Struct exr::image::crop::CroppedChannels

pub struct CroppedChannels<Channels> {
    pub full_channels: Channels,
    pub full_bounds: IntegerBounds,
    pub cropped_bounds: IntegerBounds,
}

A smaller window into an existing pixel storage

Fields

full_channels: Channels

The uncropped pixel storage

full_bounds: IntegerBounds

The uncropped pixel storage bounds

cropped_bounds: IntegerBounds

The cropped pixel storage bounds

Implementations

impl<Channels> CroppedChannels<Channels>

pub fn crop_layer( new_bounds: IntegerBounds, layer: Layer<Channels>, ) -> Layer<CroppedChannels<Channels>>

Wrap a layer in a cropped view with adjusted bounds, but without reallocating your pixels

Trait Implementations

impl<Channels: Clone> Clone for CroppedChannels<Channels>

fn clone(&self) -> CroppedChannels<Channels>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Channels: Debug> Debug for CroppedChannels<Channels>

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

Formats the value using the given formatter.

impl<Channels: PartialEq> PartialEq for CroppedChannels<Channels>

fn eq(&self, other: &CroppedChannels<Channels>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'slf, Channels> WritableChannels<'slf> for CroppedChannels<Channels>

where Channels: WritableChannels<'slf> + 'slf,

fn infer_channel_list(&self) -> ChannelList

Generate the file meta data for this list of channel

fn infer_level_modes(&self) -> (LevelMode, RoundingMode)

Generate the file meta data of whether and how resolution levels should be stored in the file

type Writer = CroppedWriter<<Channels as WritableChannels<'slf>>::Writer>

The type of temporary writer

fn create_writer(&'slf self, header: &Header) -> Self::Writer

Create a temporary writer for this list of channels
