screenshot from imageviewer (directly) - as hack

[foldh7]

I have an idea/feature request that could be possible with a jailbroken kindle and would be useful (for me at least):
The possibility to take a screenshot (alt+shift+G) and somehow view the saved image from the kindle.
This is possible by plugging in the kindle over usb and copying the saved *.gif image from the "documents" folder to a "pictures\screenshots" folder...but I would like to achieve this WITHOUT having to connect the kindle to a PC.

Use case:
Railroad time table lookup over the browser. Store the result (as Screenshot) and be able to load it later - without 3G/WiFi or USB/PC connection.

Approach:
No idea ;-) Perhaps even a symlink from documents folder to pictures\screenshots would already do the job? I tried set this up: But creating symlinks is not allowed / possible (when attached over USB as fat filesystem). And microsoft ".lnk" does not work (as expected).

Perhaps one of the jailbreak experts could advise if / how this could be done - or would even be so kind to create a patch just for me...

Welcome to MobileRead, foldh7.

Someone should step in soon with suggestion.....

A quick script to dump the fb to a new file in the pictures folder on ALT+G via the hotkeys hack?

[foldh7]

Hello NiLuJe,

Thanks for your suggestion so fast: Didn't know about the hotkeys hack - does it already work for k3?

I would surely have to look up how to dump a framebuffer (and generate a png out of it...) - your proposal sounds slightly more complicated than I had hoped ;-) but good to know that it should be doable.

Same request - different subforum: https://www.mobileread.com/forums/sho...d.php?t=101200

fbgrab, or something based on the fbgrab code should do the job. QtE for Kindle uses something similar, AFAIK.

EDIT: Or not. fbgrab doesn't seem to support low bitdepth framebuffers.

It might not even be needed, we may have access to a way to get a ready to use fb dump in a more common image format, but I've never looked into this, so I'm not sure about that .

@NiLuJe: Is it possible gain write access to "/opt/amazon/ebook/config/framework.fiona.conf" (usbNetwork/telnet works fine, but not with write permission to this config file)?

I would like to set
PICTURE_DIR_INTERNAL:
from
/mnt/us/pictures
to
/mnt/us
--> this should list the "documents" [=default screenshot] directory as selectable directory from the image viewer...or I hope so ;-)

[NiLuJe]

Fiona is the K2 (Codename: Fiona, Platform: Mario), so that config's not used on a K3 (Codename: Shasta, Platform: Luigi).

But to anwser your question anyway, read the nice MOTD shown on an SSH login .

[foldh7]

ssh root@10.0.0.2 works fine

[foldh7]

Oh and framework.luigi.conf does not have similar settings anyway...so I give up for now: The idea is probably not worth much time (and the risk to break the device...) - but many thanks for your help!

You could symlink pictures to .. if you want to do it that way.

[foldh7]

I had already tried symlinks (several combinations could probably achieve the goal) if the filesystem type would support links...but both "docments" and "pictures" reside in the FAT part (/mnt/us/) of the storage.

So I think the only "simple" approach would be to reconfigure either
a) the picuture-viewer application (consider the documents parent as pictures-root to find screenshots)
or
b) the screenshot tool (placing screenshots in /mnt/us/pictures/shoots/ instead of in /mnt/us/ for the picture-viewer to see them).

[foldh7]

Finally solved my request via launchpad...so trivial ;-)

1.) Create the empty folder "pictures/screenshots"
2.) Add to launchpad.ini: Z = !cp /mnt/us/documents/*.gif /mnt/us/pictures/screenshots

Now you can:
* Take a Screenshot via alt + shift + G
* Press SHIFT,Z
* View the new Screenshot (and any older/other gifs from the documents folder) via the picture-viewer application

From time to time cleanup the gifs (or install a "rm *.gif" launch).

Hi foldh7 - oldish thread i know....
Thanks for the work round.
This would be useful to me but I can't seem to get the script to work. I made an .ini file like the one you did above and put it in the 'Launchpad' folder. I.e.

[Actions] ##
Z = !cp /mnt/us/documents/*.gif/mnt/us/Pictures/Screenshots

and created Pictures/Screenshots in the root directory.
'Shift,Z' just fails after taking a screenshot with Alt+Shift+G. (I did S,S,Space to load the new command).
I have other folders in 'Pictures'. Imageviewer works OK with these other images.
When I looked at launchpad.ini all I could see were a lot of instructions etc nowhere really to put a command hence I made a separate .ini file and tried that. I am a novice tho'!

SOLVED: I'm a dolt! Missed the space after *.gif - now works a treat as a separate .ini script. Have to remember to press alt + Z to make it visible in the Home pages.
Thanks - great for maps.
