Struct RegionBlock 

pub struct RegionBlock {
    pub bbox: BoundingBox,
    pub confidence: f32,
    pub order_index: Option<u32>,
    pub element_indices: Vec<usize>,
}

A detected document region block (from PP-DocBlockLayout).

Region blocks represent hierarchical groupings of layout elements, typically columns or logical sections of a document. They are used for hierarchical reading order determination.

PP-StructureV3 Alignment

PP-DocBlockLayout detects “region” type blocks that group related layout elements together. Elements within the same region should be read together before moving to the next region.

Fields

bbox: BoundingBox

Bounding box of the region

confidence: f32

Confidence score of the detection

order_index: Option<u32>

Index of this region in the reading order

element_indices: Vec<usize>

Indices of layout elements that belong to this region
