GoDoc

A Golang TIFF codec for HDRi formats. This package is meant to be used with mdouchement/hdr.

  • 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
