Trait Implementations

impl RustImage for RustImageData

Available on crate feature image only.

fn empty() -> Self

create an empty image

fn is_empty(&self) -> bool

fn from_path(path: &str) -> Result<Self>

Read image from file path

fn from_bytes(bytes: &[u8]) -> Result<Self>

Create a new image from a byte slice

fn from_dynamic_image(image: DynamicImage) -> Self

fn get_size(&self) -> (u32, u32)

width and height

fn thumbnail(&self, width: u32, height: u32) -> Result<Self>

Scale this image down to fit within a specific size. Returns a new image. The image’s aspect ratio is preserved. The image is scaled to the maximum possible size that fits within the bounds specified by nwidth and nheight.

fn resize(&self, width: u32, height: u32, filter: FilterType) -> Result<Self>

en: Adjust the size of the image without retaining the aspect ratio zh: 调整图片大小，不保留长宽比

fn save_to_path(&self, path: &str) -> Result<()>

fn get_dynamic_image(&self) -> Result<DynamicImage>

fn to_rgba8(&self) -> Result<RgbaImage>

fn encode_image( &self, target_color_type: ColorType, format: ImageFormat, ) -> Result<RustImageBuffer>

fn to_jpeg(&self) -> Result<RustImageBuffer>

fn to_png(&self) -> Result<RustImageBuffer>

en: Convert to png format, the returned image is a new image, and the data itself will not be modified zh: 转为 png 格式,返回的为新的图片，本身数据不会修改
