# TIFF codec for HDR images

[![GoDoc](https://img.shields.io/badge/godoc-reference-blue.svg)](https://godoc.org/github.com/mdouchement/tiff)

A Golang TIFF codec for HDRi formats. This package is meant to be used with [mdouchement/hdr](https://github.com/mdouchement/hdr).

- Only decoder is implemented.

- A subset of **DNG** (Digital Negative) is supported. _There still missing parts in the basic processing workflow._

## Photometric Interpretation

- RGB - 32 bit floating point

- LogL - Luminance GrayScale (LogLuv without u & v parts)

- LogLuv - True colors (32 bits only. No support of 24 bits at the moment)

- CFA - Color Filter Array

## Compression

- None (Uncompressed)

- LZW

- Deflate (old and new)

- PackBits

- SGI Log RLE

## Architecture

|  Object | Description         |

|:-------:|---------------------|

|  reader | Decodes the image   |

| decoder | Decodes the raster  |

|   idf   | Parses the header   |

|   tag   | Parses tag's values |

## License

**BSD-style**

This package carries the same license as Golang's [image/tiff](https://github.com/golang/image/tree/master/tiff) package. Because all this package's skeleton and some piece of code come from the `image/tiff` package.
