How to view the pixel position in the ImageJ status bar for spatially calibrated images
 
|
For spatially calibrated images, is there any I can view the (uncalibrated) pixel position in the ImageJ status bar?
Today for the greyscale value, the calibrated value is shown with uncalibrated value in parenthesis. I need the spatial calibration to be viewed the same way: calibrated value with pixel value in parenthesis. Is there a plugin for this, or is it easy to fix?

Hi Stein,
if you hold the [Alt] key, the uncalibrated pixel coordinates are shown in the status bar. It is important to move the cursor after pushing down the [alt] key to update the status bar. The method getLocationAsString() at line 2158 of ImagePlus [1] creates the status message. On the fly, I don't know a method to change this, without modifying the source code of ImageJ.

Thanks, I did not know of this.
Holding the alt key gives the current XY pixel position of the cursor, but it does not provide any way to view the pixel width and height of selections, which is my main objective. It seems straightforward to change the source code to get what I need, but then I need to redo that after any new update of ImageJ. If I patch parts of the ImageJ source code, is there some tool I can use to and re-use those changes later, in a semi-automated way? I am not very experienced in maintaining java code changes. I know how to compile plugins as well as changing existing plugins, but my experience in Java ends about there.

Upgrade to the latest ImageJ daily build (1.50f27) and the pixel width and height of selections will be displayed in pixels when you press the alt or shift key. -wayne > It seems straightforward to change the source code to get what I need, but then I need to redo that after any new update of ImageJ.

Thanks,
This works as described; but the pixel width or height can still not be shown while making the selection which is what I need. Sorry for not making this clear in my original post. I cannot press the shift or alt key at the same time as making the selection, because both keys alters the way the selection is made: The former forces a quadratic selection, and the latter subtracts the new selection from the current selection. What I am looking for is an easy way to see the pixel size of selections as I create them, to make them of the desired pixel size. I think the best solution would be to always show the calibrated sizes with uncalibrated sizes in parenthesis in the status bar in the same way as it is done with calibrated greyscale values.
