A PNG editor from scratch (well, as close to scratch as possible).
As a decoder, this project uses the PNG test suite to validate its ability to handle various PNG features and edge cases. Currently, iris can decode and render images with an 8-bit color depth.
The renderer supports various image processing features on the GPU.
Run cargo run --release <image_path>. For example:
cargo r --release ./tests/obama.png# Profile the decoder ./profile_decoder.sh ./tests/reagan.png # Run ad-hoc benchmarks cargo r --release --bin iris-decode --features time ./tests/Periodic_table_large.png # Parse and render glyphs from the lato font file # See the generated `glyph_playground` directory. cargo r --bin iris-lato-glyphs hfkdp! # Run the PNG test suite cargo r --bin iris-png-test-suite # Fuzz the decoder ./fuzz.shhttps://www.w3.org/TR/2003/REC-PNG-20031110/
