Plugin Announcement: 'Alpha Channel'

[Michael Schmid]

Hi ImageJers,

since there have been occasional requests concerning an alpha channel  
in this mailinglist:

I have put a simple version online. It is NOT the equivalent to  
layers in GIMP or Photoshop. Instead, it is a plugin that uses the  
undo buffer to blend the original with the processed/pasted image.

Hello Mister Michael.

I am a new user of ImageJ. I want to use it for my thesis about offline
signature verification.

I need some help, because I have not found which is the method in the *
ij.jar*, for the menu function of binirizing a gray scale image in   thru
the ImageJ function:   *Process -->  Binary --> Make Binary.*

I also wnat to  kindly ask youfor orientation if you know the other
functions:
  *Process -->  Binary --> Skeletonize *
  *Process -->  Binary --> Fill Holes
*  *Process -->  Binary --> Dilate*


I suspect that the first I have to do is making the image binary. I want to
use those methods in my application...

Thanks a lot..
Best regards.
Hector

Hector,
You can look in the IJ_Props.txt file the exact plugin called by a given
menu command.
E.g. for 'Make Binary' menu entry :

binary01="Make Binary",ij.plugin.Thresholder

You'll find a copy of the IJ_Props.txt file in you ij.jar file or at
http://rsb.info.nih.gov/ij/download/IJ_Props.txt
Then visit the source code at
http://rsb.info.nih.gov/ij/developer/source/index.html
and go to the ij.plugin.Thresholder class.

Another option to discover which class is called by a given menu item, is to
enable the debug mode by checking the 'debug mode' checkbox under
Edit/Options/Misc... dialog, run the investigated function from the menus
and read the log output.

Good luck with you project !
