Translate command in ROI Manager

We have a question regarding the Translate command within the ROI Manager.

Our goal is to select a single or group of ROIs in the manager and move them. Is this what the translate command does?

We have tried selecting one ROI and translating it, but 1.) nothing happens and 2.) we don't see a macro command generated in the Recorder window.

Is this a bug with the command or are we using it incorrectly? Any help appreciated.

We are using ImageJ 1.52t23, Java 1.8, Win10

Thank you!

Re: Translate command in ROI Manager

Hi Michael,

after the RoiManager's More>>translate, you have to select the roi again
(or deselect/select, if it was selected) to make it active in the image.

It seems that the macro command was forgotten in the documentation of
the macro language:

roiManager("select",0);
roiManager("translate",5,10); //translate the selected roi(s)
roiManager("select",0); //make it the roi active for the image

The Roi Manager's translate even accepts decimals (subpixel accuracy),
and interesting enough, it can even create rectangles with non-integer
positions. But they are not useful; for using as a selection their
coordinates are rounded down to an integer.

Thank you!

The colleague I was helping with macro programming got this to work perfectly.

Cheers-

In reply to this post by Cammer, Michael-2

I have found that macro wich might be useful :

Dialog.create("Move Selections");
Dialog.addNumber("X Displacement:", dx);
Dialog.addNumber("Y Displacement:", dy);
Dialog.show();
dx = Dialog.getNumber();
dy = Dialog.getNumber();;
n = roiManager("count");
if (n==0)
exit("The ROI Manager is empty");
for (i=0; i<n; i++) {
roiManager('select', i);
getSelectionBounds(x, y, w, h);
setSelectionLocation(x+dx, y+dy);
roiManager('Add');
}

All the best,

Fabrice.

Re: Translate command in ROI Manager

Hi Fabrice,
How are you doing?
Happy New Year 2020!!!
For beginners your copied macro may be quite problematic to use since it will only work in the case a picture is open together with the roiManager containing at least an element.
On top of this it will throw and error since the parameters dx and dy used within the two Dialog.addNumber lines are undefined.
Thus prior to your copied code, you need to add something like:
dx = dy = 0;
Have a nice week-end.
My best regards,
Philippe
