Trait Implementations

impl Default for DetermineEncodingFormat

pub fn default() -> Self

Returns the "default value" for a type.

impl EncodingFormatByExtension for DetermineEncodingFormat

pub fn by_extension<P: AsRef<Path>>(
    &self,
    path: P
) -> Result<ImageOutputFormat, SicIoError>

Determines the encoding format based on the extension of the given path. If the path has no extension, it will return an error. The extension if existing is matched against the identifiers, which currently are the extensions used.

impl EncodingFormatByIdentifier for DetermineEncodingFormat

pub fn by_identifier(
    &self,
    identifier: &str
) -> Result<ImageOutputFormat, SicIoError>

Determines an image output format based on a given &str identifier. Identifiers are based on common output file extensions.

impl EncodingFormatJPEGQuality for DetermineEncodingFormat

pub fn jpeg_quality(&self) -> Result<JPEGQuality, SicIoError>

Returns a validated jpeg quality value. If no such value exists, it will return an error instead.

impl EncodingFormatPNMSampleEncoding for DetermineEncodingFormat

pub fn pnm_encoding_type(&self) -> Result<SampleEncoding, SicIoError>

Returns a pnm sample encoding type. If no such value exists, it will return an error instead.
