In
this example, the Freehand Region selector was used to pick out
the perimeter of a small feature in the sample. For systems connected
to a microscope this would start the collection of a live spectrum
from this area. For stored data, as in this example, the spectrum
from the area selected is reconstructed from the data in the SmartMap.

When
presenting your results the options of the 'Image Menu' can make
the reports you create clearer and hence more effective in communicating
their information. Reports focusing on small features contained
in an image can fail to provide all the available information, if
the optimum view is not used. In this example, the normal view of
the sample does not convey all the detail that is available for
the small particle that was analysed.

In
the report template, the image can be zoomed up to reveal details
that you want to show. The zoomed image clearly shows the particle
that was analysed and the location in which it was situated.

The
'Callipers' and 'Interaction Area' tools can add extra information
to your images to enhance your reports. The callipers can be displayed
in the image to highlight the size of features or show the distance
between objects. The interaction area serves to provide an estimate
of the region from which x-rays would be generated (full details
are in INCA Help). Allowing those reading the reports to estimate
the region from which x-ray signals would arise.

In
the Report Step of the Navigator, the 'Image Menu' includes an additional
'Annotation' item, to add and modify annotations on the image. These
options enable you to add simple text markers, and when required
move spectrum labels to prevent them from covering important details
in the image. A spectrum label can be moved by right clicking on
the blue spectrum label, selecting 'Annotation' and then 'Move Annotation'.
Next, left click on the label and drag it to its new position. The
ability to move the label is extremely valuable when the spectrum
label covers up any details that are important to see in your reports.
In the above example it is possible to further zoom up the image,
move the spectrum label so that the callipers can be placed next
to the particle to show its size. The 'Add Annotation' option can
be used to provide extra information on the images to help their
interpretation.

The
features of the 'Image Menu' are not limited to just black and white
electron images, but can apply equally as well to the colour x-ray
element maps, Cameo+ images and QuantMaps. In the following Iron
QuantMaps from a slag sample, the colour scale represents the Fe
weight percentage. The 'Image Menu' features have been used to improve
the presentation of the original Fe QuantMap and add extra details
for a report.
