}

IW44 wavelet image decoding errors.

Variants

Truncated

Input ended before the IW44 stream was complete.

Invalid

The IW44 stream contains invalid data.

ChunkTooShort

A BG44/FG44/TH44 chunk is too short (fewer than 2 bytes).

HeaderTooShort

The first chunk header is too short (needs at least 9 bytes).

ZeroDimension

Image width or height is zero.

ImageTooLarge

Image dimensions exceed the safety limit.

MissingFirstChunk

A subsequent chunk was encountered before the first chunk.

InvalidSubsample

The subsample parameter must be >= 1.

MissingCodec

No codec has been initialized (no chunks decoded yet).

ZpTooShort

The ZP arithmetic coder stream is too short.

Trait Implementations

impl Debug for Iw44Error

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

Formats the value using the given formatter.

impl Display for Iw44Error

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

Formats the value using the given formatter.

impl Error for Iw44Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Iw44Error> for DjVuError

fn from(source: Iw44Error) -> Self

Converts to this type from the input type.

impl From<Iw44Error> for DocError

fn from(source: Iw44Error) -> Self

Converts to this type from the input type.

impl From<Iw44Error> for RenderError

fn from(source: Iw44Error) -> Self

Converts to this type from the input type.

impl PartialEq for Iw44Error

fn eq(&self, other: &Iw44Error) -> 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.
