0). Introduction
This software is originally designed for mycologists who measure the size
of spores and cystidia on microscope digital images. Now, it can also be
used for any length measurements on digital images or anything on the display
like video as far as the reference length can be taken.Since the VisualStudio
C# 2008 Express Edition is used for the development, .NET Framework 2.0
may need to be introduced to run the PhotoRuler.
The .NET Framework 2.0 download site is the follwing:
