### Contour-Plotter+ ###
This package is a plugin for ImageJ ,
based on an ancient plugin .jar obtained from the
NIH site.
This package overcome the problems:
The original version by Dr. O'Dell safely analyze positive 8bit- or 16bit-integer only,
and the generated curves disappear at any further operations.
How to install
A. Relatively older imageJ
Download a .jar file, and open it
via ImageJ's menu "Plugins->install".
B. The most ImageJs
On the most systems, in turn, the following is preferable:
expand a .zip file , and
copy the folder "ContourPlotter+" into the "plugins" folder of your own ImageJ directory.
C. Fiji imageJ
If you use Fiji-imageJ,
after copying the "ContourPlotter+" folder expanded from the .zip file into your "plugins", as above,
you have to do the following step:
1) From the menu "Plugins->install.." in ImageJ menu,
select the file ContourPlotter_.java in the "plugins/ContourPlotter+"
2) and save it in "plugins" folder via "Save plugin, macros or script" dialog.
Detail of some features added
Now images fo 32bit-floating-point negative/positive values
can be analyzed as well as integer data.
The image with contour curves can now be stored as a file.
Detail:
- Negative values can be specified as a value to be drawn contour.
- As defaults, the initial contour values are intended to split the
whole gray scale into equally six-separated ranges.
Note that some number fields will not be shown
as the correct values in some cases,
because the initial format of fractional numbers is limited.
- To draw no curves for a value, choose color "NONE",
not the value to be "-1" now.
The initial values of some contours are out of range of the grayscale
(thus related noise may be only drawn unless the color is "NONE"),
which can be avoided with the color being not NONE and
the value is in the grayscale range of the target image.
- Two new integer-based RGB images are generated.
One shows the labels, while the other shows an image
with contours that can be stored as a file.
Release
Although this package can be copied freely, authors
give no warranty.
