org.das2.graph.DasColorBar.Type

enumeration of the types of colorbars.

Type( String desc, int[] colorTable )

create a new color table Type.

COLOR_WEDGE

Rainbow colorbar used by default. TODO: this is a misnomer, where color_wedge was the type of object in das1, not the instance of the type, and this should be renamed to "rainbow"

APL_RAINBOW_BLACK0

rainbow colorbar used at APL that has black at the bottom.

APL_RAINBOW_WHITE0

rainbow colorbar used at APL that has white at the bottom.

APL_COLOR_QUANTIZATION

Colorbar to make adjacent values distinct (particularly useful for Color Scatter plots).

GSFC_RP_SPECIAL

rainbow colorbar introduced for use at Goddard Space Flight Center.

MATLAB_JET

Mimic the default Matlab colorbar for comparison with Matlab-generated spectrograms.

MATLAB_JET_BLACK0

Mimic the default Matlab colorbar for comparison with Matlab-generated spectrograms, but with black for the bottom most color.

MATLAB_HSV

Mimic the default Matlab colorbar HSV.

BLUE_TO_ORANGE

BLUE_WHITE_ORANGE

blue-white-orange is a modified BLUE_TO_ORANGE, but visits white in the middle. Requested by iwc.

BLUE_GREEN_WHITE_YELLOW_RED

blue-green-white-yellow-red was provided by iwc.

RED_CYAN_BLUE_YELLOW_RED

modulo colorbar has same start and end, so it can be used to show angles.

GRAYSCALE

gray scale with white at the minimum (bottom) and black at the maximum.

INVERSE_GRAYSCALE

gray scale with black at the minimum (bottom) and white at the maximum.

WRAPPED_COLOR_WEDGE

rainbow that wraps around so that the top and bottom are the same color, When used with care this is useful for spaces that wrap around (modulo), such as longitude.

BLUE_BLACK_RED_WEDGE

colorbar with black in the middle, blue at the minimum and red at the maximum for showing deviations from the center.

BLUE_WHITE_RED_WEDGE

colorbar with white in the middle, blue at the minimum and red at the maximum for showing deviations from the center.

BLACK_RED

black to red, introduced to show the red component of RGB images

BLACK_GREEN

black to green, introduced to show the green component of RGB images

BLACK_BLUE

black to blue, introduced to show the blue component of RGB images

WHITE_RED

white to red, introduced to show grayscale-like image with color for comparisons

WHITE_GREEN

white to green, introduced to show grayscale-like image with color for comparisons

WHITE_BLUE

white to blue, introduced to show grayscale-like image with color for comparisons

WHITE_BLUE_BLACK

white to blue to black

INVERSE_WHITE_BLUE_BLACK

black to blue to white

VIOLET_YELLOW

Violet -Yellow

SCIPY_PLASMA

SciPy Plasma

AJ4CO_RAINBOW

AJ4CO_RAINBOW for Radio JOVE community

getColorCount

getColorCount( ) → int

Return the number of colors in the color bar. Fill (gray) is an additional color, and it's understood that the colors indeces from 0 to getColorCount()-1 are the color wedge, and getColorCount() is the fill color.

Returns:

the number of colors.

makeColorTable

makeColorTable( int[] index, int[] red, int[] green, int[] blue, int ncolor, int bottom, int top ) → int

returns a color table with interpolated colors for the wedge from 0 to ncolor-1, and at ncolor, the fill color.

Parameters

index - set of indeces that are control points for interpolation, including 0 and ncolor-1.
red - the red value from 0 to 255 at each index
green - the green value from 0 to 255 at each index
blue - the blue value from 0 to 255 at each index
ncolor - number of colors, typically COLORTABLE_SIZE=240.
bottom - the bottom, typically 0.
top - the top, typically COLORTABLE_SIZE=240.

Returns:

an array of RGB colors.
