Enum iconwriter::Image

pub enum Image {
    Raster(DynamicImage),
    Svg(Tree),
}

A uniun type for raster and vector graphics.

Variants

Raster(DynamicImage)

A generic raster image.

Svg(Tree)

A svg-encoded vector image.

Implementations

impl Image

pub fn open<P: AsRef<Path>>(path: P) -> Result<Self, Error>

Attempts to create a Image from a given path.

Return Value

• Returns Ok(src) if the file indicated by the path argument could be successfully parsed into an image.
• Returns Err(io::Error::from(io::ErrorKind::Other)) if the image allocation failed or if the file was not able to be accessed.
• Returns Err(io::Error::from(io::ErrorKind::InvalidInput)) if the image format is not supported by iconwriter.
• Returns Err(io::Error::from(io::ErrorKind::InvalidData)) otherwise.

Example

let img = Image::open("source.png")?;

pub fn rasterize<F: FnMut(&DynamicImage, u32) -> Result<DynamicImage>>(
    &self,
    filter: F,
    size: u32
) -> Result<DynamicImage, ResampleError>

Rasterizes the Image to a DynamicImage.

For raster graphics the moethod simply applies the resampling filter specified by the filter argument. For vector graphics, the method rasterizes the image to fit the dimensions specified size using linear interpolation and antialiasing.

pub fn width(&self) -> f64

Returns the width of the image in pixels.

pub fn height(&self) -> f64

Returns the height of the image in pixels.

pub fn dimensions(&self) -> (f64, f64)

Returns the dimensions of the image in pixels.
