From 13209604c1512658e729d0bd9f1c54cf3e53568d Mon Sep 17 00:00:00 2001 From: Thomas Martitz Date: Tue, 8 Nov 2011 21:34:46 +0000 Subject: Add new lcd_bmp and lcd_bmp_part APIs. This new APIs wrap around lcd_[mono|transparent]_bitmap/_part calls and handle all kinds bitmaps. The intended use is to draw bitmaps that come from read_bmp_fd/_file. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30936 a1c6a512-1295-4272-9138-f99709370657 --- firmware/drivers/lcd-16bit-common.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) (limited to 'firmware/drivers/lcd-16bit-common.c') diff --git a/firmware/drivers/lcd-16bit-common.c b/firmware/drivers/lcd-16bit-common.c index 1e1548e997..bbac2b295a 100644 --- a/firmware/drivers/lcd-16bit-common.c +++ b/firmware/drivers/lcd-16bit-common.c @@ -515,3 +515,21 @@ void ICODE_ATTR lcd_alpha_bitmap_part(const unsigned char *src, int src_x, #endif } while (--row); } + +/* Draw a partial bitmap (mono or native) including alpha channel */ +void ICODE_ATTR lcd_bmp_part(const struct bitmap* bm, int src_x, int src_y, + int x, int y, int width, int height) +{ + int bitmap_stride = STRIDE_MAIN(bm->width, bm->height); + if (bm->format == FORMAT_MONO) + lcd_mono_bitmap_part(bm->data, src_x, src_y, bitmap_stride, x, y, width, height); + else + lcd_bitmap_transparent_part((fb_data*)bm->data, + src_x, src_y, bitmap_stride, x, y, width, height); +} + +/* Draw a native bitmap with alpha channel */ +void ICODE_ATTR lcd_bmp(const struct bitmap *bmp, int x, int y) +{ + lcd_bmp_part(bmp, 0, 0, x, y, bmp->width, bmp->height); +} -- cgit v1.2.3
