Version 0.4.2

This release updates the Waveshare driver library location back to the Official Waveshare repository. Listing changes for both 0.4.2 and 0.4.1 as there was no release made for 0.4.1, although there is a tag for it.

Version 0.4.2

Added

• support for Waveshare 7.3in E display - thanks @antoinecellerier

Changed

• replaced importlib.resources with importlib_resources per the migration information
• Waveshare libraries now loaded from official repo again.

Fixed

• Waveshare 7.3 inch was loading the wrong driver - thanks @reinharty
• Waveshare 1.54in V2 had wrong init() method - thanks @W11T
• fixed GitHub actions Pytests not working

Version 0.4.1 (not released)

Added

• --list argument for the omni-epd-test utility. This will list all valid display options and exit.
• Added PiArtFrame to projects list

Changed

• added development mode install instructions to README

Fixed

• waveshare 1in displays had wrong device name in README - thanks @rpdom
• palette filter processing was not working with modes other than black/white - thanks @fardage for the issue

Version 0.4.0

Version 0.4.0

This release adds support for Raspberry Pi OS 12 (Bookworm) as well as Python 3.11 for all implemented displays. This release is backwards compatible with Raspberry Pi OS 11 (Bullseye) so it can be install directly over the top of Version 0.3.5.

Worth noting is that the Waveshare drivers are being pulled from a forked repository as the official Waveshare repo still does not have support for Bookworm. Once support is added omni-epd will switch back to the official repo.

Added

• support for Raspberry Pi OS 12 (Bookworm) and Python 3.11 through some dependency fixes
• information regarding Python virtual environment usage
• disclaimer on status of official Waveshare repo support with Bookworm

Changed

• updated IT8951 repo link to build from source with RPI dependencies
• Waveshare drivers now loaded from forked repo to fix Bookworm Rpi detection
• setup.cfg information merged into pyproject.toml

Version 0.3.5

The Python version in this release is bookended between 3.7 and 3.10. This is due to some changes in Raspberry Pi OS 12 (Bookworm), which ships with Python 3.11. Many upstream libraries, like Waveshare, will not run on this platform yet. Changes to get these libraries working may make upcoming releases not backwards compatible once Python 3.11 support is added. Since Waveshare doesn't using versioning on their libs this release will provide a cutoff for what versions of this library work depending on the Python version you have. If future updates are backwards compatible these restrictions will be removed in future versions of omni-epd.

Changed

• changed valid Python versions from 3.7 < 3.11. Issues currently on 3.11 installs running on Raspberry Pi OS 12 (Bookworm)
• pinned Waveshare repo to 4822c07. This is known to work with Python 3.7 < 3.10.
• pinned IT8951 repo to 6721516. This is known to work with Python 3.7 < 3.10.

Fixed

• Updated Waveshare GitHub URL to https://github.com/waveshareteam/e-Paper/ in README and documentation
• Fixed Waveshare 1.02in as the display() method has changed

Version 0.3.4

Added

• palette_filter advanced option now supports color names or hex values in addition to RGB colors. Thanks @missionfloyd
• IT8951 devices now support gray16 mode for grayscale
• Waveshare 10.3 IT8951 device marked as tested. Thanks @simonjowett

From 0.3.3 (no release)

Added

• added link to pycasso in the README. Thanks @jezs00
• new displays, Waveshare 7.3in 7 Color - thanks @evelyndooley, Waveshare 2.13in V3

Version 0.3.2

Version 0.3.2

Changed

• updated Pillow min version to 9.1+
• code cleanup for proper style standards - thanks @missionfloyd

Added

• added new 4 color waveshare displays (epd1in64g, epd2in36g, epd3in0g, epd4in37g, epd7in3g). Thanks @missionfloyd

Version 0.3.1

Version 0.3.1

Added

• omni_epd.mock can now set both the width and height values within the .ini file. Thanks @missionfloyd

Fixed

• omni_epd.mock device now returns a palette filter when using the color mode. Previously this returned only b/w and resulted in image processing enhancements resulting in a black and white only image, even when color was selected. Hardcoded palette based on web safe colors.

• Waveshare device epd2in13_V2 should use the alternate clear method which requires a color parameter. Thanks @ThatIsAPseudo for pointing this out

Changed

• dithering is now done with didder - this is a massive improvement both in scope and speed to hitherdither. Thanks @missionfloyd

Removed

• removed hitherdither as a dependency

Version 0.3.0

Added

• added force_palette argument to the virtualepd._filter() function. Will force palette based conversion if wanted, default is False
• added additional tested displays per #63 comments
• new unit tests to make sure image processing components run without error
• support for inky.auto as a valid EPD device. This will auto detect Inky devices and load the correct driver. Thanks @donbing
• support for IT8951 devices, such as the WaveShare 6in display

Fixed

• calls to Image.quantize require an RGB or L mode Image object, convert any loaded image before applying new palettes
• when filling palette too many colors were being set (< 256), wrong length variable was being used
• fixed regression where Inky bw mode was causing colors to be inverted
• universal fix for Waveshare Tri-color displays as original fixes broke some displays - thanks @aaron8684

Changed

• make sure Pillow and Inky packages are known working versions or above - thanks @donbing
• bw standardized as the consistent naming for the default black/white device mode. black will throw a warning, affects Inky devices - thanks @missionfloyd

Version 0.2.6

0.2.6

Added

• added version identifier for Waveshare devices so that V2 and V3 boards can be identified from the others

Fixed

• fixed typos in 5.65in Waveshare implementation - thanks @aaronr8684
• fixed issues with BW display on 7.5 tri-color screens - thanks @aaronr8684

Removed
