Limitations

Here are the limitations:
  • Only Huffman coding with baseline DCT JPEG algorithm is supported.
  • Old style JPEG specification (Photometric Interpretation 6) is not supported. Photometric Interpretation 6 is obsolete and will be removed from the TIFF specification. Use the Photometric Interpretation 7 to incorporate the JPEG compressed images in TIFF files.
  • Additional color information, such as alpha data, is disregarded.
  • Transparency maps are ignored.
  • 8-bit gray scale and 24-bit color are supported.
  • The -crop flag is supported only when the output image type is IOCA FS 10.
