Set min/max does not work via the GUI for large 32-bit images
 
|
I found a bug which seems to be connected to the GUI since it works fine in a macro:
If you try to set the contrast range (Min/Max values) in the Brightness/Contrast dialog, the values always revert to the previous values if the image is 32 bit and the edges are several thousand pixels length. Here is a macro reproducing the issue: run("M51 Galaxy (177K, 16-bits)"); run("32-bit"); run("Scale...", "x=10 y=10 interpolation=Bilinear average create"); run("Brightness/Contrast..."); waitForUser("Now please try to set a fixed min/max range of 0/1000\n using the Set button in the Brightness/Contrast dialog"); //this does not work, the min/max values revert to the previous values //setting it via macro works fine however: //setMinAndMax(0, 1000); I am using daily build ImageJ 1.51u with Java 1.6 on Windows 7/64-bit.

Hi Stein,
sorry, I could not reproduce this, neither on Linux (Java 1.8) nor on Win 10 (Java 1.6). I also tried different '16-bit range' settings in Edit>Options>Appearance (automatic and 12 bit), to see whether the range of the input image makes a difference, it seems it does not. I even tried with a scale of 60 (2.2 GB image size). Then, image updating on the screen has a problem under Linux (at magnifications <below 4%; probably related to the Intel graphics), but the B&C limits are fine. What I noticed, however: If the B&C is opened the first time in a session, it does 'Auto' brightness. Later, there is no auto B&C scaling.

Ok, I will test it on Windows 10 to see if it is a Windows 7 issue (which is what I normally use).
I also get Auto brightness the first time B&C is opened; the problem is that it gets stuck in Auto brightness. I forgot to mention that If I successfully set the min-max using a macro; subsequent usage of the B&C dialog work correctly. So this problem only occurs mainly on a freshly opened ImageJ instance.

I can reproduce the problem using Windows7(Java1.8). When I set the values as suggested they seem to be set but directly revert back to the precious values.
