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. --- quantum/painter/qp_internal_formats.h | 49 +++++++++++++++++++++++++++++++++++ 1 file changed, 49 insertions(+) create mode 100644 quantum/painter/qp_internal_formats.h (limited to 'quantum/painter/qp_internal_formats.h') diff --git a/quantum/painter/qp_internal_formats.h b/quantum/painter/qp_internal_formats.h new file mode 100644 index 0000000000..a4a86f0345 --- /dev/null +++ b/quantum/painter/qp_internal_formats.h @@ -0,0 +1,49 @@ +// Copyright 2021 Nick Brassel (@tzarc) +// SPDX-License-Identifier: GPL-2.0-or-later + +#pragma once + +#include "qp_internal.h" + +//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// +// Quantum Painter pixel formats + +// Datatype containing a pixel's color.
