From d1bf7919daf830befd8c2166f3844fcdb56d68fa Mon Sep 17 00:00:00 2001 From: Yuri Kunde Schlesner Date: Sat, 27 May 2017 16:10:25 -0700 Subject: Move framebuffer_layout from Common to Core This removes a dependency inversion between core and common. It's also the proper place for the file since it makes screen layout decisions specific to the 3DS. --- src/common/CMakeLists.txt | 2 - src/common/framebuffer_layout.cpp | 157 -------------------------------------- src/common/framebuffer_layout.h | 55 ------------- 3 files changed, 214 deletions(-) delete mode 100644 src/common/framebuffer_layout.cpp delete mode 100644 src/common/framebuffer_layout.h (limited to 'src/common') diff --git a/src/common/CMakeLists.txt b/src/common/CMakeLists.txt index 6905d2d50..546a14500 100644 --- a/src/common/CMakeLists.txt +++ b/src/common/CMakeLists.txt @@ -27,7 +27,6 @@ configure_file("${CMAKE_CURRENT_SOURCE_DIR}/scm_rev.cpp.in" "${CMAKE_CURRENT_SOU set(SRCS break_points.cpp file_util.cpp - framebuffer_layout.cpp hash.cpp logging/filter.cpp logging/text_formatter.cpp @@ -56,7 +55,6 @@ set(HEADERS common_paths.h common_types.h file_util.h - framebuffer_layout.h hash.h linear_disk_cache.h logging/text_formatter.h diff --git a/src/common/framebuffer_layout.cpp b/src/common/framebuffer_layout.cpp deleted file mode 100644 index a2a0e7dad..000000000 --- a/src/common/framebuffer_layout.cpp +++ /dev/null @@ -1,157 +0,0 @@ -// Copyright 2016 Citra Emulator Project -// Licensed under GPLv2 or any later version -// Refer to the license.txt file included. - -#include - -#include "common/assert.h" -#include "common/framebuffer_layout.h" -#include "core/settings.h" -#include "video_core/video_core.h" - -namespace Layout { - -static const float TOP_SCREEN_ASPECT_RATIO = - static_cast(VideoCore::kScreenTopHeight) / VideoCore::kScreenTopWidth; -static const float BOT_SCREEN_ASPECT_RATIO = - static_cast(VideoCore::kScreenBottomHeight) / VideoCore::kScreenBottomWidth; - -// Finds the largest size subrectangle contained in window area that is confined to the aspect ratio -template -static MathUtil::Rectangle maxRectangle(MathUtil::Rectangle window_area, - float screen_aspect_ratio) { - float scale = std::min(static_cast(window_area.GetWidth()), - window_area.GetHeight() / screen_aspect_ratio); - return MathUtil::Rectangle{0, 0, static_cast(std::round(scale)), - static_cast(std::round(scale * screen_aspect_ratio))}; -} - -FramebufferLayout DefaultFrameLayout(unsigned width, unsigned height, bool swapped) { - ASSERT(width > 0); - ASSERT(height > 0); - - FramebufferLayout res{width, height, true, true, {}, {}}; - // Default layout gives equal screen sizes to the top and bottom screen - MathUtil::Rectangle screen_window_area{0, 0, width, height / 2}; - MathUtil::Rectangle top_screen = - maxRectangle(screen_window_area, TOP_SCREEN_ASPECT_RATIO); - MathUtil::Rectangle bot_screen = - maxRectangle(screen_window_area, BOT_SCREEN_ASPECT_RATIO); - - float window_aspect_ratio = static_cast(height) / width; - // both screens height are taken into account by multiplying by 2 - float emulation_aspect_ratio = TOP_SCREEN_ASPECT_RATIO * 2; - - if (window_aspect_ratio < emulation_aspect_ratio) { - // Apply borders to the left and right sides of the window. - top_screen = - top_screen.TranslateX((screen_window_area.GetWidth() - top_screen.GetWidth()) / 2); - bot_screen = - bot_screen.TranslateX((screen_window_area.GetWidth() - bot_screen.GetWidth()) / 2); - } else { - // Window is narrower than the emulation content => apply borders to the top and bottom - // Recalculate the bottom screen to account for the width difference between top and bottom - screen_window_area = {0, 0, width, top_screen.GetHeight()}; - bot_screen = maxRectangle(screen_window_area, BOT_SCREEN_ASPECT_RATIO); - bot_screen = bot_screen.TranslateX((top_screen.GetWidth() - bot_screen.GetWidth()) / 2); - if (swapped) { - bot_screen = bot_screen.TranslateY(height / 2 - bot_screen.GetHeight()); - } else { - top_screen = top_screen.TranslateY(height / 2 - top_screen.GetHeight()); - } - } - // Move the top screen to the bottom if we are swapped. - res.top_screen = swapped ? top_screen.TranslateY(height / 2) : top_screen; - res.bottom_screen = swapped ? bot_screen : bot_screen.TranslateY(height / 2); - return res; -} - -FramebufferLayout SingleFrameLayout(unsigned width, unsigned height, bool swapped) { - ASSERT(width > 0); - ASSERT(height > 0); - // The drawing code needs at least somewhat valid values for both screens - // so just calculate them both even if the other isn't showing. - FramebufferLayout res{width, height, !swapped, swapped, {}, {}}; - - MathUtil::Rectangle screen_window_area{0, 0, width, height}; - MathUtil::Rectangle top_screen = - maxRectangle(screen_window_area, TOP_SCREEN_ASPECT_RATIO); - MathUtil::Rectangle bot_screen = - maxRectangle(screen_window_area, BOT_SCREEN_ASPECT_RATIO); - - float window_aspect_ratio = static_cast(height) / width; - float emulation_aspect_ratio = (swapped) ?
