For accurate ReGIS and sixel graphics emulation using Reflection, on thetab from the dialog box, the should be set to one of the four graphics terminal types: VT240, VT241, VT330, or VT340.
The VT240 and VT330 are monochrome graphics terminals, providing up to four shades of gray at once.
The VT241 and VT340 are color graphics terminals; the VT241 provides up to four different colors at once, while the VT340 provides up to 16 different colors.
Setting your display to 256 colors is highly recommended.
All four graphics terminals support ReGIS. However, each terminal differs slightly in its implementation of ReGIS. Reflection should be set for the same type of terminal as that of the host graphics program.
A host program may need to determine the graphics capabilities of Reflection. It does so by requesting the(which is set on the tab from the dialog box). For accurate graphics emulation, the should be set to the type of terminal the host expects to find: VT240, VT241, VT330, or VT340 (the default is VT320).
NOTE:Changing theresets all associated settings (that is, any setting from the dialog box or the dialog box).
