> , it seems this compression format is not supported. Excerpt from the
> document below:
> {quote}
> Supported through version 6.0. TIFFs is a open-ended container format, so
> it's not possible to support every possibly variation. Supports Bi-Level,
> Palette/Indexed, RGB, CMYK, YCbCr, CIELab and LOGLUV images. Supports reading
> and writing LZW, CCITT Modified Huffman/Group 3/Group 4, and Packbits/RLE
> compression. Notably missing other forms of compression though, including
> JPEG. Supports reading Tiled images.
> {quote}
> This ticket is logged to add JPEG/Zip compression format support.
