IGOR Pro 7 bug?

Tue, 08/02/2016 - 09:27 am

Hi!

I was playing around with the (demo) version of Igor Pro 7 and noticed a "weird" behaviour different from what I am used to in Igor 6, which may be a bug.
When displaying an image and using the "Log Colors" option, the "Before First Color" and "After Last Color" options do not work as expected.

I have a matrix of values between [0, 4500], limiting the first and last color values to [1,3000] and using "Log Colors" as well as "Reverse Colors" options, setting the "Before First Color" to yellow and "After Last Color" to red it shows an image with values above 3000 in red which is correct, but also points with value 0 are shown in red. In Igor 6 it would be shown in yellow, what I would also expect since value 0 corresponds to "Before First Color".

The funny thing is that it works as expected using "Log Colors" without the "Reverse Colors" option ...
