Method Detail

getMinMaxRasterValue

public static Range getMinMaxRasterValue(double[] rasterData,
                                         RasterImageLayer rasterImageLayer)

Method to return the min value of a RasterImageLayer

Parameters:

rasterData - raster data as a 1-dimension double array

rasterImageLayer - source RasterImageLayer

Returns:

the min-max range of values in the Raster

getAlpha_0_255Range

public static int getAlpha_0_255Range(int range_0_100_Value)

Method to convert the transparency value from 0-100 range (0 means that the color is completely opaque and 100 the color is completely transparent) to 0-255 range (0 menas that the color is completely transparent and 255 that the color is completely opaque)

Parameters:

range_0_100_Value - transparency value in a 0-100 range

Returns:

an opacity value in a 0-255 range

getAlpha_DecimalRange

public static float getAlpha_DecimalRange(int range_0_100_Value)

setGradientPanel

public void setGradientPanel(JPanel panel,
                             ColorMapEntry[] colorMapEntries)

Method for displaying in a panel a gradient

Parameters:

panel - Panel on which display the gradient

colorMapEntries - Colors that make up the gradient. The quantity element in ColorMapEnty[] must have values from 0 to 1, in ascending order and whitout repetition.

round

public static double round(double value,
                           int decimalPlace)

Method to round a double value to a certain number of decimal place

Parameters:

value - Value to be rounded

decimalPlace - number of decimal places

Returns:

rounded value

createStandardGradientComboBox

public static GradientComboBox createStandardGradientComboBox(int width,
                                                              int height)

clearRasterStylerFromBlackBoard

public static void clearRasterStylerFromBlackBoard(WorkbenchContext context)

Method to delete the RasterStylesDialog about a raster from the BlackBoard. The method checks and deletes the properties about RasterStylesDialog for rasters that are no more loaded on the TOC.

Parameters:

context - the WorkbenchContext

updateGradientComboBoxes

public static void updateGradientComboBoxes(ColorMapEntry[] colorMapEntries,
                                            int width,
                                            int height)

Method to update gradientComboBoxes with new ColorMapEntry. All gradientComboBoxes must have the same width anf height.

Parameters:

colorMapEntries - new colors for gradient

width - width of gradientComboBoxes

height - height of gradientComboBoxex

addGradientComboBoxToList

public static void addGradientComboBoxToList(GradientComboBox gradientCB)

Method to memorize in a List the GradientComboBoxes

Parameters:

gradientCB - GradientComboBox to add to List

getBBKey

public static String getBBKey(String rasterPath)
