Hi Bryce,
Submissions looks good, now merged and submitted to svn/trunk.
The only thing mising was the addition of a supportsOption(..) to the
ReaderWriterTIFF constructor, I'm guess something like:
supportsOption("no_compression","disable TIFF compression when
writing images.");
supportsOption("x_resolution <DPI>","use specified horizontal
DPI when writing images.");
supportsOption("y_resolution <DPI>","use specified vertical
DPI when writing images.");
Would be appropriate, however, I'll let you choose the exact language
as you know more about the specifics of TIFF than I do! Let me know
what you think would be apporpriate/send me a revised
ReaderWriterTIFF.cpp with the appropriate changes.
Cheers,
Robert.
