Struct tiff::encoder::compression::Packbits

source · [−]

pub struct Packbits;

Expand description

Compressor that uses the Packbits¹ algorithm to compress bytes.

PackBits is often ineffective on continuous tone images, including many grayscale images. In such cases, it is better to leave the image uncompressed. ↩
