Struct PixelDataSubBlock 

pub struct PixelDataSubBlock<'a> {
    pub data_type: DataType,
    pub data: &'a [u8],
}

A pixel-data sub-block (Table 20).

Fields

data_type: DataType

The data_type.

data: &'a [u8]

The payload data following the data_type byte. For code strings this is the entire RLE token stream including the end-of-string marker and byte-alignment stuffing. For map tables this is the fixed-size table data.

Implementations

impl<'a> PixelDataSubBlock<'a>

pub fn runs(&self) -> Option<PixelRunIter<'a>>

Decode this sub-block’s pixel runs (Tables 22-26), if it is a 2/4/8-bit pixel-data code string — None for a map-table or end-of-line sub-block, neither of which is an RLE token stream.

Yields typed PixelRuns instead of exposing data as raw RLE bytes for the caller to decode itself (#1108/DS-W5). data (the undecoded token stream, including any trailing byte-alignment stuffing) is kept as-is alongside this, since round-tripping the segment byte-exact depends on preserving it verbatim.
