ColorMap Tutorial
The colormap module allows the user to change what colors are assigned to
what values in the data. The user has control over the hue, saturation,
value, and opacity for the data that is being inputted to the module.
The simplest network that uses autocolor is one that uses import to get the data, which outputs its data to
the Colormap module. The output of colormap is then attached to a
color module to define specific colors to values.
Inputs :
DATA - object used to derive the min and max
MIN - minimum of colormap range
MAX - maximum of colormap range
NBINS - number of bins in the histogram
COLORMAP - RGB colormap to be used
OPACITY - opacity map to be used
TITLE - title for the colormap editor window
Outputs :
RGB - the RGB field
OPACITY - the opacity field
Configuration Screen:
The colors assigned to values can be modified simply by clicking on each
of the sections a modifying the line. For example if you wanted modify
the saturation so that it went from max to min as the values increased,
you would drag the control point at the top of the saturation box to the
left.
Example Program for ColorMap:
In this example we use an import module to get our data, it is mapped to a
plane, and is then colored by the color module which recieves color
information from colormap (note: the colormap has no data inputted, the
min and max are set.) the colormap information is also sent to the
Colorbar module which constructs a colorbar using the information provided
by colormap. Both of these outputs are collected and then displayed.
