Sleep screen image always assumes portrait orientation, even when reading in landscape

[yfede]

• KOReader version: 2024.04
• Device: Kobo Aura (model N514)

Issue

Sleep screen image is always displayed in portrait orientation, even when the book was being read in landscape

If a message string is set, the string as well is displayed in portrait mode, i.e. the base of the string is parallel to the short side of the kobo, not the long one

Steps to reproduce

1. Set reading orientation to landscape
2. Set a sleep screen image that is 1024 px wide by 768 pixels high
3. Put the device to sleep

Expected result:

The image in the sleep screen should fill the whole display, with the long side of the image aligned with the long side of the device, like this (this is how the image is displayed when opened with the viewer):

Actual result:

The image is scaled down, displayed in the center of the screen, with the long side of the image aligned with the short side of the device

Final note:

You may say: "why don't you save your image with a rotation to compensate for the above behavior, so that it is 768 px wide and 1024 px high?"

That may work for solving the problem of the image itself, but the string message would still be displayed conforming to the portrait orientation, while I would like it to appear at the bottom of the image in landscape mode, in order to take advantage of the bigger length of the long side of the device

If it's problematic to obtain/retain the current reading orientation and apply it to the sleep screen, an equally satisfactory solution would be IMHO to add an explicit setting in the recently overhauled "sleep screen" menu, to indicate the intended orientation of the sleep screen

That's the expected behaviour. Sleep message/stats/picture/.., booting KOReader from KFMon, USBnet... All work on the native orientation. That's 0º.

While it might be yet another good feature for somebody I would suggest to implement it as an user patch.

but... if the sleep screen is set to show the reading statistics, then it follows the reading orientation instead (see proof below), so it doesn't seem mandatory to respect the native orientation in the sleep screen after all, or am I missing something?

Reading statistics (I believe) is a screenshot
