makeEllipse defined by angle

[Peter van Loon]

Hi,

I like to draw an Ellipse ROI  based on center x and y (some reference to start), length, width, and angle by a macro function. The angel can make it easy for me to draw such ROI in any direction.

I found a macro to draw such ellipse at http://rsbweb.nih.gov/ij/macros/DrawEllipse.txt
Is there an equivalent to make a ellipse or rectangle ROI defined by starting point, length, width and angle?

Thanks in advance!

Peter

Hi,
For rectangles with an angle, you can try the tilted rectangle tool
available from:

Sincerely,
Jerome

Hi Peter,

here is a simple macro that draws an ellipse centered at (x=128, y=128), major and minor axes of 100 and 50, and rotated (clockwise) by 33°:

run("Specify...", "width=100 height=50 x=128 y=128 oval centered");
run("Rotate...", "angle=33");
run("Draw");

You can replace the numbers by variables with ampersands, e.g.
  "width=&majorAxis height=&minorAxis ..."

Hi Michael,


I didn't think of rotating, just that easy!
Thanks!

Hi Jerome,

Thank you for showing me this macro. Nice to know the code I like to use is already available.

Regards,
Peter
