Draw Circle Using Array

[Jack83sg]

Hi,

I have a sizeable array which has an N by N size. How can I draw a circle in my array using digits, 0 or 255, in U8 representation?

I have a Flatten Pixmap.vi and Draw Flatten Pixmap.vi to assist in the drawing.

So hope someone out there can help to enlighten me in the logic.

Thanks and Regards,

Jack

There is a function for the 2D picture control that draws real nice circles. You can then turn that picture into whatever you want.

What is it that you are trying to accomplish?

Hi Mike,

Actually I am trying to extract out a jpeg image which has a circle in it and the size varies. The jpeg image is quite standard, but the circle size varies.

I have converted the image to 8bit pixmap array in grayscale format. But some of the arc of the circle has gone missing due to some colors overlapped the arc color.

So I want to get back the black circumference instead of the overlapping color.

I have attached a sample for reference.
