From f3f744d36a60431a6845d2b7e3ce17e64ee2e4f5 Mon Sep 17 00:00:00 2001 From: truelight Date: Tue, 12 Jun 2007 20:24:12 +0000 Subject: (svn r10121) -Codechange: split renderer from rest of code; no longer any code directly accesses the video-buffer -Add: added NULL blitter and renderer, which are always used for -vnull -Add: dedicated driver doesn't blit nor render by default. Can be overruled by user. (-D -b 8bpp-optimized) -Remove: removed CTRL+D from win32, which is incompatible with above -Add: extended screenshot support for PNG and BMP -Codechange: remove all hardcoded 8bpp references and replace them with more dynamic ones -Codechange: minor stuff in blitters --- src/video/win32_v.cpp | 101 +++++++++----------------------------------------- 1 file changed, 17 insertions(+), 84 deletions(-) (limited to 'src/video/win32_v.cpp') diff --git a/src/video/win32_v.cpp b/src/video/win32_v.cpp index cee533c7c..9e14290d3 100644 --- a/src/video/win32_v.cpp +++ b/src/video/win32_v.cpp @@ -9,6 +9,7 @@ #include "../variables.h" #include "../win32.h" #include "../window.h" +#include "../blitter/blitter.hpp" #include "win32_v.h" #include #include @@ -16,22 +17,18 @@ static struct { HWND main_wnd; HBITMAP dib_sect; - Pixel *bitmap_bits; - Pixel *buffer_bits; - Pixel *alloced_bits; + void *buffer_bits; HPALETTE gdi_palette; int width; int height; int width_org; int height_org; bool fullscreen; - bool double_size; bool has_focus; bool running; } _wnd; bool _force_full_redraw; -bool _double_size; bool _window_maximize; uint _display_hz; uint _fullscreen_bpp; @@ -63,6 +60,10 @@ static void MakePalette() static void UpdatePalette(HDC dc, uint start, uint count) { + /* We can only update the palette in 8bpp for now */ + /* TODO -- We need support for other bpps too! */ + if (BlitterFactoryBase::GetCurrentBlitter()->GetScreenDepth() != 8) return; + RGBQUAD rgb[256]; uint i; @@ -136,11 +137,6 @@ static bool AllocateDibSection(int w, int h); static void ClientSizeChanged(int w, int h) { - if (_wnd.double_size) { - w /= 2; - h /= 2; - } - // allocate new dib section of the new size if (AllocateDibSection(w, h)) { // mark all palette colors dirty @@ -319,11 +315,6 @@ static LRESULT CALLBACK WndProcGdi(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lP DrawMouseCursor(); } - if (_wnd.double_size) { - x /= 2; - y /= 2; - } - if (_cursor.fix_at) { int dx = x - _cursor.pos.x; int dy = y - _cursor.pos.y; @@ -334,10 +325,6 @@ static LRESULT CALLBACK WndProcGdi(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lP pt.x = _cursor.pos.x; pt.y = _cursor.pos.y; - if (_wnd.double_size) { - pt.x *= 2; - pt.y *= 2; - } ClientToScreen(hwnd, &pt); SetCursorPos(pt.x, pt.y); } @@ -400,13 +387,6 @@ static LRESULT CALLBACK WndProcGdi(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lP * WM_KEYDOWN only handles CTRL+ commands and special keys like VK_LEFT, etc. */ if (keycode == 0 || (keycode > WKC_PAUSE && GB(keycode, 13, 4) == 0)) return 0; - if (keycode == ('D' | WKC_CTRL) && !_wnd.fullscreen) { - _double_size ^= 1; - _wnd.double_size = _double_size; - ClientSizeChanged(_wnd.width, _wnd.height); - MarkWholeScreenDirty(); - } - HandleKeypress(0 | (keycode << 16)); return 0; } @@ -455,16 +435,8 @@ static LRESULT CALLBACK WndProcGdi(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lP w = r->right - r->left - (r2.right - r2.left); h = r->bottom - r->top - (r2.bottom - r2.top); - if (_wnd.double_size) { - w /= 2; - h /= 2; - } w = clamp(w, 64, MAX_SCREEN_WIDTH); h = clamp(h, 64, MAX_SCREEN_HEIGHT); - if (_wnd.double_size) { - w *= 2; - h *= 2; - } SetRect(&r2, 0, 0, w, h); AdjustWindowRect(&r2, GetWindowLong(hwnd, GWL_STYLE), FALSE); @@ -567,8 +539,6 @@ static void MakeWindow(bool full_screen) { _fullscreen = full_screen; - _wnd.double_size = _double_size && !full_screen; - // recreate window?
