X Ray dot map inputs are connected to X Ray ports. At installation these ports
are given identifiers consistent with the XRay system in use, these identifiers
appear on the left of the window.
Each jX)rt supplies the count pulses for a selected energy window. These pulses
are accumulated on a pixel basis and used as source information for the Dot Map
function.
X Ray Data Identlfters
For convenience the text description of the port data (energy window) may be
entered by the user. These descriptions are in the column immediately to the right
of the input port identity. Just click the cursor in the edit box and the text may be
edited in the nonna] way (e.g. enter the chemical symbol). This new description
will be actioned when the DX)U5e is clicked anywhere else in the Xray window.
Dot Map Colour
Each of the Xray Ports data may be displayed in one of a number of colours. The
colour is shown in the Combo Box in the third column from the left. The colour
may be changed by clicking on the box and selecting the preferred colour.
Note that one colour is transparent, this may be chosen if the data for this X ray
port is not to be displayed, useful for presence dot maps. If the b"ansparent colour
is selected when data acquisition starts, data for that port will not be acquired.
Presence Priority
On the right of the Xray set up window is a box containing all the identities of
the non b"ansparent data sources. This window detennines the priority of the
presence dot when two or more occur in the same pixel. The top of the box is the
highest priority. The priority may be changed by selecting an entry with the
mouse and dragging it to the required priority position.
Once the data has been collected the priority may be rearranged interactively to
see the effect on the display. This is non desnuctive to the Xray data.
Grey Backed
Select grey backed if you wish to retain the grey image under the dot map.
otherwise this will be set to black.
Grey Intensity
This scroll bar adjacent to the Grey Backed check box conttols the intensity of
the grey image.
