WEIRD! please help

[Ron Kramer]

I'm doing something stupid. You know we do screen transfer function.  We adjust the image by clicking the radiation icon.
It corrects the image.  OK

We then drag new instance STF down onto the bottom bar of  histogram transformation window.  DROP to apply the STF adjustments and make the image non linear.

Done it a hundred times.  NOW? when I attempt it. When I grab the new instance icon from STF window there is a black  "X"  lower right of the icon we drag to the histogram bar and it will not be accepted by the histogram trans window?

EVEN WEIRDER - I just did a screen grab and the black (white edged)  "X" doesn't appear in the capture!?!?   I DREW THE BLACK X IN - where it appears.

any idea?

Hi Ron,

OK - it would be easier with a full-screen grab - at least one that shows your source image panel, the STF panel, and the Histo panel. I feel that there is something missing due to the screen-grab that you have posted.

For example, at first glance it looks as if you have not applied the STF instance to the Histogram process, rather you have saved the instance to the desktop area. It is also not clear whether the Histogram Transform has been pointed at the same image as was used to generate the STF.

Can you give some extra information?

I'll capture the whole screen (though as a novice at this) I thought those two windows are the touble.
While the capture APPEARS I dropped it on the desktop, I explained in the text I'm dropping it on the bar and have done it hundreds of times before.

There is a strange black "X" I've never seen before. Let me try a full screen cap.   I can't shot AFTER I've applied the STF to the histogram because
that is the problem.   IT DOESN'T APPLY.
There is a "X" under the icon (I draw in a black one) since it doesn't appear in the grab!?

Here's nearly fulls screen

I think you need a "check mark" selected or enabled at lower right of Histogram Transformation window.

well ok, here's the thing - STF and HistogramTransformation are both part of the same module - IntensityTransformations - and as such can 'talk' to one another by dragging the triangle from one to the other. IIRC if you try to drag the output of one module to another, incompatible module, you get that X to indicate that the two modules can't talk to one another. for instance if you were to try to drag HistogramTransformation's triangle to StarMask, i think you should see the X.

i don't know under what circumstances HT would not accept the output from STF. what happens if you reset the STF instance and just apply that to HT? do you still get the X?

i don't think you should need the checkmark active, as that's a separate function (causes HT to 'track', that is, switch automatically to the active view as you activate different windows.)
