Random logo feature

[Lykke]

I see that under "Power-off logo" (in Settings→Personalize) there is a feature called "random logo". The Pocketbook manual for TL3 says to place any image in the folder system/logos. I tried placing some covers in jpeg and bmp in that folder and in the subfolder called offlogo, to no effect. Has anyone gotten this feature to work?

The folder name seems wrong. From a look into ebrmain it should be either:
/system/logo/offlogo
/system/logo/bootlogo
or
/logo/offlogo
/logo/bootlogo
not sure myself, since I don't use it.

I'd like to make my own power off logo screen. But have no idea where to add the images


Just so I can add a personalized message like my contact info if my pocketbook is ever stolen/lost and someone can find a way to contact mel

You could add your image into "Photos" folder for instance. Doesn't matter.

Open the Gallery app → open the image → menu button → "Power off logo"

yes, I did try that and it works - but I cannot have a random choice between multiple images: it only uses the last one you set

ok, I solved it for my inkpadX, obtaining a result even better than the one I had on my old Kindle DX:

1) I saved around 100 images of my favorite authors, in grayscale

2) using ImageMagick, I converted them to 16 colors, bmp, resized to fit:

mogrify -resize 1404x1872 -background white -gravity center -extent 1404x1872 -format bmp -colors 16  *

(NB this is the ImageMagicv6 syntax; for v7 I believe it is slightly different)

3) copy the resulting images to /system/logo/offlogo

4) set personalize/power-off logo to random

I hope it's okay to reply to a two-year old thread, but this is still the primary Google hit when trying to figure out the Random Logo feature for the PocketBook, and it's not covered in the manual at all. I thought I'd add my experience in 2022 so others who find this on Google can save the couple hours it took me.

I have an InkPad 3 Pro. I made the mistake of trying to convert and save the images myself in Photoshop CS6, but even after multiple attempts to save with the right bit depth, colors, and resolution, they just wouldn't work. The device would see the images (they appeared in the Gallery app, and also in the list of options for Boot Logo), but couldn't display them. They were blank.

I should have just followed alexxxm's instructions verbatim above, and I'd suggest anyone else coming across this thread to do the same first. I downloaded and installed ImageMagic v7 on Windows 10, and placed the images I wanted to use (saved as Grayscale in Photoshop, as jpg, in the 4x3 aspect ratio) in a folder with nothing else. I ran cmd.exe as Administrator and navigated to the folder with the images, then used the command below. Like alexxxm mentioned, the syntax is SLIGHTLY different, but only barely! You just have to add "magick" to the beginning. So, the below should work:

magick mogrify -resize 1404x1872 -background white -gravity center -extent 1404x1872 -format bmp -colors 16 *

It will convert every image in the folder, and save BMP versions of all of them to the same folder. Add those BMP files to your device, and it will work! If you set it to random logo, it will cycle through them.

And I can confirm that for the InkPad 3 Pro, the folder you put the images in is the same: /system/logo/offlogo

But, even if you have "show hidden files" turned on, you might not be able to see the system folder when you navigate to the Inkpad 3 in Windows Explorer. It is hidden. What you can do is click the address bar and manually add "\system" then press enter (for example, if the PocketBook is set as the E drive, it should read "E:\system"). Then you will be in the folder.

Hope this helps someone!

P.S. Don't try to run the legacy ImageMagick v6. At least for me on my set-up, it threw multiple errors that v7 did not relating to support for image formats.

I wrote a batch script to simplify the ImageMagick conversion. Here's the code in case anyone finds it useful:

@ECHO OFF
TITLE Magick Bulk Convert

Setlocal EnableDelayedExpansion

SET /a i=0
SET /a j=0

::Sets working directory and creates output directory
%~d1
CD "%~p1"
IF NOT EXIST converted MD converted

::count images
FOR %%a in (*.png,*.jpg,*.jpeg,*.gif,*.bmp,*.webp) DO SET /a i+=1

::perfoms convert and calculates percentage done
FOR %%a in (*.png,*.jpg,*.jpeg,*.gif,*.bmp,*.webp) DO (
	magick convert %%a -gravity center -crop 3:4 -adaptive-resize 1072x1448^^! -colorspace gray -colors 16 converted\%%~na.bmp
	SET /a j+=1
	SET /a done=!j!*100/%i%
	CLS
	ECHO.
	ECHO Converting Images - !done!%%
	)
CLS
ECHO.
ECHO Process complete!
ECHO.
PAUSE

Obviously you need to have ImageMagick installed.

Save the text above into notepad, then rename from .txt to .bat

Place the batch script in a folder with the images you want converted, running it will convert images (bmp, gif. jpg, png, webp) to a grayscale 4-bit bmp image. It will also center-crop to a portrait 3:4 aspect ratio, before setting the final resolution (currently set for a HD3, but just edit the code to the resolution for your own device).

The batch script creates a folder called "converted" (in the directory the batch file is run from) and outputs to that folder. The batch file displays a percentage completion whilst running.

Another useful bit of code for anyone interested...

You can send bmp logos/wallpapers to your device by "Send to Pocketbook" emails like you would with ebook files.

Once synced over WIFI, I run a script/application from my device to automatically move the bmp images to the correct directory.

#!/bin/sh

SendToPb="/mnt/ext1/SendToPb"
offlogo="/mnt/ext1/system/logo/offlogo"

find ${SendToPb} -name \*.bmp -exec mv {} ${offlogo} \;

I used Notepad++ to create the script above, I don't think basic Notepad will work.

In Notepad++ create a new document, then go to EDIT>EOL CONVERSION and set the value to "UNIX (LF)"

Paste the code above into Notepad++ and save/close.

Rename from .txt to .app and copy the file to you Pocketbook in the "applications" folder.

To run the script from your device just go to Applications>User's on your device and click on it. There isn't any output, but it should have moved any bmp images synced via "Send to Pocketbook" to the correct directory.
