Enum ProposalDownscale 

pub enum ProposalDownscale {
    Auto,
    Off,
    Factor(u32),
}

Controls optional image downscaling before proposal generation.

When markers are large in the image, the proposal stage can be run on a downscaled copy for significant speedup. All downstream stages (outer fit, decode, inner fit) still operate at full resolution.

Proposal coordinates are automatically scaled back to original image space.

Variants

Auto

Auto-select downscale factor from marker_scale.diameter_min_px.

factor = clamp(floor(d_min / 20.0), 1, 4). Ensures markers remain at least ~10 px diameter after downscaling.

Off

No downscaling (full resolution proposals).

Factor(u32)

Explicit integer downscale factor (clamped to [1, 4]).

Implementations

impl ProposalDownscale

pub fn resolve(&self, marker_scale: MarkerScalePrior) -> u32

Resolve the concrete integer factor given the current marker scale prior.

Trait Implementations

impl Clone for ProposalDownscale

fn clone(&self) -> ProposalDownscale

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProposalDownscale

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

Formats the value using the given formatter.

impl Default for ProposalDownscale

fn default() -> ProposalDownscale

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ProposalDownscale

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ProposalDownscale

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

impl Serialize for ProposalDownscale

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
