From 6724de2dbabadf41453c650e341dfe4fb5e7968c Mon Sep 17 00:00:00 2001 From: unhelpful Date: Wed, 6 May 2009 04:53:56 +0000 Subject: [PATCH] Move YUV->RGB in JPEG load from before scaler to after scaler. Required change to struct custom_format, so sorted the plugin API as well. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@20856 a1c6a512-1295-4272-9138-f99709370657 --- apps/plugin.c | 30 +++++++++++--------------- apps/plugin.h | 45 +++++++++++++++++---------------------- apps/plugins/jpeg/yuv2rgb.c | 7 ------- apps/plugins/pictureflow.c | 30 ++++++++++++++++++++++++++ apps/recorder/bmp.c | 2 +- apps/recorder/jpeg_common.h | 51 +++++++++++++++++++++++++++++++++++++++++++++ apps/recorder/jpeg_load.c | 32 +++------------------------- apps/recorder/resize.c | 47 +++++++++++++++++++++++++++++++++++++++++ apps/recorder/resize.h | 11 ++++++++++ 9 files changed, 174 insertions(+), 81 deletions(-) diff --git a/apps/plugin.c b/apps/plugin.c index 2d996a404..f079e849b 100644 --- a/apps/plugin.c +++ b/apps/plugin.c @@ -135,11 +135,18 @@ static const struct plugin_api rockbox_api = { lcd_blit_mono, lcd_blit_grey_phase, #endif /* LCD_DEPTH */ +#if defined(HAVE_LCD_MODES) && (HAVE_LCD_MODES & LCD_MODE_PAL256) + lcd_blit_pal256, + lcd_pal256_update_pal, +#endif lcd_puts_style, lcd_puts_scroll_style, #ifdef HAVE_LCD_INVERT lcd_set_invert_display, #endif /* HAVE_LCD_INVERT */ +#if defined(HAVE_LCD_MODES) + lcd_set_mode, +#endif #if defined(HAVE_LCD_ENABLE) || defined(HAVE_LCD_SLEEP) lcd_activation_set_hook, &button_queue, @@ -571,6 +578,11 @@ static const struct plugin_api rockbox_api = { #endif #ifdef HAVE_LCD_BITMAP read_bmp_file, + read_bmp_fd, +#ifdef HAVE_JPEG + read_jpeg_file, + read_jpeg_fd, +#endif screen_dump_set_hook, #endif show_logo, @@ -632,24 +644,6 @@ static const struct plugin_api rockbox_api = { appsversion, /* new stuff at the end, sort into place next time the API gets incompatible */ - -#if defined(HAVE_LCD_MODES) - lcd_set_mode, -#endif - -#if defined(HAVE_LCD_MODES) -#if HAVE_LCD_MODES & LCD_MODE_PAL256 - lcd_blit_pal256, - lcd_pal256_update_pal, -#endif -#endif -#ifdef HAVE_LCD_BITMAP -#ifdef HAVE_JPEG - read_jpeg_file, - read_jpeg_fd, -#endif - read_bmp_fd, -#endif };
