Turbo Gray Image Format
Simple CLI program to decode grayscale images 🚀 blazingly fast 🚀
On my old i7-4700MQ CPU @ 2.40GHz I could achieve a decoding speed of 0.75 [GBit/s] using a single core and 2.3 [Gbit/s] using all 4 cores.
The encoding speed is 0.4 [GBit/s] on my machine and there
Uses Rice-Coding with delta filter and bit-padding to enable parallel decoding.
# Example usage
tgif input.png output.tgif --rem-bits 2 --chunk-size 128
tgif input.tgif output.png
# Use cargo to build the project
cargo run --release -- help
Usage: tgif [OPTIONS] <SRC> <DST>
Arguments:
<SRC> Input image (eg: TGIF, PNG, ...)
<DST> Output image (eg: TGIF, PNG, ...)
Options:
-r, --rem-bits <REM_BITS> Number of bits used to encode the remainder. Should be 0..=7. [Default: 2]
-c, --chunk-size <CHUNK_SIZE> Size of self contained chunk in Kibibyte. Should be equal to L1 cache size. [Default: 128]
