Cross-Platform Image Measurement
Introduction
This is a program for measuring the widths between tree-rings, or any other distance you might fancy. It is written in C++ and uses the excellent wxWindows library which means it compiles on both Win32 and under GNU/Linux.
Downloads
The Win32 binary
This was compiled with Microsoft Visual C++ 7.0.
You will need Microsoft VC7 runtime libraries to use it.
You do not need to install the wxWindows library as it is statically linked.
The x86 Linux Binary
This was compiled with gcc (g++) 3.3.4.
You will need the wxWindows library to use it.
The Source Tarball
I used emacs to write this.
It's a bit messy, but should be easy enough to modify.
