Struct Trim 

pub struct Trim { /* private fields */ }

Options for finding a trim box.

Implementations

impl Trim

pub const fn with_background(self, rgba: [u8; 4]) -> Trim

Trim this RGBA colour rather than the top-left pixel’s.

pub fn with_threshold(self, threshold: f32) -> Result<Trim, PixelsError>

How far, in 8-bit units at any depth, a channel may differ from the background and still be background.

Errors

Returns PixelsError::InvalidArgument unless threshold is finite and not negative.

pub const fn line_art(self, line_art: bool) -> Trim

Skip the median, so a line one pixel wide counts as content (sharp’s lineArt).

pub fn find(&self, tile: &Tile<'_>) -> Result<Option<Region>, PixelsError>

The box of tile that is not background, in the tile’s coordinates, or None if every pixel is background (sharp then leaves the image alone).

Errors

Returns PixelsError::InvalidArgument for an image narrower and shorter than 3 pixels, which sharp refuses too.

Trait Implementations

impl Clone for Trim

fn clone(&self) -> Trim

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Trim

impl Debug for Trim

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

Formats the value using the given formatter.

impl Default for Trim

fn default() -> Trim

sharp’s defaults: the top-left pixel is the background, the threshold is 10, and the image is not line art.

impl PartialEq for Trim

fn eq(&self, other: &Trim) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
