ROI Manager problem

Michal Lijowski
I have a problem with ROI Manager in ImageJ 1.37f
on FC4 Linux and Sun JDK1.6.0.
First, I tried to draw ROIs which I selected and saved
about one year ago using ImageJ version available at that
time. This does not seem to work. After being opened
in ROI Manager some of them are not being drawn.

So, I tried to start over and in Analyze -> Set Measurements
I checked Area, Mean, Standard Deviation, Min & Max Gray Value,
Center of Mass, Bounding Rectangle, Integrated Density, and
Redirect To None.

I draw ROI with Freehand line, click Add in ROI Manager, click
on ROI title to select it, click Measure, and in Results window
I get the following in the title

      Mean   StdDev  Min    Max      BX  BY  Width Height  Angle Length

and no IntDensity.

Integrated density is not available with line selections. You need to
create the selection using one of the area selection tools, which are
the first four tools on the tool bar plus the wand tool.
