👎Deprecated: DXT support will be removed or reworked in a future version. Prefer the squish crate instead. See https://github.com/image-rs/image/issues/1623

What version of DXT compression are we using? Note that DXT2 and DXT4 are left away as they’re just DXT3 and DXT5 with premultiplied alpha

Variants

DXT1

👎Deprecated: DXT support will be removed or reworked in a future version. Prefer the squish crate instead. See https://github.com/image-rs/image/issues/1623

The DXT1 format. 48 bytes of RGB data in a 4x4 pixel square is compressed into an 8 byte block of DXT1 data

DXT3

👎Deprecated: DXT support will be removed or reworked in a future version. Prefer the squish crate instead. See https://github.com/image-rs/image/issues/1623

The DXT3 format. 64 bytes of RGBA data in a 4x4 pixel square is compressed into a 16 byte block of DXT3 data

DXT5

👎Deprecated: DXT support will be removed or reworked in a future version. Prefer the squish crate instead. See https://github.com/image-rs/image/issues/1623

The DXT5 format. 64 bytes of RGBA data in a 4x4 pixel square is compressed into a 16 byte block of DXT5 data

Implementations

impl DxtVariant

fn decoded_bytes_per_block(self) -> usize

👎Deprecated: DXT support will be removed or reworked in a future version. Prefer the squish crate instead. See https://github.com/image-rs/image/issues/1623

Returns the amount of bytes of raw image data that is encoded in a single DXTn block

fn encoded_bytes_per_block(self) -> usize

👎Deprecated: DXT support will be removed or reworked in a future version. Prefer the squish crate instead. See https://github.com/image-rs/image/issues/1623

Returns the amount of bytes per block of encoded DXTn data

pub fn color_type(self) -> ColorType

👎Deprecated: DXT support will be removed or reworked in a future version. Prefer the squish crate instead. See https://github.com/image-rs/image/issues/1623

Returns the color type that is stored in this DXT variant

Trait Implementations

impl Clone for DxtVariant

fn clone(&self) -> DxtVariant

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DxtVariant

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

Formats the value using the given formatter.

impl PartialEq<DxtVariant> for DxtVariant

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