574.0. "Windows Turn Green After Sixel File Display" by IAMOK::ALLEN () Tue Apr 11 1989 12:50

    
    
    Would anybody happen to know why all the other terminal windows
    turn to an awfull unviewable green color when I try "$TYPING" a
    sixel file from a terminal window?  Besides the other terminal windows
    turning to the unsightly green color the entire background turns
    to a sort of purple color.  To get the colors back to normal I have
    to kill the terminal window where the sixel file was displayed.
    Any way of avoiding this problem?

	Re: .0 Let me guess: you have a 4-plane GPX. DECterm is trying to emulate a 16 color (4 plane) terminal on a 16 color (4 plane) workstation. This means that it has to take over the entire workstation if it wants to display graphics. (Actually there are some tricks it could have played, but there wasn't enough time to get too fancy). When you display a ReGIS or sixel file your entire screen will switch to the VT340 default colormap, as modified by the ReGIS or sixel file. To return to the default colormap, you need to clear the window (so DECterm know that there are no visible graphics) and then reset it (so DECterm knows it's using the default text colors). You can do this by selecting Clear Display followed by Reset Terminal from the Commands menu. This should improve in V2, but the fundamental problem remains, i.e. you can't display a 16 color application in its true colors without affecting colors in other windows. -- Bob

Re: .0

Let me guess: you have a 4-plane GPX.

DECterm is trying to emulate a 16 color (4 plane) terminal on a 16 color (4
plane) workstation.  This means that it has to take over the entire workstation
if it wants to display graphics.  (Actually there are some tricks it could have
played, but there wasn't enough time to get too fancy).

When you display a ReGIS or sixel file your entire screen will switch to the
VT340 default colormap, as modified by the ReGIS or sixel file.  To return
to the default colormap, you need to clear the window (so DECterm know that
there are no visible graphics) and then reset it (so DECterm knows it's using
the default text colors).  You can do this by selecting Clear Display
followed by Reset Terminal from the Commands menu.

This should improve in V2, but the fundamental problem remains, i.e. you can't
display a 16 color application in its true colors without affecting colors
in other windows.
