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             |

| --------------------------- | --------------------------------------- | ------------------------- |

| `WhiteIsZero`               | Gray(8\|16\|32\|64)                     | Gray(32\|64)              |

| `BlackIsZero`               | Gray(8\|16\|32\|64)                     | Gray(32\|64)              |

| `RGB`                       | RGB(8\|16\|32\|64), RGBA(8\|16\|32\|64) | RGB(32\|64), RGBA(32\|64) |

| `RGBPalette`                |                                         |                           |

| `Mask`                      |                                         |                           |

| `CMYK`                      | CMYK(8\|16\|32\|64)                     | CMYK(32\|64)              |

| `YCbCr`                     |                                         |                           |

| `CIELab`                    |                                         |                           |

## Not yet supported

Formats and interpretations not listed above or with empty entries are unsupported.

- Baseline tags

  - `ExtraSamples`

- Extension tags

## 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`.
