Struct TransformOptions 

pub struct TransformOptions {

    pub width: Option<u32>,
    pub height: Option<u32>,
    pub fit: Option<Fit>,
    pub position: Option<Position>,
    pub format: Option<MediaType>,
    pub quality: Option<u8>,
    pub background: Option<Rgba8>,

    pub auto_orient: bool,
    pub strip_metadata: bool,

    pub sharpen: Option<f32>,
    pub crop: Option<CropRegion>,
    pub deadline: Option<Duration>,
}

Raw transform options before defaulting and validation has completed.

Fields

width: Option<u32>

The desired output width in pixels.

height: Option<u32>

The desired output height in pixels.

fit: Option<Fit>

The requested resize fit mode.

position: Option<Position>

The requested positioning mode.

format: Option<MediaType>

The requested output format.

quality: Option<u8>

The requested lossy quality.

background: Option<Rgba8>

The requested background color.

rotate: Rotation

The requested extra rotation.

auto_orient: bool

Whether EXIF-based auto-orientation should run.

strip_metadata: bool

Whether metadata should be stripped from the output.

preserve_exif: bool

Whether EXIF metadata should be preserved.

blur: Option<f32>

Gaussian blur sigma.

When set, a Gaussian blur with the given sigma is applied after resizing and before encoding. Valid range is 0.1–100.0.

sharpen: Option<f32>

Unsharp-mask (sharpen) sigma.

When set, an unsharp mask with the given sigma is applied after resizing and before encoding. Valid range is 0.1–100.0. The sharpening threshold is fixed at 1.

crop: Option<CropRegion>

Optional explicit crop region applied before resize.

When set, the image is cropped to the specified rectangle before any resize operation. The crop region is validated at runtime against the decoded image dimensions.

deadline: Option<Duration>

Optional wall-clock deadline for the transform pipeline.

When set, the transform checks elapsed time at each pipeline stage and returns TransformError::LimitExceeded if the deadline is exceeded. Adapters inject this value based on their operational requirements — for example, the HTTP server sets a 30-second deadline while the CLI leaves it as None (unlimited).

Implementations

impl TransformOptions

pub fn normalize( self, input_media_type: MediaType, ) -> Result<NormalizedTransformOptions, TransformError>

Normalizes and validates the options against the input media type.

Trait Implementations

impl Clone for TransformOptions

fn clone(&self) -> TransformOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransformOptions

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

Formats the value using the given formatter.

impl Default for TransformOptions

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for TransformOptions

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