Trait Implementations

impl Debug for RustImageData

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl RustImage for RustImageData

fn empty() -> Self

create an empty image

fn is_empty(&self) -> bool

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

Read image from file path

fn from_bytes(bytes: &[u8]) -> ImageResult<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) -> ImageResult<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, ) -> ImageResult<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 to_jpeg(&self) -> ImageResult<RustImageBuffer>

fn to_png(&self) -> ImageResult<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

fn to_bitmap(&self) -> ImageResult<RustImageBuffer>

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