Enum gba::io::background::BGSize

#[repr(u16)]
pub enum BGSize {
    Zero,
    One,
    Two,
    Three,
}

The size of a background.

The meaning changes depending on if the background is Text or Affine mode.

• In text mode, the screen base block determines where to start reading the tile arrangement data (2k). Size Zero gives one screen block of use. Size One and Two cause two of them to be used (horizontally or vertically, respectively). Size Three is four blocks used, [0,1] above and then [2,3] below. Each screen base block used is always a 32x32 tile grid.
• In affine mode, the screen base block determines where to start reading data followed by the size of data as shown. The number of tiles varies according to the size used.

Variants

Zero

• Text: 256x256px (2k)

One

• Text: 512x256px (4k)
• Affine: 256x256px (1k)

Two

• Text: 256x512px (4k)
• Affine: 512x512px (4k)

Three

• Text: 512x512px (8k)
• Affine: 1024x1024px (16k)
