If you do not need interactivity
such as changing the chart type or style, the JAVAIMG and ACTXIMG
devices provide several advantages over the interactive presentations
that are generated with the JAVA and ACTIVEX devices. Because PNG
image files are generated, the Web clients are not required to access
the Java run-time environment or install the
SAS/GRAPH ActiveX Control to display the graphs.
Also, Web performance improves because the PNG image files are smaller
in size than the HTML files that are required to run an applet or
an ActiveX control.
Note: The ACTXIMG device cannot
be used with the ODS PDF, PCL, PS, or PRINTER destinations on 64-bit
computers. The
SAS/GRAPH
software uses the JAVAIMG device instead.
Some of the
SAS/GRAPH procedures, such as the GKPI and
GEAREABAR procedures, support only the JAVA, JAVAIMG, ACTIVEX, and
ACTXIMG devices. For these procedures, you must use the JAVAIMG or
the ACTXIMG device if you need a static image.
Finally, in some cases
such as plots generated with the G3D procedure, the ACTXIMG and JAVAIMG
devices provide a better static image than the other devices.
Note: When SAS is installed on
a server, the ACTXIMG and JAVAIMG devices are limited by the display
capabilities of the server on which they run—for example, the
number of colors that the server is capable of. Consequently, the
ACTXIMG or JAVAIMG PNG snapshot might not look as good as what you
get from the JAVA and ACTIVEX devices. Therefore, it is better to
use the JAVA or ACTIVEX device if the server's display settings are
less than optimal.
