From mboxrd@z Thu Jan 1 00:00:00 1970 From: Donghwa Lee Date: Thu, 10 May 2012 14:23:37 +0900 Subject: [U-Boot] [PATCH v5 1/3] LCD: display 32bpp decompressed bitmap image Message-ID: <4FAB50D9.4040709@samsung.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de This patch supports drawing 32bpp decompressed bitmap image. Signed-off-by: Donghwa Lee Signed-off-by: Kyungmin.park --- Changes for v4: - read image sequentially just as it is. Changes for v1/v2/v3: - use lcd_line_length variable - convert BGR to RGB because BMP data format aligned BGR. common/lcd.c | 19 ++++++++++++++++--- 1 files changed, 16 insertions(+), 3 deletions(-) diff --git a/common/lcd.c b/common/lcd.c index bf1a6a9..00cbf05 100644 --- a/common/lcd.c +++ b/common/lcd.c @@ -645,14 +645,14 @@ int lcd_display_bitmap(ulong bmp_image, int x, int y) bpix = NBITS(panel_info.vl_bpix); - if ((bpix != 1) && (bpix != 8) && (bpix != 16)) { + if ((bpix != 1) && (bpix != 8) && (bpix != 16) && (bpix != 32)) { printf ("Error: %d bit/pixel mode, but BMP has %d bit/pixel\n", bpix, bmp_bpix); return 1; } /* We support displaying 8bpp BMPs on 16bpp LCDs */ - if (bpix != bmp_bpix && (bmp_bpix != 8 || bpix != 16)) { + if (bpix != bmp_bpix && (bmp_bpix != 8 || bpix != 16 || bpix != 32)) { printf ("Error: %d bit/pixel mode, but BMP has %d bit/pixel\n", bpix, le16_to_cpu(bmp->header.bit_count)); @@ -669,7 +669,7 @@ int lcd_display_bitmap(ulong bmp_image, int x, int y) cmap = (ushort *)fbi->palette; #elif defined(CONFIG_MPC823) cmap = (ushort *)&(cp->lcd_cmap[255*sizeof(ushort)]); -#elif !defined(CONFIG_ATMEL_LCD) +#elif !defined(CONFIG_ATMEL_LCD) && !defined(CONFIG_EXYNOS_FB) cmap = panel_info.cmap; #endif @@ -791,6 +791,19 @@ int lcd_display_bitmap(ulong bmp_image, int x, int y) break; #endif /* CONFIG_BMP_16BPP */ +#if defined(CONFIG_BMP_32BPP) + case 32: + for (i = 0; i < height; ++i) { + for (j = 0; j < width; j++) { + *(fb++) = *(bmap++); + *(fb++) = *(bmap++); + *(fb++) = *(bmap++); + *(fb++) = *(bmap++); + } + fb -= (lcd_line_length + width * (bpix / 8)); + } + break; +#endif /* CONFIG_BMP_32BPP */ default: break; }; -- 1.7.4.1
