I'm writing a plugin, in java (i.e., NOT a macro), and feel the need to
display results (for now, several sets of points - later, perhaps several
polylines) as an overlay. I prefer not to munge the underlying image.
Google tells me that someone implemented "ImageCanvasWithOverlay" about a year ago.
But, I also see references to "Overlay" in the ImageJ documentation, and a flurry of
changes (as recent as 1 June) that seem to be related to overlays. From what I can
gather, this overlay feature is closely coupled with ROI's. It's not entirely clear to me
that my point sets are "ROIs" - perhaps I'm confused about that?
I checked the Examples, and found a *macro* that uses the ROI manager to create an overlay.
What I need is an example that does this from a (java) plugin.
My target code for this would look something like:
createOverlay();
for(int i = 0; i < numPointSets; i++)
{
setColor(color[i]);
for(int p = 0; p < numPoints[i]; p++)
plotPoint(points[i][p];
}
showOverlay();
Bottom line: I want to display several collections of POINTS (perhaps later POLYLINES) as
an overlay.
Perhaps I need a good "plugin developers' reference manual"? Feel free to point me at one...please!
My profound apologies if such a thing exists in plain sight and I've simply missed it.
