# Cover image
|
||||
|
||||
Saves the cover image of the current book in a file
|
||||
|
||||
## Introduction
|
||||
|
||||
This plugin works as a workaround to solve the lack of support for screensaver in android e-ink devices. While it can be useful in other brands it was tested on **Tolinos** only.
|
||||
|
||||
When you have a book opened, you can find the plugin in the menu `Gear->Screen->Save cover image`
|
||||
|
||||
There you can
|
||||
1. enter the filename to save the cover image.
|
||||
2. enable the creation of the file on every opening of a book.
|
||||
3. exclude saving certain books covers.
|
||||
4. enter the filename of a fallback image.
|
||||
5. turn the fallback on, if a book is closed or KOReader is quit.
|
||||
|
||||
## Sample usage on Tolinos
|
||||
Tolinos can use a file to show a user supplied **suspend** image. So, if you set the cover image filename to that suspend image you can have your books cover as screensaver.
|
||||
|
||||
The name of the suspend image is something like `suspend.jpg` or `suspend_others.jpg`, depending on your firmware and hardware:
|
||||
|
||||
`suspend_others.jpg` on an Epos 2 with FW 14.0.0 and 14.0.1
|
||||
|
||||
`suspend_others.jpg` on a Vision 4HD with FW 13.2.1
|
||||
|
||||
`suspend.jpg` on an Epos 1 with FW 13.2.1 (reported by rola25)
|
||||
|
||||
`suspend.jpg` on a Vision 4HD FW < 11.2.2
|
||||
|
||||
Before you play with the `Save cover image` in KOReader you should check the functionality of the suspend image:
|
||||
1. Connect your Tolino with your computer.
|
||||
2. Mount and open you Tolino on your computer. You should see at least the folders `Books` and `koreader`.
|
||||
3. Copy a JPG image to that folder and rename it.
|
||||
4. Unplug you Tolino.
|
||||
5. Put your Tolino to sleep.
|
||||
6. If you see your image, you know the right suspend image name, if not go to 1.
|
||||
|
||||
(If you don't find a correct filename, you can try to find a filename on `/storage/sdcard1` with `logcat`, when you put your Tolino to sleep.)
|
||||
|
||||
After you have found out the correct name for your suspend image you can enter it in `Set system screensaver image` with the correct path: On my Epos2 the correct name would be `/sdcard/suspend_others.jpg`.
|
||||
|
||||
You can also use a user supplied fallback image on `/sdcard`.
|
||||
|
||||
**NOTE1:** Root is **not** needed.
|
||||
|
||||
**NOTE2:** The image is only shown, when the Tolino **is not connected per USB**.
