Transfer Function Properties
The Transfer Function Properties dialog sets
global default properties for transfer functions used by new image
windows. The properties exposed in this dialog are the same as
those in the transfer function panes except for the addition of the
profile control to save and recall default parameter sets.
Default Transfer Function Properties
|
Profile [|>]
|
Selects the parameter profile for this command and
allows you to save or work with existing presets.
|
Sample
|
The Sample control determines the region where the
image intensity is sampled for calculating the transfer function.
The options are as follows:
Full Image: Samples
the entire image.
Cursor: Samples the
region inside the
Image Cursor.
Cursor Live: Samples
the region inside the
Image Cursor and updates as the cursor moves. This
slows cursor movement.
|
Range
|
The Range specifies how the intensity limits are
calculated from the sample region. One of the options allows you to
force the minimum and maximum to specific values.
|
Stretch
|
The Stretch provides options for extending the
transfer function to higher or lower intensity. The options are as
follows:
Linear: Uses no Bias
with equal Grayscale spacing between the transfer function's
limiting values.
Log: Extends the
transfer function to greater contrast at lower intensity
values.
Gamma: Extends the
transfer function to higher or lower intensity based on the gamma
setting. A gamma less than 1 biases toward higher contrast in lower
intensity, and vice versa.
|
Boost
|
Check this box to selectively boost the contrast
using a proprietary algorithm that enhances contrast between pixel
values crowded in a narrow range of value, usually near the
background level. This works with intensity images but not with RGB
images. This feature was added to Mira Pro x64 version 8.66.
|
Gamma Slider
|
Sets the gamma value when Gamma Stretch is selected.
|
Min Z
|
Specifies the minimum Z (intensity) value. This is
active only when the Specify Z
Stretch is selected.
|
Max Z
|
Specifies the maximum Z (intensity) value. This is
active only when the Specify Z
Stretch is selected.
|
Min %
|
Specifies the minimum percentile intensity. This
is active only when the Percentile
Stretch is selected.
|
Max %
|
Specifies the maximum percentile intensity. This
is active only when the Percentile
Stretch is selected.
|
Contrast
|
Specifies the contrast value when the Autoscale Stretch is selected.
