How to use Macro built in function in my plugin?

[jiajian shen]

Hi All,

Sorry to bother again.  This list really helps me a lot in ImageJ coding.

I have another question about the Marco and plugin.  I wrote a Marco code
and it runs well.  Due to some reason, I want to change the Macro to a
PluginFilter.  Now the problem is that a lot of the convenient built in
functions in Macro can not be recognized by Plugin, "makeLine(xc, yc, xb,
yb)".  My question is that where I can find the source codes of these built
in functions?  If I find these built in function source codes, I can get the
idea how these functions are built, and then I can rewrite these functions
in my plugin?  Am I right? Or is there an better way to link the Macro
functions to plugin?

Thanks a lot,
Jiajian

jiajian shen,

Explore the java API, particularly the ImagePlus and ImageProcessor classes.
They have most of what you need.

The built in macro functions are implemented in the
ij/macro/Functions.java source file, which is online at

     
http://rsbweb.nih.gov/ij/developer/source/ij/macro/Functions.java.html

You should probably convert the macro to a PlugIn rather than a
PlugInFilter.  IJ.run("Command") calls can cause "image locked" errors
in a PlugInFilter.
