Dear ImageJ macro-coders,
ImageJ comes with an enormous amount of useful example code. However,
for many problems there exist various solutions and some are more
obvious than others...
In the here discussed situation one may follow an approach involving the
results table but the following appears more lucid and flexible, at
least to me:
Plot.getValues( x, y );
str = "X\tY\n"; // header
for ( i=0; i<x.length; i++ ) {
str += "" + x[i] + "\t" + y[i] + "\n"; }
File.saveString( str, getDirectory( "imagej" ) + "/profileData.txt" );
Instead of x[i] and y[i] one may use d2s( x[i], d ) and d2s( y[i], d ),
with d denoting the number of decimal digits.
Happy coding
Herbie
