    pub num_pages: usize,
    pub num_frames: usize,
    pub total_page_area: u64,
    pub used_frame_area: u64,
    pub occupancy: f64,

}

Statistics about atlas packing efficiency.

Fields

num_pages: usize

Total number of pages in the atlas.

num_frames: usize

Total number of frames (textures) packed.

total_page_area: u64

Total area of all pages (sum of width * height for each page).

used_frame_area: u64

Total area used by all frames (sum of frame width * height).

occupancy: f64

Occupancy ratio: used_frame_area / total_page_area (0.0 to 1.0). Higher is better (less wasted space).

avg_page_width: f64

Average page dimensions.

avg_page_height: f64

max_page_width: u32

Largest page dimensions.

max_page_height: u32

num_rotated: usize

Number of rotated frames.

num_trimmed: usize

Number of trimmed frames.

Implementations

impl PackStats

pub fn summary(&self) -> String

Returns a human-readable summary of the statistics.

pub fn wasted_area(&self) -> u64

Returns wasted space in pixels.

pub fn waste_percentage(&self) -> f64

Returns wasted space as a percentage (0.0 to 100.0).
