Extract x and y co-ordinates from a line profile

Paulstar008

Hello,

May I know if there is an option to extract the (x,y) co-ordinates from a line profile on a calibrated image?

Thanks for any help,

Additional info: The line is created using Auto Trace Polyline tool  under Measure tab in Image-Pro Premier V 9.2

Can you provide an image that illustrates the information that you are looking for?

Perhaps sketch it up on a piece of paper and photo or scan it and send it?

Thanks.

Dear Matt,

Here is a copy of the image. The line profile is also visible.

Thanks

Hi Paulstar008

Take a look on this post.

Dear NikitaRG,

Thanks for your suggestion. The original co-ordinates of the image ranges from (0,0) to (990,740). When I performed the measurements using the above macro, I get strange values with co-ordinates up to (2014, 813), see below. I would also like to export the values to MS excel with x and y values in two different columns for further analysis.

Thanks,

HI Paulstar008,

If you want to print coordinates in 2 columns, use Matt's code (from the same topic):

'Output the CURRENT BOUDARY POINT
                        s = _
                            p.x.ToString("F2") & vbTab & _
                            p.y.ToString("F2")
                        ThisApplication.Output.PrintMessage(s)

Then you can export the Output window to Excel.
Note, that the coordinates are in Pixels, that may explain 2014,813.

The information below may help also.

All of these IMPORTS may not be needed but these are in the PROJECT / APP that includes this CODE so I am showing them below.

You can replace the IMAGE WIDTH and IMAGE HEIGHT (in PIXELS) with the X COORDINATES and Y COORDINATES (in PIXELS) to get the CALIBRATED versions of the X COORDINATES and Y COORDINATES.

I hope this information is helpful

Thank you Yuri and Matt for your kind support. As I am not that familiar with macros, perhaps you can provide a little bit more information on how I can implement the above.
Thanks,

Writing a MACRO to EXTRACT and REPORT the DATA that you are looking for (as I understand the challenge) would take about 30 to 60 minutes for a basic routine that would handle 1 LINE in 1 IMAGE.

This is a bit too big a project for me to tackle for the FORUM.

MEDIA CYBERNETICS holds MACRO PROGRAMMING CLASSES for IMAGE-PRO a couple of times each year for a fee.

ALCES IMAGING AND AUTOMATION provides MACRO PROGRAMMING SERVICES for IMAGE-PRO for a fee.

I hope this information is helpful.
