Struct CachedSlide

Source

pub struct CachedSlide<R: RangeReader + 'static> { /* private fields */ }

Expand description

A slide that has been opened and cached.

This holds both the parsed slide structure and the underlying reader (wrapped in a BlockCache for efficient I/O).

Implementations§

Source §

impl<R: RangeReader + 'static> CachedSlide<R>

Source

pub fn format(&self) -> SlideFormat

Get the detected format of this slide.

Source

pub fn level_count(&self) -> usize

Get the number of pyramid levels.

Source

pub fn dimensions(&self) -> Option<(u32, u32)>

Get dimensions of the full-resolution (level 0) image.

Source

pub fn level_dimensions(&self, level: usize) -> Option<(u32, u32)>

Get dimensions of a specific level.

Source

pub fn level_downsample(&self, level: usize) -> Option<f64>

Get the downsample factor for a level.

Source

pub fn tile_size(&self, level: usize) -> Option<(u32, u32)>

Get tile size for a level.

Source

pub fn tile_count(&self, level: usize) -> Option<(u32, u32)>

Get the number of tiles in X and Y directions for a level.

Source

pub fn level_info(&self, level: usize) -> Option<LevelInfo>

Get complete information about a level.

Source

pub fn best_level_for_downsample(&self, downsample: f64) -> Option<usize>

Source

pub async fn read_tile( &self, level: usize, tile_x: u32, tile_y: u32, ) -> Result<Bytes, TiffError>

Read a tile and prepare it for JPEG decoding.

§Arguments

level - Pyramid level index (0 = highest resolution)
tile_x - Tile X coordinate (0-indexed from left)
tile_y - Tile Y coordinate (0-indexed from top)

§Returns

Complete JPEG data ready for decoding.
