From 1f2b1dedccdf21b629c45ece80b4ca32f6653296 Mon Sep 17 00:00:00 2001 From: Nick Brassel Date: Wed, 13 Apr 2022 18:00:18 +1000 Subject: Quantum Painter (#10174) * Install dependencies before executing unit tests. * Split out UTF-8 decoder. * Fixup python formatting rules. * Add documentation for QGF/QFF and the RLE format used. * Add CLI commands for converting images and fonts. * Add stub rules.mk for QP. * Add stream type. * Add base driver and comms interfaces. * Add support for SPI, SPI+D/C comms drivers. * Include when enabled. * Add base support for SPI+D/C+RST panels, as well as concrete implementation of ST7789. * Add support for GC9A01. * Add support for ILI9341. * Add support for ILI9163. * Add support for SSD1351. * Implement qp_setpixel, including pixdata buffer management. * Implement qp_line. * Implement qp_rect. * Implement qp_circle. * Implement qp_ellipse. * Implement palette interpolation. * Allow for streams to work with either flash or RAM. * Image loading. * Font loading. * QGF palette loading. * Progressive decoder of pixel data supporting Raw+RLE, 1-,2-,4-,8-bpp monochrome and palette-based images. * Image drawing. * Animations. * Font rendering. * Check against 256 colours, dump out the loaded palette if debugging enabled. * Fix build. * AVR is not the intended audience. * `qmk format-c` * Generation fix. * First batch of docs. * More docs and examples. * Review comments. * Public API documentation. --- lib/python/qmk/cli/painter/__init__.py | 2 + lib/python/qmk/cli/painter/convert_graphics.py | 86 +++++++++++++++++++++++++ lib/python/qmk/cli/painter/make_font.py | 87 ++++++++++++++++++++++++++ 3 files changed, 175 insertions(+) create mode 100644 lib/python/qmk/cli/painter/__init__.py create mode 100644 lib/python/qmk/cli/painter/convert_graphics.py create mode 100644 lib/python/qmk/cli/painter/make_font.py (limited to 'lib/python/qmk/cli/painter') diff --git a/lib/python/qmk/cli/painter/__init__.py b/lib/python/qmk/cli/painter/__init__.py new file mode 100644 index 0000000000..d1a225346c --- /dev/null +++ b/lib/python/qmk/cli/painter/__init__.py @@ -0,0 +1,2 @@ +from . import convert_graphics +from . import make_font diff --git a/lib/python/qmk/cli/painter/convert_graphics.py b/lib/python/qmk/cli/painter/convert_graphics.py new file mode 100644 index 0000000000..bbc30d26ff --- /dev/null +++ b/lib/python/qmk/cli/painter/convert_graphics.py @@ -0,0 +1,86 @@ +"""This script tests QGF functionality. +""" +import re +import datetime +from io import BytesIO +from qmk.path import normpath +from qmk.painter import render_header, render_source, render_license, render_bytes, valid_formats +from milc import cli +from PIL import Image + + +@cli.argument('-v', '--verbose', arg_only=True, action='store_true', help='Turns on verbose output.') +@cli.argument('-i', '--input', required=True, help='Specify input graphic file.') +@cli.argument('-o', '--output', default='', help='Specify output directory.
