    pub tile_byte_counts_entry: Option<IfdEntry>,
    pub jpeg_tables_entry: Option<IfdEntry>,
}

A single level in the image pyramid.

Each level represents the image at a specific resolution. Level 0 is the highest resolution (full size), with higher levels being progressively smaller (lower resolution).

Fields

level_index: usize

Index of this level in the pyramid (0 = highest resolution)

ifd_index: usize

Index of the IFD in the file’s IFD chain

width: u32

Image width in pixels

height: u32

Image height in pixels

tile_width: u32

Tile width in pixels

tile_height: u32

Tile height in pixels

tiles_x: u32

Number of tiles in X direction

tiles_y: u32

Number of tiles in Y direction

tile_count: u32

Total number of tiles

downsample: f64

Downsample factor relative to level 0 (1.0 for level 0)

compression: u16

Compression scheme (7 = JPEG)

ifd: Ifd

The parsed IFD for this level

tile_offsets_entry: Option<IfdEntry>

Offset in file where TileOffsets array is stored (if not inline)

tile_byte_counts_entry: Option<IfdEntry>

Offset in file where TileByteCounts array is stored (if not inline)

jpeg_tables_entry: Option<IfdEntry>

JPEGTables entry for this level (if present)

Implementations

impl PyramidLevel

pub fn has_tile_data(&self) -> bool

Check if this level has valid tile offset and byte count entries.

pub fn tile_index(&self, tile_x: u32, tile_y: u32) -> Option<u32>

Get the tile index for a given tile coordinate.

Returns None if the coordinates are out of bounds.

pub fn tile_dimensions(&self, tile_x: u32, tile_y: u32) -> Option<(u32, u32)>

Calculate pixel dimensions of a specific tile.

Edge tiles may be smaller than tile_width/tile_height.

Trait Implementations

impl Clone for PyramidLevel

fn clone(&self) -> PyramidLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PyramidLevel

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

Formats the value using the given formatter.
