Vision ROI point size

[albertolv]

Good Morning,

it's possible to change the size of ROI points on vision image display. The point is too small.

I cannot use alternative ROI eg. circle because I need that the user move the ROI point.

The best would also be to change the color of the points (eg. red and green at the same time).

Thank you, have a nice day.

I'm unsure if you are asking a question, or making a statement.  You seem to be wanting to create a Region of Interest consisting of a single point on an Image.  Are you asking how to "magnify" part of an Image (perhaps by changing single pixels into a square array of 2x2, 3x3, 10x10, or whatever identical pixels) so you can select more easily a single pixel?

If this is your question, it would help for you to say so, to show what you've tried, and to include a sample Image.

I've extract the contour of a piece like in image.

I've approximate the extract contour in lines and arcs.

I need that the user can be adjust the contour moving the main points of figure.

I had thought of moving control points as roi and drawing arcs and lines as overlays.

The question is: it's possible to enlarge the size and width of point roi in image display?

Any suggestion for permit the user to modify the contour directly over the image?

Thank you

Alberto

What you need is a Consultant.  The Forum can serve as an "unpaid Consultant", but you need to do what you'd do if you were paying a Consultant -- you need to provide as much information as you can.  This means you need to attach the Image File (not a "picture" of the Image), the VIs that you are using (again, not pictures -- you may need to include many VIs, which is best done by compressing the folder containing them all and attaching the ZIP file), and explain enough that someone who knows a bit about Image Processing can follow your code.
