Struct GridConfig

    pub rows: u8,
    pub columns: u8,
    pub output_width: u32,
    pub output_height: u32,
}

Grid configuration for tiled/grid-based AVIF images Grid image configuration

For tiled/grid AVIF images, this describes the grid layout. Grid images are composed of multiple AV1 image items (tiles) arranged in a rectangular grid.

Grid Layout Determination

Grid layout can be specified in two ways:

1. Explicit ImageGrid property box - contains rows, columns, and output dimensions
2. Calculated from ispe properties - when no ImageGrid box exists, dimensions are calculated by dividing the grid item’s dimensions by a tile’s dimensions

Output Dimensions

• output_width and output_height may be 0, indicating the decoder should calculate them from the tile dimensions
• When non-zero, they specify the exact output dimensions of the composed image

Fields

rows: u8

Number of tile rows (1-256)

columns: u8

Number of tile columns (1-256)

output_width: u32

Output width in pixels (0 = calculate from tiles)

output_height: u32

Output height in pixels (0 = calculate from tiles)

Trait Implementations

impl Clone for GridConfig

fn clone(&self) -> GridConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GridConfig

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

Formats the value using the given formatter.

impl PartialEq for GridConfig

fn eq(&self, other: &GridConfig) -> 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.
