Hello,
I have some comments on the way ImageJ handle the application of the contrast and threshold settings to a color stack. The behavior is inconsistent with the way these settings can be applied to a grayscale stack (by pressing the "Apply" button of the interfaces). The 4 cases I would like to comment on are:
1) Color balance: for RGB color stacks if the display settings are modified by the user in a given slice these settings are APPLIED to the slice AS SOON as the user moves the slice slider.
2) Color balance: for composite stacks the apply button has no noticeable effect (neither error message).
3) B&C: for composite stacks the apply button updates the display settings of all the channels to the display settings of the current channel (but do not apply it to any channel).
4) Color threshold: for RGB color stacks the current threshold settings are APPLIED to the slice AS SOON as the user moves the slice slider.
Referring to the 4 previous cases, I would suggest:
1) No application if the user does not press "Apply". The "Apply" button could trigger a dialog box to configure if the settings should be applied to the current slice only or to the whole stack.
2) Same as 1) - for the current channel only.
3) Same as 2)
4) Same as 1)
Are there some limitations impeding such a predictable behavior or is there a "real" logic behind the current behavior (that I did not quite get...)?
Best,
Sébastien
