# epdlib v0.6

EpdLib provides an interface for creating and displaying scalable layouts that work with most of WaveShare's EPaper displays (EPD). The `Layout` module can also be used for generating layouts for any screen-buffered display that does not require fast updates. 

EpdLib provides classes for interfacing with the screen (`Screen`), building layouts that will work at any resolution (`Layout`), and blocks that are used to assemble layouts (`Block`). EpdLib makes it trivial to build a project that will work on almost any WaveShare display without worrying about the resolution or recoding the display functions.

![5x5 Sample](./docs/weather_5x5.png)

EpdLib supports almost all of WaveShare's EPD screens. See the [Supported Screens](#supported-screens) below.

* 7-Color screens are supported in full color
* HD Screens are supported in 8 bit gray and support partial refresh (~1 second)
* All 2 and 3 color screens are supported in 1 bit (black and white) only

## Changes

See the [ChangeLog](./changes.md) for details

### v0.6

* Add support for 8-Color WaveShare screens to Block, Screen and Layout
* All Blocks and Layouts now support "RGB" content
* Layouts and blocks can now be dynamically updated during runtime
* `Layout.layout` dictionaries must contain key `type` that matches the block type
* Layouts support HTML standard color names and map [RED, ORANGE, YELLOW, GREEN, BLUE, BLACK, WHITE] to proper WaveShare Values

## Dependencies

Python Modules:
* Pillow: System dependencies for Pillow:
    * libopenjp2-7
    * libtiff5
* RPi.GPIO
* spidev: ensure SPI is enabled on the pi
* waveshare-epd (Non IT8951 based panels): see [notes](#notes) below for installation instructions
    * this is for interacting with waveshare epaper displays and is not strictly needed to use the Block and Layout objects.
* IT8951 (IT8951 based panels): see [notes](#notes) below for installation instructions


## Modules:

* [Block](./docs/Block.md) - image and text blocks that can be used to create a layout
* [Layout](./docs/Layout.md) - create layouts from Blocks that will work on nearly any WaveShare screen automagically
* [Screen](./docs/Screen.md) - simple interface for writing to WaveShare EPD devices

Add your enthusiasm to standardize the `epd1in02` screen to [this Pull Request](https://github.com/waveshare/e-Paper/pull/283). 

The `epd3in7` is an oddball that has several issues:

* 'Non-standard, unsupported `EPD.Clear()` function',
* 'AttributeError: module does not support standard `EPD.display()` function

## Notes
