Struct RasterCandidate 

pub struct RasterCandidate {
    pub id: u32,
    pub page: u32,
    pub gray: Vec<u8>,
    pub width: u32,
    pub height: u32,
    pub hash: String,
    pub image_bbox: BoundingBox,
    pub image_index: Option<u32>,
    pub text_chunks: Vec<TextChunk>,
    pub kind: RasterCandidateKind,
    /* private fields */
}

Prepared OCR candidate for the two-phase (plan → OCR → finish) path.

Emitted when OCR can change the output (table-like or pattern-painted Image XObject). Missing OCR words at finish time degrades to PDF-text cells when a bordered grid is already known (tables only).

Fields

id: u32

Stable id within a session (0-based).

page: u32

1-based PDF page number.

gray: Vec<u8>

Grayscale pixels (row-major).

width: u32

Pixel width.

height: u32

Pixel height.

hash: String

FNV-1a hash of gray pixels (hex), for OCR result caching.

image_bbox: BoundingBox

Image placement in PDF user space.

image_index: Option<u32>

1-based Image XObject index (matches ImageChunk::index).

text_chunks: Vec<TextChunk>

Overlapping native text (PDF fallback when OCR is absent).

kind: RasterCandidateKind

How OCR words should be assembled.
