Struct ImageRef 

pub struct ImageRef<'a> { /* private fields */ }

A loaded image file.

Can be loaded as FileRef from ROM with load_file and then cast using Into.

Implementations

impl<'a> ImageRef<'a>

pub unsafe fn from_bytes(raw: &'a [u8]) -> Self

Reinterpret raw bytes as an image.

Safety

Using this function requires a good understanding of the internal Firefly Zero binary image format. In 99% cases, you should not construct a raw image but instead load it from a [File] or generate using Canvas.

Trait Implementations

impl<'a> From<CanvasRef<'a>> for ImageRef<'a>

fn from(value: CanvasRef<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<FileRef<'a>> for ImageRef<'a>

fn from(value: FileRef<'a>) -> Self

Converts to this type from the input type.

impl Image for ImageRef<'_>

unsafe fn as_bytes(&self) -> &[u8]

Get the raw image representation.

fn sub(&self, p: Point, s: Size) -> SubImage<'_>

Get a rectangle subregion of the image.

fn transparency(&self) -> Color

The color used for transparency. If no transparency, returns Color::None.

fn pixels(&self) -> usize

The number of pixels the image has.

fn width(&self) -> u16

The image width in pixels.

fn height(&self) -> u16

The image height in pixels.

fn size(&self) -> Size

The image size in pixels.
