TIFF Image Colors Are Inverted

[johnpage09]

Hi Guys,

I am using ImageJ 1.45 and when I open a TIFF Image using ImageJ (running as a Desktop app) or via a Java App that is calling the API, the image colors are Inverted.
I am able to get the original colors back by invoking Invert() but my question is why do these colors get inverted for TIFF and what setting do I need for ImageJ to show me the actual colors without having to call Invert.

Thanks & Regards,
John

The ImageJ 1.47d daily build fixes a bug that caused CMYK TIFFs to open with the colors inverted.

Hi Wayne,

Just to advise you and the other users, that the fix worked well and the TIFF images are now showing as they should.

Kind Regards,
