Hi there,

I'm working on adding a sixel image to my board.

My problem:
It never displays the sixel.

I used img2sixel in 16 color mode, and limited the width to 300 pixels.
So I would figure bbs_display_sixel the filename and be done, but it
appears I am not.

If you call in to my board, you can see I display some text and pause,
before the pause is where the display sixel is called, with no output.

My lua:

++ SNIP 'mousemoved.lua' ++
bbs_write_string("Hi Sixel\r\n") bbs_write_string("/talisman/"..bbs_get_data_path().."/mouse_moved.sixel\r\n
"
)


bbs_display_sixel("/talisman/"..bbs_get_data_path().."/mouse_moved.sixel")
-- SNIP --

If you're trying to follow along, the first 2 lines are just writing,
the last line, with a space between the first 2 is the actual call I'm
wrestling with.

I have mouse_moved.sixel the name of the sixel file in the scripts data folder (just for lack of better location to put it).

I've even tried giving it the complete 100% full path, with no luck.

Any help will be very helpful.

Take Care,
Apollo

/talisman/scripts/data/mouse_moved.sixel

It's in a Docker container, but that's the full/absolute path from within
the containers perspective.

what terminal are you using?

I've tried with Syncterm 1.1, and MagiTerm 1.1.16, which if I am correct
both support Sixel.

I've even called your board with MagiTerm and got your sixel at the end
of System Info... So that's why I know the MagiTerm definely has the Sixel support.

If you want just hit my board, you should see it before the weather. :)

yeah they should work

could it be incorrect permissions on the sixel for the bbs user?

to use it. :)

As an aside, my Syncterm doesn't work with Sixel. (I'm using Curses mode,
so perhaps I need to do the xterm -ti 340 for the Sixel to work under Syncterm?)

So I'll just keep using MagiTerm for my BBS terminal till I've played
enough with my Syncterm to figure out why it's not rendering Sixel.

Oh and for those who call, the Sixel is now randomly placed, just to
point out what I've got. (Lua rendering the Sixel in a random position)

Yup, or the X11 version (since I'm linux).

Thank you for the help.

Glade to see you're still checking in on things.

Oh I'm going to be looking to see if I can't expand the Lua Scripting to
have a bbs_user_has_sixel() so I can display a sixel and pause, or not
display a sixel and pause. (This way if sixel isn't supported, the first loginitem doesn't look like a strange pause in the middle of nothing)

For me, the key was using Curses mode. Curses doesn't do SIXEL, but SDL
does.

And depending on what features you compiled into your syncterm.
I think you can pick and choose, depending on what libraries you
install. It's been awhile since I've compiled it.

You could have an X11 only build, or a curses only. I don't think
you could get an SDL build without X11, since SDL also needs X11.

Glade to see you're still checking in on things.

"Glad". :P

Get to it! At least until they get the lobby fixed...

Do you get the screen size in lua as well? You might want to do some
math and pick an image that'll fit on the screen.

SyncTERM in non-graphics modes (e.g. curses or ANSI) doesn't do graphics (e.g. RIP, Sixel). That's expected.

There isn't an "sdl version" or an "x11 version" of SyncTERM. SyncTERM for Linux supports multiple interface/output modes. Run 'syncterm -?' to see all the options or SyncTERM->Program Settings->Video Output Mode.

Should SyncTERM send the cterm response that it supports Sixel when
in curses mode? I didn't expect it to say it supported it, when
it didn't (or more specifically couldn't).

Is this a detection issue? Is there a better way to detect Sixel support
in SyncTERM? (Or is the answer -- just don't use curses mode?!)

Ok, sorry, I thought SyncTERM was sending the same thing in curses and
non curses, but it isn't. I'll look deeper into the Sixel detection.

On 09 Jul 2023, bugz said the following...

even on linux trying to do sixel stuff in curses is wrong. curses expects to
be in full control of the terminal so it would need support added in there. but the support would likely be a function to display a whole image from a file, which would not be useful for syncterm.

I don't think so.

Here's what I'm seeing with Wireshark

From SyncTERM curses: (syncterm -iC)

SEND >> 1b 5b 3c 30 63
RECV << 1b 5b 3c 30 3b 32 3b 33 3b 37 63
\x1b[<0;2;3;7c

The CTerm Device Attributes, 3 - Pixel operations supported
(sixel and PPM graphics). I didn't expect it here.

SyncTERM X11: (syncterm -iX)

SEND >> 1b 5b 3c 30 63
RECV << 1b 5b 3c 30 3b 31 3b 32 3b 33 3b 34 3b 35 3b 36 3b 37 63 \x1b[<0;1;2;3;4;5;6;7c

I definitely would expect it here.

I didn't expect it to say it supported it, when
it didn't (or more specifically couldn't).

I agree.

Did I find a bug?

Ok, that's what I've seen used. I wasn't sure if there was a better way
to detect sixel support then the CTDA query.
