Detailed Description

What one buffer has had written since gfx_damage_reset().

Field Documentation

all

bool gfx_damage_t::all

the whole buffer counts as written

bands

int16_t gfx_damage_t::bands

bands in use: height / 16, rounded up

base

uintptr_t gfx_damage_t::base

the buffer's first pixel, as an address

end

uintptr_t gfx_damage_t::end

one past its last row, as an address

height

int16_t gfx_damage_t::height

its height, rows

hi

int16_t gfx_damage_t::hi[GFX_DAMAGE_MAX_BANDS]

one past its last written x

last

uintptr_t gfx_damage_t::last

the pixels of the canvas last translated

last_x

int16_t gfx_damage_t::last_x

that canvas's left edge in the buffer

last_y

int16_t gfx_damage_t::last_y

its top edge in the buffer

lo

int16_t gfx_damage_t::lo[GFX_DAMAGE_MAX_BANDS]

a band's first written x, or width when nothing is

stride

int32_t gfx_damage_t::stride

pixels from one row to the next

width

int16_t gfx_damage_t::width

the buffer's width, pixels
