The format of the framebuffer, in graphical pixels or text-mode characters.

Variants

RgbPixel

The format of a pixel is [Pad] <Red> <Green> <Blue>, in which <Blue> occupies the least significant bits.

Each pixel is 8 bits (1 byte), so the size of the padding bits is bits_per_pixel - 24.

BgrPixel

The format of a pixel is [Pad] <Blue> <Green> <Red>, in which <Red> occupies the least significant bits.

Each pixel is 8 bits (1 byte), so the size of the padding bits is bits_per_pixel - 24.

Grayscale

The format of a pixel is [Pad] <Gray>, in which Gray is a single byte representing a grayscale value.

The size of the padding bits is bits_per_pixel - 8.

TextCharacter

The framebuffer is an EGA text-mode display comprised of 16-bit characters, not pixels.

CustomPixel

Fields

red_bit_position: u8

The bit position of the least significant bit of a pixel’s red component.

red_size_in_bits: u8

The size of a pixel’s red component, in number of bits.

green_bit_position: u8

The bit position of the least significant bit of a pixel’s green component.

green_size_in_bits: u8

The size of a pixel’s green component, in number of bits.

blue_bit_position: u8

The bit position of the least significant bit of a pixel’s blue component.

blue_size_in_bits: u8

The size of a pixel’s blue component, in number of bits.

Custom pixel format of up to 32-bit pixels.
