Toolbar
Layout
The main
toolbar for the data reader is discussed below:
 |
|
| |
Information
includes: Array dimensions, min and max real values,
number of NaN's, number of positive infinites, and number
of negative infinites.
|
| |
|
| |
Colormap
selection:
|
Allows
user to select the colormap used to display the data.
Above image is rendered in the "Gray" colormap.
Image below is same scene rendered in the "HotCold"
colormap. |
| |
Lo Bound:
|
The
setting of the minimum bound of the colormap. Any value
in the data that is less than this will be rendered by
the out-of-bounds lo color. |
| |
Hi Bound:
|
The
setting of the maximum bound of the colormap. Any value
in the data that is greater than this will be rendered
by the out-of-bounds hi color. |
| |
Apply Exponent:
|
Applies
a floating point exponent to the data and re-renders.
This is useful when data is clustered in upper or lower
regions of the distribution. |
| |
Apply Changes:
|
Apply
any changes made to in the Adjustments window. |
| |
Use Scaled
Colormap:
|
Clears
any bounds set by user and scales colormap to span the
real part of the data. |
| |
Reset Data
Array:
|
Reloads
original data to remove any exponents applied to data
or any resampling done. |
| |
|
|
| |
Colormap
Style:
|
Shows
the progression of colors in the current colormap. |
| |
OOB Lo:
|
Shows
the color(s) that data that is out of bounds low will
be rendered with. |
| |
OOB Hi:
|
Shows
the color(s) that data that is out of bounds hi will be
rendered with. |
| |
NaN Color:
|
Shows
the color that NaNs will be rendered with. |
| |
Pos. Inf.
Color:
|
Shows
the color that positive infinity will be rendered with. |
| |
Neg. Inf.
Color:
|
Shows
the color that negative infinity will be rendered with. |
| |
Median
Color: |
Show
the color that is at the absolute middle of the colormap.
Also when a single value search is used, this is the color
that matching values are returned as. |
| |
Show
Colormap Window: |
Displays
the colormap editing window. |
| |
|
|
| |
Stretch:
|
Scales
the data to the current size of the window. |
| |
Actual Sz:
|
Displays
the data in its actual size per pixel. |
| |
Zoom Factor:
|
User
can set a zoom factor in the textbox from (1-1000%) |
| |
|
|
| |
New Height:
|
The
number of vertical pixels in the resampled image. |
| |
New Width:
|
The
number of horizontal pixels in the resampled image. |
| |
Resample: |
Initiates
the resampling process. |
| |
|
|
| |
Histogram:
|
The
picture window shows a low resolution sample of the input
data's histogram. |
| |
Show Stat
Window:
|
Pressing
this button will show the statistics window. (This is
discussed in detail below) |
|
Statistical
Window
The statistical
window is intended to allow the user to see a histogram of the current
data set and some other basic statistical data. The histogram of
the GoldenGate.jpg file is shown below. The color of the
histogram coincides with the coloring of the data in the image window.
This correspondence can be used to associate a given histogram spike
with a region of data in the image. Notice the pale green spike
in the histogram relates to the water in the image.
Histogram
of GoldenGate.jpg displayed in matching colormap
The layout
of the statistical window is shown below:
 |
|
| |
Max: |
Maximum
real value in the data |
| |
Min: |
Minimum
real value in the data |
| |
#
+Inf: |
Number
of positive infinities in the data |
| |
#
-Inf: |
Number
of negative infinities in the data |
| |
#
NaNs: |
Number
of NaNs in the data |
| |
Statistical
Distribution: |
The
statistical distribution selector is not yet implemented.
This is intended to allow user to switch between different
types of statistical distributions and see associated
parameters. Currently only Gaussian is supported. |
| |
Avg: |
Average
value of the real data |
| |
Std
Dev: |
Standard
deviation of the real data |
| |
|
|
| |
Background
Color: |
The
background color toolbar is not yet implemented. This
is intended to all the user to select the background color
of the histogram to maximize readability for a given colormap.
Currently the background color that is used is the NaN
color from the selected colormap. |
| |
#
Bins: |
Number
of discreet bins to split the histogram data into. |
| |
Lo
Bound: |
Low
bound of the data that is to be histogrammed. Any data
below this threshold will be excluded from the histogram. |
| |
Hi
Bound: |
High
bound of the data that is to be histogrammed. Any data
above this threshold will be excluded from the histogram. |
| |
|
|
| |
The data
equation function is not yet implemented. The intent
of this is to be able to run a series of basic math
operations on the data and display the results. The
matrix operations are all implemented in the general
matrix library, but the equation parser has not been
written.
|
| |
|
| |
Apply changes,
reset data to original format, and close statistics
window operations.
