For potential others who may find this thread in future -- I've posted patches to hatchfill on File Exchange which seem to work for the limited testing done. Should at least be trail of bread crumbs to resolve any other issues remaining.

FYI, there's a function in the Image Processing Toolbox called VISCIRCLES which can be used for drawing circles. The basic syntax takes the centers and radii of the circles and draws them. sangeeta on 21 Mar 2013I have a binary imagen where I found 5 circles with imfindcircles and I plot them using viscircles. In order to do a least square fitting of that circle, I need to dilate this circles and get all edge pixels in a 2 pixel distance.

Accepted Answer. % Demo to have the user click and draw a circle over an image, then blacken outside the circle and crop out the circular portion into a new image. clc; % Clear the command window. close all; % Close all figures (except those of imtool.) imtool close all; % Close all imtool figures.MATLAB: Plot many filled circles. circle plot. Hello, I have n points and each of them has a radius. For each point i, i want to plot a filled circle with raduis r (i). I used viscircles to plot the circles but i can not arrive to color the inside of circles.I don't believe viscircles() offers a 'filled' option yet to make the entire disc one solid filled color. That would be a good enhancement. I believe it only draws the perimeter. ... thanks for the answer but I want just a simple command in matlab to fill a circle that is plotted with specified radius and center coordinateSelect a Web Site.
