ROI Creation

[David Webster]

All,

Could someone point me to the ImageJ API code that deals with reading the
xy coordinates of the cursor as it is used to trace an ROI. I want the code
the generates an xy coordinates list, not the creation of an ROI itself.

Hi David,

ok, for the freehand ROI:

See ImageCanvas.mouseDragged, it calls
Roi.handleMouseDrag, which calls (during the construction phase of the ROI)
FreehandRoi.grow. Finally, that's where the coordinates xp, yp are calculated.

If you want to create a plugin that records the mouse movement (while the button is down), it would be easiest if you create a PlugInTool and simply have a mouseDragged method that records the coordinates.

This seems to be what I have been looking for.

Thanks. - David
