any way to measure blood vessel diameter via automation

[Best, Derek]

I was wondering if there is a way to measure blood vessel diameter via an
automated macro for image J?

Hi all,

It looks like opening a Jpeg via ImageJ API, and saving it to a file
increases the size of the image.  For example, I have an original file size
of 15,823.  Just opening it via Opener class, and saving the ImagePlus
object to a file via FileSaver class makes the image size to be 95,684!  

Please let me know if there is away around to keep the original file size.

Best regards,
Bilal
