XnView MP 0.90 - Curves - Preview not very helpful

[masterjp]

I find the usage of the curves function not very helpful. The window shows me a graph to adjust the luminance of the picture. The preview checkbox shows me a before and after picture, but I can not modify something. The only way to successfully use the graph to adjust something is to enable the "apply to image" switch.

You are saying that when the Preview option is selected the curves graph is not displayed, so it is not possible to make an adjustment?

Correct. The window is to small to compare the before and after picture. I can resize the window, but it is not very useful.
Futher there should be a maximize window button in the taskbar of the window (between ? and close symbol).

I tested the RGB mode and changed the colours on the right side. Did they do something? I will not see any difference if I switch the colours on or off.
