Struct jpeg2k::DecodeParameters

pub struct DecodeParameters { /* private fields */ }

Implementations

impl DecodeParameters

pub fn new() -> Self

pub fn reduce(self, reduce: u32) -> Self

How much to reduce the image’s resolution.

If reduce == 0, image is decoded to the full resolution. This is the default. If reduce > 0, then original dimension divided by 2^(reduce)

pub fn strict(self, strict: bool) -> Self

Enable/disable strict decoing mode.

If disabled then progressive downloading is supported (truncated codestreams). This is the default. If enabled then partial/truncated codestreams will return an error.

pub fn layers(self, layers: u32) -> Self

The number of quality layers to decode.

If there are less quality layers than the specified number, all the quality layers are decoded.

If layers == 0, all the quality layers are decoded. This is the default. If layers > 0, then only the first layers layers are decoded.

pub fn decode_area(self, area: Option<DecodeArea>) -> Self

The area to decode.

If area == None, then the whole image will be decoded. This is the defult.
