Method Detail

drawBitmap

public static java.awt.image.BufferedImage drawBitmap(Bitmap bitmap,
                                                      int width,
                                                      int height)

Draws a Bitmap instance as a BufferedImage.

Parameters:

bitmap - The bitmap to draw.

width - Number of bits to draw before wrapping to the next line

height - Number of scanlines in the bitmap

drawBitmap

public static java.awt.image.BufferedImage drawBitmap(Bitmap bitmap,
                                                      int width,
                                                      int height,
                                                      java.awt.Color color)

Draws a Bitmap instance as a BufferedImage with a particular color used to indicate the areas of the bitmap set to 1.

Parameters:

bitmap - The bitmap to draw.

width - Number of bits to draw before wrapping to the next line

height - Number of scanlines in the bitmap

color - Color to use for bits that are set to 1.

drawGeoavailabilityGrid

public static java.awt.image.BufferedImage drawGeoavailabilityGrid(GeoavailabilityGrid g)

Convenience function to draw a GeoavailabilityGrid as a BufferedImage.

Parameters:

g - GeoavailabilityGrid to draw

drawGeoavailabilityGrid

public static java.awt.image.BufferedImage drawGeoavailabilityGrid(GeoavailabilityGrid g,
                                                                   java.awt.Color color)

Convenience function to draw a GeoavailabilityGrid as a BufferedImage, with a specific color for the bits that are set to 1.

Parameters:

g - GeoavailabilityGrid to draw

color - Color to use for bits that are set to 1.

drawIterableMap

public static java.awt.image.BufferedImage drawIterableMap(java.util.Iterator<java.lang.Integer> it,
                                                           int width,
                                                           int height)

Given an iterator of integer indices in a bit set, this method will draw the visual representation of the set. This is useful for visualizing what a bitmap index or query polygon looks like.

Parameters:

it - Iterator of bit set indices.

width - Width of the output image.

height - Height of the output image.

Returns:

A BufferedImage with the visual representation of the bitset.

drawIterableMap

public static java.awt.image.BufferedImage drawIterableMap(java.util.Iterator<java.lang.Integer> it,
                                                           int width,
                                                           int height,
                                                           java.awt.Color color)

Given an iterator of integer indices in a bit set, this method will draw the visual representation of the set. This is useful for visualizing what a bitmap index or query polygon looks like.

Parameters:

it - Iterator of bit set indices.

width - Width of the output image.

height - Height of the output image.

color - Color of bits set to 1.

Returns:

A BufferedImage with the visual representation of the bitset.

imageToFile

public static void imageToFile(java.awt.image.BufferedImage image,
                               java.lang.String file)
                        throws java.io.IOException

Convenience function to write a BufferedImage to a file.

Throws:

java.io.IOException
