+TIFF decoding and encoding library in pure Rust
+
+## Supported
+
+### Features
+- Baseline spec (other than formats and tags listed below as not supported)
+- Multipage
+- BigTIFF
+- Incremental decoding
+
+### Formats
+This table lists photometric interpretations and sample formats which are supported for encoding and decoding. The entries are `ColorType` variants for which sample bit depths are supported. Only samples where all bit depths are equal are currently supported. For example, `RGB(8)` means that the bit depth [8, 8, 8] is supported and will be interpreted as an 8 bit per channel RGB color type.

+| `PhotometricInterpretation` | UINT Format                             | IEEEFP Format             |

+## Fuzzing
+
+This crate uses [cargo-fuzz](https://github.com/rust-fuzz/cargo-fuzz) in order to test the image parser.
+
+After installing it with `cargo install cargo-fuzz` on a nightly rustc, the
+fuzzing harness can be run with recommended settings using 
+`cargo fuzz run decode_image -snone -- -timeout=5`.
