Struct TransformSpec 

pub struct TransformSpec {
    pub base_image: String,
    pub width: Option<u32>,
    pub height: Option<u32>,
    pub quality: u8,
    pub strip_dimensions: bool,
}

Transform specification for creating image variants.

Specifies how to transform a base image to create a test fixture. All fixtures in a duplicate group should use the same base image with different transforms (size, quality) to ensure CLIP sees them as duplicates.

Fields

base_image: String

Base image filename (in tests/fixtures/base/)

width: Option<u32>

Target width in pixels (None = use base image width)

height: Option<u32>

Target height in pixels (None = scale proportionally from width)

quality: u8

JPEG quality 1-100 (default 85)

strip_dimensions: bool

Strip dimension EXIF tags (for testing missing dimensions)

Implementations

impl TransformSpec

pub fn new(base_image: impl Into<String>) -> Self

Create a new transform spec with default quality.

pub fn with_size(self, width: u32, height: u32) -> Self

Set target dimensions.

pub fn with_scale(self, scale_percent: u32) -> Self

Scale to a percentage of original size.

pub fn with_quality(self, quality: u8) -> Self

Set JPEG quality.

pub fn without_dimensions(self) -> Self

Strip dimension EXIF tags from output.

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

Performs copy-assignment from source.

impl Debug for TransformSpec

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