.e. []). Such parameters have been changed so that they now have a null value [!] for the default. This null value is taken as an indication that the parameter should use a suitable default value. This has been necessary to enable the automatic re-invocation of applications to process groups of data files. The most noticable result of this change will probably be that the parameter values actually used are no longer stored in the application's parameter file in the user's ADAM directory, and so they cannot be obtained using PARGET for instance. This is a rather unlikely thing to want to do however!

• A bug has been fixed which could prevent numerical axis labels from appearing when a set of annotated axes is drawn.

• The example C-shell script, multiplot.csh (see here) has been updated to work with the current version of KAPPA. It now also uses the Starlink version of PSMERGE even if another command of that name is defined.
