Fields

baseline: PathBuf

Path to the baseline (expected) image

candidate: Option<PathBuf>

Path to the candidate (actual) image (required for diff, unused in crop mode)

crop: bool

Crop mode: extract a region from the baseline image instead of diffing

x: Option<u32>

X coordinate of crop region (screenshot pixels, requires –crop)

y: Option<u32>

Y coordinate of crop region (screenshot pixels, requires –crop)

crop_width: Option<u32>

Width of crop region (screenshot pixels, requires –crop)

crop_height: Option<u32>

Height of crop region (screenshot pixels, requires –crop)

format: OutputFormat

Output format (written to stdout)

output: Option<PathBuf>

Path to write visual diff image (works alongside any output format)

threshold: f64

Color difference threshold (0.0 = exact match, 1.0 = everything matches)

detect_antialias: bool

Enable anti-aliasing detection (reduces false positives at edges)

min_region_size: u32

Minimum region size in pixels (regions smaller than this are filtered out)

connectivity: u8

Connectivity for region clustering: 4 (cross) or 8 (including diagonals)

denoise: u32

Remove noise clusters smaller than this many pixels before dilation (0 = disabled)

dilate: u32

Dilation radius in pixels (expands diff mask to merge nearby changes, 0 = disabled)

merge_distance: u32

Max gap in pixels between regions to merge them (0 = disabled)

verbose: bool

Include all diagnostic fields in JSON output (dimensions, pixel counts, deltas)

pretty: bool

Pretty-print JSON output (default is compact single-line)

quiet: bool

Suppress stdout output

Trait Implementations

impl Args for Cli
