may I continue post here if it is now a request for feature?

Hello,

I have a long post in the users section pertaining to my efforts to understand TIFF images and how to overcome a problem with images changing to a "negative" after processing. At the end of the post (post starting yesterday with a title similar to: "when creating thumbnails c. 15% etc...") I asked if there is a parameter in Image::Magick that can toggle the photometric interpretation in a TIFF image between min-is-white and min-is-black. If not, could it be added? I have discovered since my last post that I can run tiffset -s 262 minisblack filename.tif and it will flip that value so that Image::Magick's processing won't affect the image but am hoping for a solution within Image::Magick to a problem I realize is not caused by Image::Magick

This is a highly important endeavor for me so I hope the experts on Image::Magick can help with a parameter or some additional insight as to how IM uses that value of a TIFF file. Thanks!

We'll add -define quantum:polarity=min-is-black and -define quantum:polarity=min-is-white to the next ImageMagick point release to toggle the photometric interpretation in a TIFF image between min-is-white and min-is-black.
