Hi

You probably want to read in your image file (png/jpg/bmp) and then use the Picture Function VIs to draw over the image. This very simple example draws a single line over a jpeg image.

Hi Neil,

Thank you.

How to implement this in vision tools(IMAQ).

I need to measure particle angle on image.

Hari.

You might be able to use the Find Straight Edges VI - have a look for the Vision example called Straight Edge Detection for some ideas.  That will give you the position and angle of edges within your image.
