Dear Image/J Lurkers,
I'm programmatically creating three (3) OvalRoi's on a single image using the RoiManager.
As a user option, I wish to later -completely- clear all 3 ROIs from the same image.
I can successfully remove all ROIs from the RoiManager and
seemingly kill the current Roi from the ImagePlus,
but 2 of the 3 drawn ROIs still appear in the foreground color on the image.
I've tried resetting the image from its snapshot; calling updateAndRepaintWindow and
the other update/draw functions; and also tried various canvas repainting including
Graphics' clearRect, fillRect to no avail.
Any tips or incantations would be greatly appreciated.
Code fragment)
// Traverse Roi Mgr's list of Rois and select each one in turn.
// Error checking omitted
protected RoiManager rm;
...
Roi roi = new OvalRoi(circLeftRound, circTopRound, circWidthRound, circHeightRound);
imp.setRoi(roi);
rm.runCommand("Add & Draw")) // once drawn cannot be removed?
...
...
List list = rm.getList();
Hashtable rois = rm.getROIs();
for (int i = list.getItemCount() - 1; i >= 0; i--) {
String roiID = (String) list.getItem(i);
Roi roi = (Roi) rois.get(roiID);
rm.select(i);
imp.killRoi();
rm.runCommand("Delete");
} // for i
// reset image from its cached snapshot (when the plugin first ran)
handleDOUndo(); // really a fancy ipDO.reset();
imp.updateAndRepaintWindow();
cc.repaint(); // repaint the custom canvas
