From b585e87b454917f0424541a34c0b41b1fe83f694 Mon Sep 17 00:00:00 2001 From: Dan Everton Date: Thu, 9 Feb 2006 21:49:28 +0000 Subject: Refactor SDL sim source so drawing routines are written once. Split bitmap, remote, and charcell LCD in to their own files. Add zoom support, use --zoom factor (e.g. --zoom 2 for two times zoom) to use it. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@8645 a1c6a512-1295-4272-9138-f99709370657 --- uisimulator/sdl/lcd-remote.c | 57 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 57 insertions(+) create mode 100644 uisimulator/sdl/lcd-remote.c (limited to 'uisimulator/sdl/lcd-remote.c') diff --git a/uisimulator/sdl/lcd-remote.c b/uisimulator/sdl/lcd-remote.c new file mode 100644 index 0000000000..4d592e67f5 --- /dev/null +++ b/uisimulator/sdl/lcd-remote.c @@ -0,0 +1,57 @@ +/*************************************************************************** + * __________ __ ___. + * Open \______ \ ____ ____ | | _\_ |__ _______ ___ + * Source | _// _ \_/ ___\| |/ /| __ \ / _ \ \/ / + * Jukebox | | ( <_> ) \___| < | \_\ ( <_> > < < + * Firmware |____|_ /\____/ \___ >__|_ \|___ /\____/__/\_ \ + * \/ \/ \/ \/ \/ + * $Id$ + * + * Copyright (C) 2006 Dan Everton + * + * All files in this archive are subject to the GNU General Public License. + * See the file COPYING in the source tree root for full license agreement. + * + * This software is distributed on an "AS IS" basis, WITHOUT WARRANTY OF ANY + * KIND, either express or implied. + * + ****************************************************************************/ + +#include "uisdl.h" +#include "lcd-sdl.h" +#include "lcd-remote.h" + +SDL_Surface *remote_surface; + +SDL_Color remote_color_zero = {UI_REMOTE_BGCOLORLIGHT, 0}; +SDL_Color remote_color_max = {0, 0, 0, 0}; + +extern unsigned char lcd_remote_framebuffer[LCD_REMOTE_HEIGHT/8][LCD_REMOTE_WIDTH]; + +static inline Uint32 get_lcd_remote_pixel(int x, int y) { + return ((lcd_remote_framebuffer[y/8][x] >> (y & 7)) & 1); +} + +void lcd_remote_update (void) +{ + lcd_remote_update_rect(0, 0, LCD_REMOTE_WIDTH, LCD_REMOTE_HEIGHT); +} + +void lcd_remote_update_rect(int x_start, int y_start, int width, int height) +{ + sdl_update_rect(remote_surface, x_start, y_start, width, height, + LCD_REMOTE_WIDTH, LCD_REMOTE_HEIGHT, background ?
