image merge buggy

[Johannes-P. Koch]

Dear community,

upon updating my ImageJ to 1.45h, the color merger seems to ignore the
selection of the channels. This happens if I split a multi channel tiff
image and then want to merge it again in a different order. Obviously,
it always takes the same order for the channels as the image had before.
Whatever I set is ignored.

When I downgrade to 1.44 this does not happen anymore...and it did not
happen with 1.45c either (if I remember correctly).

In ImageJ 1.44n and later, the Image>Color>Merge Channels command preserves color LUTs and display ranges when creating composite images. You can avoid this behavior either by not checking "Create composite" in the dialog box, or by checking "Ignore source LUTs", an option available in the ImageJ 1.45i daily build.
