Detailed Description

Video image format types.

This is the list of platform-independent image types that can be used as the lower-half of the fmt value for a kos_img_t.

Macro Definition Documentation

KOS_IMG_FMT_ARGB1555

#define KOS_IMG_FMT_ARGB1555   0x05

16-bpp interleaved A (1 bit), R (5 bits), G (5 bits), B (5 bits).

Note

This can also be used for RGB555 (with the top bit ignored).

KOS_IMG_FMT_ARGB4444

#define KOS_IMG_FMT_ARGB4444   0x04

16-bpp interleaved A/R/G/B (4 bits each).

KOS_IMG_FMT_ARGB8888

#define KOS_IMG_FMT_ARGB8888   0x02

32-bpp interleaved A/R/G/B bytes.

KOS_IMG_FMT_BGR565

#define KOS_IMG_FMT_BGR565   0x09

15-bpp interleaved B (5 bits), G (6 bits), R (5 bits).

KOS_IMG_FMT_MASK

#define KOS_IMG_FMT_MASK   0xff

Basic format mask (not an actual format value).

KOS_IMG_FMT_NONE

#define KOS_IMG_FMT_NONE   0x00

Undefined or uninitialized format.

KOS_IMG_FMT_PAL4BPP

#define KOS_IMG_FMT_PAL4BPP   0x06

Paletted, 4 bits per pixel (16 colors).

KOS_IMG_FMT_PAL8BPP

#define KOS_IMG_FMT_PAL8BPP   0x07

Paletted, 8 bits per pixel (256 colors).

KOS_IMG_FMT_RGB565

#define KOS_IMG_FMT_RGB565   0x03

16-bpp interleaved R (5 bits), G (6 bits), B (5 bits).

KOS_IMG_FMT_RGB888

#define KOS_IMG_FMT_RGB888   0x01

24-bpp interleaved R/G/B bytes.

KOS_IMG_FMT_RGBA8888

#define KOS_IMG_FMT_RGBA8888   0x10

32-bpp interleaved R/G/B/A bytes.

KOS_IMG_FMT_YUV422

#define KOS_IMG_FMT_YUV422   0x08

8-bit Y (4 bits), U (2 bits), V (2 bits).

KOS_IMG_INVERTED_X

#define KOS_IMG_INVERTED_X   0x0100

X axis of image data is inverted (stored right to left).

KOS_IMG_INVERTED_Y

#define KOS_IMG_INVERTED_Y   0x0200

Y axis of image data is inverted (stored bottom to top).

KOS_IMG_NOT_OWNER

#define KOS_IMG_NOT_OWNER   0x0400

The image is not the owner of the image data buffer.

This generally implies that the image data is stored in ROM and thus cannot be freed.
