Fanning's LogScl routine + Colorbar?? [message #71842] Fri, 23 July 2010 10:23

Hi,

I am using the logscl to enhance the contrast of an image, something
like:

loadct,39
image = alog10(lin_image)
imdisp, logscl(image, min=min(image), max=max(image), Exponent=8,
Mean=0.65)

where image values vary from -1.34 to +2.05, with zeroes included.
The image looks nice for what I want, but how do I reflect a correct
colorbar, either for real values or the scaled ones? What is
logarithmic, the ticks or the colors?

Thanks,
Joe
