Frame delay in units of 10 ms.

dispose: DisposalMethod

Disposal method.

transparent: Option<u8>

Transparent index (if available).

needs_user_input: bool

True if the frame needs user input to be displayed.

top: u16

Offset from the top border of the canvas.

left: u16

Methods

impl Frame<'static>

pub fn from_rgba(width: u16, height: u16, pixels: &mut [u8]) -> Frame<'static>

Creates a frame from pixels in RGBA format.

Note: This method is not optimized for speed.

pub fn from_palette_pixels(
    width: u16,
    height: u16,
    pixels: &[u8],
    palette: &[u8],
    transparent: Option<u8>
) -> Frame<'static>

Creates a frame from a palette and indexed pixels

pub fn from_indexed_pixels(
    width: u16,
    height: u16,
    pixels: &[u8],
    transparent: Option<u8>
) -> Frame<'static>

Creates a frame from indexed pixels in the global palette

pub fn from_rgb(width: u16, height: u16, pixels: &[u8]) -> Frame<'static>

Creates a frame from pixels in RGB format.

Note: This method is not optimized for speed.
