Gary Lucas commented on IMAGING-194:
------------------------------------
I created test files using LibTIFF and ImageMagick.
Just submitted pull request 334. This change enables the reading of TIFF files
that use JPEG format for their internal coding.
Changes to be able to write files in this format will have to wait. I am
thinking that would be a separate issue.

> , 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.
