Specview requirementsSpecview is 100% written in Java and is distributed in standalone application, and applet, formats. The application version requires that either the Java Development Kit (JDK) or Java Runtime Environment (JRE) be installed in your system and accessible from your path. For the applet version, see here. Specview Version 2.14.2 was tested under these configurations:
For Mac OS X issues, see below. You can check if you have access to the proper JDK or JRE by typing the command java -version at a command line window (a.k.a. "DOS prompt" or "Command prompt" window under Windows). Specview is also distributed as bundled software in the Star View astronomical database browser and analysis tool ( http://starview.stsci.edu). If you have Star View version 7.1 or above already installed, you automatically got Specview as Star View's spectral preview tool.
Mac support:Specview was tested under Mac OS X (v10.4.11) with Java version 5.0 but results were not satisfactory. It appears that the current Mac OS support for XOR graphics mode suffers from timing / synchronization problems. The main result is that the cross-hair cursor does not behave properly, flashing and leaving behind a lot of garbage when moved around on screen. When running under Mac OS X, Specview turns off the cross hair cursor by default. If desired, it can be put back to life using the Cursor menu. Some generic plot operations end up leaving behind little pieces of garbage on screen. These can be removed by forcing a screen redraw (by a resize, or minimization-maximization). Aside from these graphics problems, Specview seems to work as expected under Mac OS. Performance can be significantly worse than under Windows or Linux, but the main culprit seems to be again the Java graphics implementation. CPU-bound tasks run at a similar speed as they run on a comparable (clock) Windows or Linux machine. Users running Leopard 10.5 reported extreme slowness in screen updates. |
