Enum Htj2k97CodeBlockOptionsError 

#[non_exhaustive]
pub enum Htj2k97CodeBlockOptionsError {
    NumericOptionsOutOfRange,
    QuantizationOptionsOutOfRange,
    DimensionExponentUnsupported {
        axis: Htj2k97CodeBlockAxis,
        exponent_minus_two: u8,
    },
    DimensionsExceedLimits {

    },
}

Failure returned when shared HTJ2K 9/7 code-block options are unsupported.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NumericOptionsOutOfRange

Bit depth, guard bits, or the global quantization scale is unsupported.

QuantizationOptionsOutOfRange

A subband scale, derived delta, or declared bitplane count is unsupported.

DimensionExponentUnsupported

A dimension exponent cannot be represented by the host index type.

Fields

axis: Htj2k97CodeBlockAxis

Dimension whose exponent was rejected.

exponent_minus_two: u8

JPEG 2000 code-block exponent minus two.

DimensionsExceedLimits

Decoded code-block dimensions exceed the HTJ2K side or area limit.

Fields

width: usize

Decoded code-block width.

height: usize

Decoded code-block height.
