Can anyone get seejpeg & svgalib to work? An alternative non-X image viewer?

My suggestion is a non-X image viewer, it just needs tweaking to get it to build with imlib2 support on 14.2 (otherwise, it will only display bitmap images). I provided that option if you want to try and play with it and see if you can get it to compile. It worked fine on 14.1 using ssh, so it's just a matter of finding what needs to be done to fix it on 14.2.

If you don't want to take the time, I totally understand, but it is a non-X image viewer that's included in Slackware, it's just currently built without imlib2 support (which is required to view jpeg and png images).

seejpeg and svgalib are still Slackware packages: they may be effectively dead but they live in Slackware's distribution. If no one can make them work perhaps they should be removed.

Oh yeah here they are,
https://slackware.pkgs.org/14.2/slac..._64-1.txz.html

Code:

$ ls /var/log/packages | grep seejpeg
seejpeg-1.10-x86_64-1

but why you telling me? I am just a user, not the Author

what a mean they don't work?

inside of windowmaker

Code:

$ seejpeg -g /media/data/wallpaper/Panaroma/dbcb4cac-67d5-4012-bee1-8e06921bfe03_5.jpg
 
Are you running this program as root or suid-root?

so I

Code:

$ sudo seejpeg -g /media/data/wallpaper/Panaroma/dbcb4cac-67d5-4012-bee1-8e06921bfe03_5.jpg

then it kicked me out of WMaker, and left me a message.

Code:

svgalib : rage driver must be used but not found.

then I ended up having to shut down with the power button.

Thanks, it works well.

Hey Mr. RandomTroll, did you ever get this working? A post on another thread made me try it, but I seem to be butting my head... A quick Google search lead me to your post. Just wondering if you've had any joy?

Using links with the fb driver works quite well... but I'm keener to get seejpeg/svgalib working if possible.

I think the day has passed that anyone using up-to-date video software can use svgalib. I use fbida, which I have to build myself as Slackware has no package for it.

There's a w3m web browser which can draw images in both tty and terminal window. Many people install it in order to preview graphical files in terminal file managers like ranger and vifm. There is also Überzug, a Python package which allows preview in terminal windows, but my guess is that it won't work in teletype, as it requires X. W3mimgdisplay is a small program that ships with w3m and its purpose is to draw images for w3m. You could install w3m and wrap w3mimgdisplay in a script. I have started learning bash last week, so I wrote this as an exercise, so that you (or anyone else) can try it as quickly as possible, but keep in mind that I am a supernewbie, so please proofread it, adjust it to fit your need and so on, before you run it.

Code:

#!/bin/env bash

W3MIMGDISPLAY_PATH="${W3MIMGDISPLAY_PATH:-/usr/libexec/w3m/w3mimgdisplay}"
# size of font in pixels in
# terminal emulator
fontWidth=8
fontHeight=14
# and tty
linuxWidth=9
linuxHeight=16

[[ $1 == '' ]] && { printf '%s\n' 'usage: img2xterm [ARG]'; exit 1; }
[[ -x $W3MIMGDISPLAY_PATH ]] || { printf '%s\n%s\n' "w3mimgdisplay not found here:" "$W3MIMGDISPLAY_PATH"; exit 1; }

prepare() {
    case $TERM in
        xterm)
            theFontWidth="$fontWidth"
            theFontHeight="$fontHeight"
            ;;
        linux)
            theFontWidth="$linuxWidth"
            theFontHeight="$linuxHeight"
            ;;
        # Your terminal goes here.
        *)
            theFontWidth="$fontWidth"
            theFontHeight="$fontHeight"
            ;;
    esac
}

draw() {
    local width height lines columns
    read -r width height <<< "$("$W3MIMGDISPLAY_PATH" <<< "$(printf '5;%s' "$1")")"
    read -r lines columns <<< "$(stty size)"
    local maxWidth=$((theFontWidth * columns))
    local maxHeight=$((theFontHeight * $((lines - 1))))
    if [[ $width -gt $maxWidth ]]; then
        height=$((height * maxWidth / width))
        width="$maxWidth"
    fi
    if [[ $height -gt $maxHeight ]]; then
        width=$((width * maxHeight / height))
        height="$maxHeight"
    fi
    clear
    tput cup $((height / fontHeight + 1)) 0
    "$W3MIMGDISPLAY_PATH" <<< "$(printf '0;1;0;0;%s;%s;;;;;%s\n4;\n3;' "$width" "$height" "$1")"
}

prepare
draw "$1"

Here you can find viewer written for vifm that uses Überzug as previewer, but it could probably be rewritten to use w3m. You could read pdf files from tty. Convert from ImageMagick works faster for pdf, but at cost of quality loss. Macros that vifm sends to Überzug (%px, %py, %pw, %ph and %c) go here:

Code:

# px, py - coordinates of top left corner of image
# pw, ph - width and height of image
# c - file to draw

w3mString="0;1;$px;$py;$pw;$ph;;;;;$c\n4;\n3;"
echo -e "$w3mString" | /path/to/w3mimgdisplay

I have been using w3mimgdisplay in ranger and vifm for ages. It works fine in xterm, but ranger has some issues after v. 1.8.1, at least for me, so I moved to vifm and was forced to learn bash

I believe that the best non-X image viewer is Gwenview running in Wayland/Plasma5. This way it uses, of course, Wayland instead of X11.

Is Wayland graphical?

Yeah, this Wayland is so graphical that the entire Plasma5 desktop runs on it, not only Gwenview...

I wanted non-graphical. I'm so behindhand I didn't know there was an alternative to X. I prefer text mode.

Booting without any framebuffer drivers loaded (including nvidia blob) and forcing chipset VGA in /etc/vga/libvga.config should be enough to get it working :-)

Is Gthumb in Slackware? That's a very good image viewer!

Only for X.

It is not included in Slackware.
