Mojo struct 🡭

Extend

@memory_only
struct Extend

How PatternSource.color_at samples outside the tile’s own [0, width) x [0, height) bounds.

REPEAT tiles the pattern in both directions. REFLECT tiles it too, mirroring alternate copies so adjacent tile edges match colors exactly (Cairo/CSS call this “mirrored repeat”). PAD extends the tile’s own edge pixels outward, the way LinearGradient/ RadialGradient extend past their axis. NONE paints nothing outside the tile: color_at returns transparent there.

Aliases

• REPEAT = Extend(Int(0))
• REFLECT = Extend(Int(1))
• PAD = Extend(Int(2))
• NONE = Extend(Int(3))

AnyType, Copyable, Deinitable, Equatable, ImplicitlyCopyable, Movable, Writable

Methods

__init__

fn def __init__(out self, value: Int)

Prefer the REPEAT/REFLECT/PAD/NONE comptime constants over constructing one directly.

Args:

• value (Int): 0 for REPEAT, 1 for REFLECT, 2 for PAD, 3 for NONE.
• self (Self)

Returns:

Self

__eq__

fn def __eq__(self, other: Self) -> Bool

Args:

• self (Self)
• other (Self)

Returns:

Bool

write_to

fn def write_to[W: Writer](self, mut writer: W)

Parameters:

• W (Writer)

Args:

• self (Self)
• writer (W)

__str__

fn def __str__(self) -> String

Args:

• self (Self)

Returns:

String
