From 9e0f614ce8c8d0685431db29ac5344c6090bfe96 Mon Sep 17 00:00:00 2001 From: scawful Date: Mon, 29 Sep 2025 21:21:49 -0400 Subject: [PATCH] Add BPP format management and optimization features - Introduced BPPFormatManager for handling various bitmap formats (2BPP, 3BPP, 4BPP, 8BPP) with conversion capabilities. - Enhanced AtlasRenderer to support bitmap addition with BPP format optimization and added methods for optimized rendering. - Implemented GraphicsOptimizer for analyzing and optimizing graphics sheets based on BPP formats, including memory and performance considerations. - Developed BppFormatUI for user interface interactions related to BPP format selection and conversion previews. - Integrated BPP format management into the canvas system, allowing for format selection and conversion within the GUI. - Updated CMake configuration to include new source files related to BPP management and optimization. --- src/app/gfx/atlas_renderer.cc | 104 ++++- src/app/gfx/atlas_renderer.h | 26 +- src/app/gfx/bpp_format_manager.cc | 450 ++++++++++++++++++++++ src/app/gfx/bpp_format_manager.h | 243 ++++++++++++ src/app/gfx/gfx.cmake | 2 + src/app/gfx/graphics_optimizer.cc | 458 ++++++++++++++++++++++ src/app/gfx/graphics_optimizer.h | 235 ++++++++++++ src/app/gui/bpp_format_ui.cc | 619 ++++++++++++++++++++++++++++++ src/app/gui/bpp_format_ui.h | 248 ++++++++++++ src/app/gui/canvas.cc | 74 ++++ src/app/gui/canvas.h | 14 + src/app/gui/gui.cmake | 1 + 12 files changed, 2469 insertions(+), 5 deletions(-) create mode 100644 src/app/gfx/bpp_format_manager.cc create mode 100644 src/app/gfx/bpp_format_manager.h create mode 100644 src/app/gfx/graphics_optimizer.cc create mode 100644 src/app/gfx/graphics_optimizer.h create mode 100644 src/app/gui/bpp_format_ui.cc create mode 100644 src/app/gui/bpp_format_ui.h diff --git a/src/app/gfx/atlas_renderer.cc b/src/app/gfx/atlas_renderer.cc index 59449b54..07cdd5a1 100644 --- a/src/app/gfx/atlas_renderer.cc +++ b/src/app/gfx/atlas_renderer.cc @@ -2,6 +2,7 @@ #include #include +#include "app/gfx/bpp_format_manager.h" namespace yaze { namespace gfx { @@ -36,8 +37,9 @@ int AtlasRenderer::AddBitmap(const Bitmap& bitmap) { int atlas_id = next_atlas_id_++;
