}

Decoding profile for a raw .ithmb frame format.

Maps to IthmbVariantProfile in the C# implementation. Each field that defaults to false/0/None can be omitted — the decoder uses the standard behaviour unless overridden.

Fields

prefix: i32

Big-endian 4-byte prefix identifying this format.

width: i32

Frame width in pixels.

height: i32

Frame height in pixels.

encoding: Encoding

Pixel encoding.

frame_byte_length: i32

Number of bytes in one complete frame (not counting padding).

swaps_dimensions: bool

If true, width and height are swapped after decode.

little_endian: bool

If false (default), pixel data is little-endian.

is_padded: bool

If true, frame occupies a fixed-size slot with padding.

is_interlaced: bool

If true, even/odd scanlines are stored as separate fields.

clcl_chroma: bool

If true, chroma uses CLCL shared-nibble layout.

swap_chroma_planes: bool

If true, swap Cb/Cr plane order in YCbCr 4:2:0.

cl_chroma: bool

If true, chroma uses CL per-pixel nibble layout.

swap_rgb_channels: bool

If true, swap R and B channels (BGR15 iPhone compatibility).

rotation: i32

Post-decode clockwise rotation in degrees (0, 90, 180, 270).

crop_x: i32

Visible-region X offset (applied after rotation).

crop_y: i32

Visible-region Y offset (applied after rotation).

crop_width: i32

Visible-region width (0 = full width).

crop_height: i32

Visible-region height (0 = full height).

slot_size: i32

Slot size in bytes for padded profiles.

use_mhni_dimensions: bool

If true, use actual Width/Height from MHNI chunk instead of fixed values.

fallback_encodings: Option<Vec<Encoding>>

Ordered list of fallback encodings to try if primary decode fails.

Implementations

impl Profile

pub fn frame_size(&self) -> i32

The number of bytes per frame, accounting for slot padding.

For padded profiles the frame stride is slot_size; for unpadded it equals frame_byte_length.

pub fn display_width(&self) -> i32

The number of pixel columns in the frame.

pub fn display_height(&self) -> i32

The number of pixel rows in the frame.

Trait Implementations

impl Clone for Profile

fn clone(&self) -> Profile

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Profile

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

Formats the value using the given formatter.

impl Default for Profile

fn default() -> Self

Returns the “default value” for a type.
