Structs

GainMapBundle

Parsed JXL gain map bundle from a jhgm container box.

Image

ImageRect

ImageRectMut

JxlAnimation

JxlBasicInfo

JxlDecoder

High level API using the typestate pattern to forbid invalid usage.

JxlDecoderInner

Low-level, less-type-safe API.

JxlDecoderLimits

Security limits for the JXL decoder to prevent resource exhaustion attacks.

JxlDecoderOptions

JxlExtraChannel

JxlFrameHeader

JxlImage

A decoded JXL image with interleaved RGBA (or GrayAlpha) u8 pixel data.

JxlImageInfo

Image metadata extracted from the file header, without decoding pixels.

JxlOutputBuffer

JxlPixelFormat

OwnedRawImage

Point

RawImageRect

Immutable view into image data. Holds a borrowed slice + row layout info. Copy because it’s just a &[u8] + dimensions.

RawImageRectMut

Mutable view into image data. Holds a borrowed mutable slice + row layout info.

Rect

ToneMapping

Unstoppable

A Stop implementation that never stops (no cooperative cancellation).

ProcessingResult

This type represents the return value of a function that reads input from a bitstream. The variant Complete indicates that the operation was completed successfully, and its return value is available. The variant NeedsMoreInput indicates that more input is needed, and the function should be called again. This variant comes with a size_hint, representing an estimate of the number of additional bytes needed, and a fallback, representing additional information that might be needed to call the function again (i.e. because it takes a decoder object by value).

RenderingIntent

Traits

ImageDataType

Image data type trait. Implementors must be “bag-of-bits” types with no padding, guaranteed by the bytemuck::Pod bound.

JxlBitstreamInput

JxlCms

JxlCmsTransformer

Stop

Cooperative cancellation check.

Functions

check_signature

Checks if the given buffer starts with a valid JPEG XL signature.

compute_md5

decode

Decode a JXL image from a byte slice to RGBA u8 pixels.

decode_with

Decode a JXL image with custom decoder options.

read_header

Read image metadata without decoding pixels.

read_header_with

Read image metadata with custom security limits.
