The Line Profile Properties dialog offers
options for controlling the way the Line Profile is calculated and
how it is drawn. Although the window's title is unique, this is the
common
Marker Properties Dialog that is shared with other
drawing procedures in Mira , including the
Distance & Angle measurement.
Open the Line Profile Properties dialog
by clicking on the
Line Profile Toolbar.
Drawing Properties
The Drawing Properties control the way the line and
its text are displayed on the image.
Drawing Properties of Line Profile
Plots
Drawing Mode
Select the mode which controls the interaction of
the color "pen" and the image on the screen.
Line Width
Specify the line width in units of screen
pixels.
Marker Size
This general feature is disabled for line profile
plots.
Hit Radius
Specify the radius in screen pixels in which the
mouse arrow is is deemed to have hit a drawn line. This is used for
highlighting the line in Move mode.
[Marker]
Opens a Color Selector for choosing the
line color.
[Font]

label's font.
Centroid Properties
The Centroid Properties control the way the line

Plots
Centroid First Point
Check this box to make the line begin at a
centroid coordinate calculated near the point where the mouse
started the line.
Centroid Last Point
Check this box to make the line end at a centroid
coordinate calculated near the point where the mouse ended the
line.
Centroid direction:
These bullets control the assumption about the
value of feature relative to the background. Usually, the centroid
is done on positive (bright) features or points.
Positive: The
centroid is computed for a source brighter than the background.
Negative: The
centroid is computed for a source darker than the background.
Sample Radius
Specifies the radius over which the centroid
calculation samples the pixel data for intensity information.
