Merge channel problem in 1.46m

[Dr Adam Cliffe]

Hi,

I'm having trouble with merging channels in a macro at the moment. If I run
this macro

newImage("Red", "8-bit Ramp", 100, 100, 1);

newImage("Grey", "8-bit Ramp", 100, 100, 1);

run("Rotate 90 Degrees Right");

run("Merge Channels...", "c1=Red c4=Grey keep");


it should give a merged red/grey image, instead it assigns the two images
as the red and green channel.

If I do the merge by hand, using only the Red and Grey channels, it gives
the correct outcome but creates both an RGB and composite image even though
the composite option is not selected.


Anyone else having this problem?

thanks


Adam

This bug is fixed in the ImageJ 1.46n daily build.
