Struct HdimImage 

pub struct HdimImage {
    pub path: PathBuf,
    pub data: Arc<DynamicImage>,
    pub width: u32,
    pub height: u32,
    pub adjustments: Adjustments,
    pub history: History,
}

The primary image structure used for editing sessions.

HdimImage wraps a DynamicImage and maintains its adjustment state and modification history.

Fields

path: PathBuf

Original path of the image on disk.

data: Arc<DynamicImage>

Raw image data loaded into memory.

width: u32

Width of the image in pixels.

height: u32

Height of the image in pixels.

adjustments: Adjustments

Current set of adjustments applied to the image.

history: History

History of image states for undo/redo functionality.

Implementations

impl HdimImage

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

Creates a new HdimImage by loading it from a file path.

Errors

Returns an error if the image cannot be opened or decoded by the image crate.

Examples

use hdim_core::HdimImage;
use std::path::Path;

let path = Path::new("tests/images/4k.jpg");
let hdim_image = HdimImage::from_path(path).unwrap();

pub fn record_state(&mut self)

Records the current image state and adjustments into history.

pub fn undo(&mut self) -> bool

Moves one step backward in history and updates the current state.

pub fn redo(&mut self) -> bool

Moves one step forward in history and updates the current state.

pub fn transform_image(&mut self, transform: &TransformState)

Permanently applies a TransformState to the base image data.

pub fn apply_adjustments(&self) -> DynamicImage

Applies the current set of Adjustments to the raw image data.

This method performs a sequential application of light, color, and effect transformations, returning a new DynamicImage.

Examples

use hdim_core::HdimImage;
use std::path::Path;

let path = Path::new("tests/images/4k.jpg");
let mut hdim_image = HdimImage::from_path(path).unwrap();
hdim_image.adjustments.brightness = 10.0;
let adjusted = hdim_image.apply_adjustments();

pub fn save_with_exif( &self, path: &Path, format: ImageFormat, strip: bool, ) -> Result<()>

Saves the image with the current adjustments and handles EXIF metadata.

If the exif feature is enabled, this method will attempt to preserve or strip EXIF data based on the strip argument.

Arguments

• path - The destination path for the saved image.
• format - The image format to use for saving.
• strip - Whether to strip sensitive EXIF data.

Errors

Returns an error if the image cannot be saved or if EXIF handling fails.
