Current page as boot/start logo in Pocketbook

[longu]

Hi guys
I'm using Pocketbook Verse Pro with KOReader as default app. I managed to configure a book cover as a boot up/start logo thanks to the guides found here. Is it possible to configure last/current page from KOReader as the logo? This would greatly speed up reading process for my PB.
Best regards.

I had the idea to make a plugin for this. However, I got stuck already at the preparatory stage. I couldn't figure out what mechanism PocketBook uses to save the current page. The files on the reader don't contain any screenshots of the page or anything similar. Maybe someone smarter than me can figure it out.

There's already a plugin that saves the cover image to a file on PocketBook if you enable it in Screen → Cover image. Maybe it already does what you want?

I'm aware about the plugin and as I already mentioned I'm using it for the book covers. The problem I have with Pocketbook it drains battery (5%) when not used. The solution for that issue is to turn off the device, but it takes 22s before I can start reading (boot up), so I wanted to shorten the time by displaying the page instead a cover during startup. It's possible when using built in reader, but I'm using KOReader.

If it already works for the cover that's surely a good starting point for reuerendo.

I did it. It was really simple. Literally two lines of code. You can try my fork of the pocketbooksync.koplugin. You also need to replace the file inkview_h.lua in the koreader/ffi/ folder (one of the lines has been added to this file. It won't work without it.)

That's a great news! How do I install it?
Just unzip the attached file to my pocketbook and that's all?
Best regards

The easiest way is to copy the "koreader" folder from the archive to the "applications" folder on your device and agree to replace the files.
The page will be displayed on loading if the KOreader was open when the device was turned off. And, of course, you need to enable the display of the last page in the device settings

I did as you wrote and now my KOReader crashes when trying to open a book.

Not sure why the image is not displayed

Apparently there's some difference between our devices. I'm using an InkPad 4. Delete the pocketbooksync.koplugin folder from the koreader/plugins folder and everything will return to normal. Later I'll check what can be done with this.

Installed this version, deleted pocketbooksync.koplugin folder, but it still crashes. Do you want me to send the photo of the error or any logs? Do I need any plugin to have installed in order this tweak to work?

After some research, it turned out that the problem was in an outdated version of KOreader.

So the plugin works.

I also created a patch that disables the info message from being displayed when opening a book.

Fork of pocketbooksync.koplugin, inkview_h.lua file replacement and patch - in the archive.

Perhaps someone will find this information useful for development, the PageSnapshot() function from the Pocketbook SDK is responsible for saving a screenshot of the last opened page.

Thanks to longu for the tests

I confirm it's working flawlessly, once again thanks @reuerendo!
