kandi X-RAY | paperd Summary
An epaper display server. So you have your epaper display sucessfully connected to your Raspberry Pi. Now what do do with it?. paperd will make it easy to push content to your epaper display by letting you define areas on the display and individually update those areas using a restful web api. In the configuration file those areas are defined with their position on the display and their size. Furthermore it lets you set parameters like how to handle box overflow or font sizes. An area can currently be of type "image" or "text". If you push an image (anything supported by PIL) to an area it will replace the contents of that area. Likewise, text will be written to a text area in the defined font, size and alignment. paperd makes use of the partial update feature of some of the epaper displays available and can currently only work with those. Since epaper displays are notoriously slow, you can use a tk based realtime preview window on your development system. All testing is currently done on a Raspberry Pi Zero W and a Waveshare 2.9" epaper, using Raspbian stretch.

You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
