Enum MaskEncoding 

pub enum MaskEncoding {
    None,
    Explicit,
    External,
    ImplicitAllInvalid,
}

How a decoded blob represents pixel validity.

Variants

None

Every pixel is valid and no mask is needed.

Explicit

This blob stores explicit mask bytes.

External

This blob inherits a mask supplied externally or by a preceding band.

ImplicitAllInvalid

Every pixel is invalid, represented without stored mask bytes.

Implementations

impl MaskEncoding

pub fn mask_count(self) -> u32

Returns the number of stored or implicit masks represented by this encoding.

pub fn has_mask(self) -> bool

Returns whether decoding produces a logical mask.

pub fn uses_external_mask(self) -> bool

Returns whether mask bytes must come from outside this blob.

pub fn stores_mask_bytes(self) -> bool

Returns whether the blob stores an explicit mask payload.
