Decimal Fractions in ResultsTable

[David Webster]

All,

I am trying to create/display a ResultsTable containing  or showing
decimal fractions. But, all I get are ints. I am doing something like

ResultsTable rt = new ResultsTable();
double x   = 1.0;
rt.addValue("x", x);
rt.show("My Table");

But, I don't get the x value as 1.0, only 1. How can I get the displayed
and/or "save'ed" table to have doubles in it? I notice that if rt was a
systems result
table created via "ResultsTable rt =
ResultsTable.getResultsTable()", then I get decimals freactions rather
than ints.

Hi David,

what about this?

ResultsTable.setPrecision(int precision)
Sets the number of digits to the right of decimal point.

I have a strange behaviour that only appears on one of my computers.
If I run the macro below, only a few of the larger spots will survive erosion - this is what I expect.

However, on one computer (OS X, 32 or 64 bit), the spots are dilated, not eroded. This happens even if I trash ImageJ and install a completely new version 1.43, without  custom plugins.


In all cases, spots are black(=0) on white background(=255).

Anyone who can explain this?

Hello,
could it be possible that in one case "Black Background" is selected in
Process>Binary>Options and in the other not?
Best regards,
Volker

Here only 1 seems to survive.

What is the setting of:

Process>Binary>Options...>Black background?

Is it the same in both computers?

Thank you for this advice, it solved the problem.
 - where these preferences stored ?

Hi,
I think it is in the IJ_Prefs.txt file. I am not sure in all platforms. In
linux is in the hidden folder ~/.imagej/
By the way, since I like to have black background by default, I added this and
various other options to my startupMacros.txt file, so I am sure that these
are set each time.

Cheers

G.

Micheal,

I am doing that with no luck. Could it be something to do with using a non
system ResultsTable?

Micheal/All,

Whoops, problem solved. As it turns out, if the you are writing into the
table has no fractionbalk part, the  it is written as an int. e.g. "1.00" is
entered into the table as "1" while "1.55" is entered as "1.55". I think the
software may be a little to smart for its own good.
