Compression mode of an OpenEXR file.

These modes are lossless:

• NO_COMPRESSION
• RLE_COMPRESSION
• ZIPS_COMPRESSION
• ZIP_COMPRESSION
• PIZ_COMPRESSION

These modes are lossy:

• PXR24_COMPRESSION
• B44_COMPRESSION
• B44A_COMPRESSION
• DWAA_COMPRESSION
• DWAB_COMPRESSION

And PXR24_COMPRESSION is only lossy for 32-bit floating point channels, which it converts to 24-bit floating point.

See OpenEXR’s documentation and header files for more details on the compression modes.

Trait Implementations

impl Clone for CEXR_Compression

fn clone(&self) -> CEXR_Compression

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CEXR_Compression

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

Formats the value using the given formatter.

impl Hash for CEXR_Compression

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CEXR_Compression

fn eq(&self, other: &CEXR_Compression) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
