From c4eea8f11fa2386cafb20e22fe5451106b5ade52 Mon Sep 17 00:00:00 2001 From: Teruaki Kawashima Date: Thu, 18 Feb 2010 15:10:31 +0000 Subject: FS#10535: bmp viewer plugin. * changed bmp.c so that it loads bitmap larger than LCD correctly. * removed bmp entry form inbuilt_filetypes in filetypes.c so that bmp files will be opened with bmp viewer when selected in browser. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@24754 a1c6a512-1295-4272-9138-f99709370657 --- apps/filetypes.c | 3 - apps/plugins/CATEGORIES | 1 + apps/plugins/imageviewer/SUBDIRS | 1 + apps/plugins/imageviewer/bmp/SOURCES | 2 + apps/plugins/imageviewer/bmp/bmp.c | 323 ++++++++++++++++++++++++++++++++++ apps/plugins/imageviewer/bmp/bmp.make | 21 +++ apps/plugins/imageviewer/bmp/bmp_ui.c | 5 + apps/plugins/imageviewer/jpeg/jpeg.c | 2 +- apps/plugins/imageviewer/png/png.c | 2 +- apps/plugins/viewers.config | 1 + apps/recorder/bmp.c | 46 ++++- 11 files changed, 396 insertions(+), 11 deletions(-) create mode 100644 apps/plugins/imageviewer/bmp/SOURCES create mode 100644 apps/plugins/imageviewer/bmp/bmp.c create mode 100644 apps/plugins/imageviewer/bmp/bmp.make create mode 100644 apps/plugins/imageviewer/bmp/bmp_ui.c (limited to 'apps') diff --git a/apps/filetypes.c b/apps/filetypes.c index e74edff5c2..49ae4afde2 100644 --- a/apps/filetypes.c +++ b/apps/filetypes.c @@ -109,9 +109,6 @@ static const struct filetype inbuilt_filetypes[] = { #ifdef HAVE_REMOTE_LCD { "rwps",FILE_ATTR_RWPS, Icon_Wps, VOICE_EXT_RWPS }, #endif -#if LCD_DEPTH > 1 - { "bmp", FILE_ATTR_BMP, Icon_Wps, VOICE_EXT_WPS }, -#endif #if CONFIG_TUNER { "fmr", FILE_ATTR_FMR, Icon_Preset, LANG_FMR }, #endif diff --git a/apps/plugins/CATEGORIES b/apps/plugins/CATEGORIES index 218055e311..4951f0db9c 100644 --- a/apps/plugins/CATEGORIES +++ b/apps/plugins/CATEGORIES @@ -3,6 +3,7 @@ autostart,apps battery_bench,apps bench_scaler,apps blackjack,games +bmp,viewers boomshine,games bounce,demos brickmania,games diff --git a/apps/plugins/imageviewer/SUBDIRS b/apps/plugins/imageviewer/SUBDIRS index 6785e47781..ca9665a022 100644 --- a/apps/plugins/imageviewer/SUBDIRS +++ b/apps/plugins/imageviewer/SUBDIRS @@ -1,3 +1,4 @@ +bmp jpeg #ifdef HAVE_LCD_COLOR png diff --git a/apps/plugins/imageviewer/bmp/SOURCES b/apps/plugins/imageviewer/bmp/SOURCES new file mode 100644 index 0000000000..a50d245846 --- /dev/null +++ b/apps/plugins/imageviewer/bmp/SOURCES @@ -0,0 +1,2 @@ +bmp_ui.c +bmp.c diff --git a/apps/plugins/imageviewer/bmp/bmp.c b/apps/plugins/imageviewer/bmp/bmp.c new file mode 100644 index 0000000000..73a4d738ac --- /dev/null +++ b/apps/plugins/imageviewer/bmp/bmp.c @@ -0,0 +1,323 @@ +/*************************************************************************** + * __________ __ ___. + * Open \______ \ ____ ____ | | _\_ |__ _______ ___ + * Source | _// _ \_/ ___\| |/ /| __ \ / _ \ \/ / + * Jukebox | | ( <_> ) \___| < | \_\ ( <_> > < < + * Firmware |____|_ /\____/ \___ >__|_ \|___ /\____/__/\_ \ + * \/ \/ \/ \/ \/ + * $Id$ + * + * BMP image viewer + * + * This program is free software;
