Changes Introduced in V5.6-0

The following describes the most significant changes which occurred in the AST library between versions V5.5-0 and V5.6-0:

  1. New functions astBBufastBBuf and astEBufastEBuf have been added to the PlotPlot class. These control the buffering of graphical output produced by other Plot methods.

  2. New functions astGBBuf and astGEBuf have been added to the interface defined by file grf.h. The ast_linkast_link command has been modified so that the -grf_v3.2 switch loads dummy versions of the new grf functions. This means that applications that use the -grf_v3.2 switch should continue to build without any change. However, the new public functions astBBuf and astEBuf will report an error unless the new grf functions are implemented. If you choose to implement them, you should modify your linking procedure to use the -grf (or -grf_v5.6 ) switch in place of the older -grf_v3.2 switch. See the description of the ast_link command for details of these switches.

  3. New method astGetRegionMeshastGetRegionMesh returns a set of positions covering the boundary, or volume, of a supplied RegionRegion.
