---------------------------------------------------------------
Does anyone have some manageable-sized, public domain files that we can use to
develop/test this capability?
Does anyone have a current need for this feature?
Through my job, I've got some interest in accessing JPEG based TIFFs. The U.S.
National Weather Service has started posting some satellite images as GeoTIFFs
containing JPEG-formatted data. I will be investigating the level-of-effort for
implementing the ability to read such files. But the task may be out-of-scope
for what I am willing to take on unless there are a significant number of
people interested in the feature.
You can find the satellite images of interest at
[GOES-East - Latest CONUS Images - NOAA / NESDIS /
STAR|https://www.star.nesdis.noaa.gov/GOES/conus.php?sat=G16]
and
[GOES Imagery Viewer - NOAA / NESDIS /
STAR|https://www.star.nesdis.noaa.gov/GOES/]
Some of the satellite-derived imagery is really quite beautiful.

> 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.
