Enum PixelValuePolicy 

pub enum PixelValuePolicy {
    Reject,
    ClipToZero,
    Allow,
}

Policy for negative or non-finite pixel values encountered during load.

Variants

Reject

Reject the load with IoError::BadPixelValue (default). Raw detector counts are non-negative by construction, so a negative or non-finite pixel signals corruption that must be surfaced, not silently imported.

ClipToZero

Clamp negative values to 0.0, counting them in TiffLoadInfo::n_clipped_pixels. Non-finite values still error — clipping a NaN would invent data.

Allow

Accept all values verbatim. Needed for pre-normalized transmission stacks, where noise around zero legitimately produces small negative values.

Trait Implementations

impl Clone for PixelValuePolicy

fn clone(&self) -> PixelValuePolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PixelValuePolicy

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

Formats the value using the given formatter.

impl Default for PixelValuePolicy

fn default() -> PixelValuePolicy

Returns the “default value” for a type.

impl PartialEq for PixelValuePolicy

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