Curve Tool mysterious x: - Laserulo - 12-16-2017
When I open my curve tool I find there is a vertical line with the label 'x:193' where the number is a position on the horizontal axis. This position is never the same i.e. it varies from one image to another. I've tried to deduce what it means but am at a loss. Gimp context help provides no clues. Any suggestions?

Welcome to gimp-forum.net
Which version of linux are you using and which version of Gimp?

Thanks rich2005
version 2.8.16
Typically after puzzling over this for a while I happened upon the answer myself immediately after asking the question!
It seems to be that the x: marks the value of the point on the image where I click to open the curves dialogue. If I select curves from the colour drop-down menu the vertical line doesn't appear.

Yes, actually very useful for accurate work. You can re-click on the canvas to get the value for another pixel...
