Enum image::codecs::dxt::DXTVariant

source · [−]

pub enum DXTVariant {
    DXT1,
    DXT3,
    DXT5,
}

Expand description

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

DEPRECATED: The name of this enum will be changed to DxtVariant.

TODO: rename to DxtVariant

Variants

`DXT1`

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

`DXT3`

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

`DXT5`

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