logarithmic colorscale

Hi guys,

I have an image with a certain colorscale and have ticked the log button ('ModifiyImage Image log=1'). Now I want to create a colorscale ('ColorScale image=Image,log=1') with logarithmic ticks. But when I choose logarithmic in the "Add Annotation..." Panel, the ticks are indeed logarithmic but the colorscale itself changes back to linear scaling. Is this a bug or is there a way to avoid this?

Thanks
Marty
Sounds to me like the colorscale is working as designed. The colors shouldn't be bunched up at one end like they would if the colorscale had a linear axis while the image had logarithmic color spacing.

Perhaps you should post more information and a screen shot of the offending ColorScale.

Well, after analyzing the issue I realized: everything alright with the depiction of the colorscales...

Thanks for help!
