draw circle

[alessandra griffa]

Hi!

I am new with ImageJ plugins and I have a little problem.
Inside a plugin, I would like to draw colored circles on a grey levels
image such that the gray level image could be saved, for example as tif,
with the circles too.
Does anyone know the good class or the way I could do that?

Thank you!

Hi Alessandra,

Here is a suggestion:

1: Change the type of the gray image to a color image, that should
make the input to your plugin a ColorProcessor.
2: ColorProcessor has a method: setColor(java.awt.Color color), use
that to set the color.
3: ImageProcessor / ColorProcessor has a drawOval(int x, int y, int
width, int height), use that to draw the circle, by setting width =
height.
4: Save the image.

Thank you ! it is helpfull! but I still can not to draw waht i want.
I want to draw "results" into my Image.
dirImag=getDirectory("picture");
dirtxt=getDirectory("txt28032006_10H24");

listImag=getFileList(dirImag);
listtxt = getFileList( dirtxt );
setBatchMode(true);

run("Results... ", "open=["+dirtxt+listtxt[0]+"]");
open(dirImag+ listImag[0]);
nbr_txt = listtxt.length;
filestring=File.openAsString(dirtxt+ listtxt[0]);
rows=split(filestring, "\n");
x=newArray(rows.length);
y=newArray(rows.length);
setColor(255,200,0);
for(k=1; k<rows.length; k++)//because first is x y
{
columns=split(rows[k],"\t");
x[k]=parseInt(columns[1]);
y[k]=parseInt(columns[2]);
print(x[k],y[k]);

setColor(255,175,125);
setLineWidth(5);
drawOval(x[k], y[k], 20 ,10 );
autoUpdate(1);


}
save(dirImag+ listImag[0]+".bmp");
