Picture home screen

Replaces the home screen while it is on: a picture from your card behind the pages of widgets and tools you arrange. Switch it off in the plugin manager and the built-in home screen is back. The picture can fill the screen, show whole, stretch, keep its size or tile, with position, zoom, brightness and contrast controls. You can also lighten the picture so that widgets stay easy to read. It is prepared once for each picture and screen size, then drawn from the card row by row. The status bar can be on, off or automatic (a button press shows it for a few seconds, and that press does nothing else), at the top or the bottom, full width or a small pill at the left, middle or right, on a light, inverted, light grey or dark grey plate, or on the picture itself. The row that names the buttons can be on, off or automatic as well.

How it works

Picture home screen replaces the home screen while it is on: your own picture behind the widgets, and the pages of widgets and tools you arrange. Switch it off in the plugin manager and the built-in home screen is back, with its own pages.

Put pictures (JPEG, PNG or GIF) in a folder on the card (wallpapers by default), then choose one in Settings, Customise, Picture home screen. Fit says how it fills the screen (fill, whole picture, stretch, original size, tile), Position which part stays, Zoom how large, and Lighten picture how pale: a paler picture makes the widgets easier to read. The picture is prepared once for each screen size, which takes a moment.

Widgets sit on plates over the picture. Arrange the page as on the built-in home screen: the pencil below the page, or Edit home screen in the menu.

The status bar (time, Wi-Fi, battery, or what you choose) can be on, off or automatic, at the top or the bottom, full width or a small pill at the left, middle or right, on a light, dark or grey plate or on the picture itself. The row naming the buttons (on the X4) can be on, off or automatic too. Automatic means a button press shows them for a few seconds; that press does nothing else.

Picture rendering says how the picture is drawn: Grey levels in every grey the screen has (slower on the X4), Dithered in black and white dots (fast), or Automatic, as the built-in home screen does: grey levels when the screen is drawn, dots after the first change. Where a screen has no grey levels, grey levels fall back to dots.

A plugin with code runs with full access to the reader. It can read everything on it, your passwords and other secrets included, and use the network. A faulty one can crash the reader; a hostile one can damage it for good. Install it only if you trust who made it, as you would a program on a computer.

Works with interface 6 (PaperPaw 0.6 betas).

Builds

It is built for the Xteink X4, Xteink X4 Pro and Xteink X4 Classic, made for PaperPaw 0.6. A build runs on every PaperPaw of the same plugin interface. When a release raises the interface, a reader on that release waits until the author makes a new build.

On an Xteink X4 the code of all plugins you have turned on shares limited room, about 600 KB if PaperPaw came by an update from CrossPoint. If the reader says there is not enough room, a full flash with the flasher leaves about four times as much: see the help there. Few plugins with code fit on my X4

Its code, open to read

The store shows the source of every plugin with code and keeps a copy, and rebuilds each build from that source with the compiler its fingerprint names, to compare. The file served is always the one its author signed.
