Dear all,
i was wondering how some important functions like color swap is not there?
or, am i missing something. i am analyzing some microscopic slides
containing blood vessels filled with pink RBCs which i wanted to convert to
black object. But I could only select all pink RBCs by color based
thresholding function. but then i can not convert them to black by any easy
method without affecting other parts of histology.

and another important query: is there any way to increase the window level
of wand tracing tool. if the color values change little bit higher or lower
the wand tool cant able to detect them making it non-functional in many
important situations. In adobe it can be done nicely.

any hint or help will be beneficial and i can try our myself after that.
Please suggest something.
thanks for noticing.
