Constructor Detail

GliderImage

public GliderImage(String name,
                   ImageUtil.AlignedImage alignedImage,
                   double altitude)

Construct an image from a file or BufferedImage and an arbitrary bounding region.

Parameters:

name - A unique name to identify the image. If the image source is a file, the file path can be used as the name.

alignedImage - An aligned image containing a BufferedImage and a Sector specifying the image and the location to place it.The image will be stretched as necessary to fully fill the region.

altitude - The altitude at which to display the image. Specify 0 to have the image draped over the globe's surface.

Throws:

IllegalArgumentException - if any of the first three arguments are null.

GliderImage

public GliderImage(String imageSource,
                   Iterable<? extends LatLon> corners,
                   double altitude)

Construct an image from a file.

Parameters:

imageSource - The path to the source image. Images can be any of those supported by ImageIO, as well as uncompressed TIFF images..

corners - The lat/lon locations of the region in which to map the image. The image will be stretched as necessary to fully fill the region. The locations must be specified in counterclockwise order beginning with the lower-left image corner.

altitude - The altitude at which to display the image. Specify 0 to have the image draped over the globe's surface.

Throws:

IllegalArgumentException - if any of the first three arguments are null.

GliderImage

public GliderImage(String name,
                   Object imageSource,
                   Iterable<? extends LatLon> corners,
                   double altitude)

Construct an image from a file or BufferedImage and an arbitrary bounding region.

Parameters:

name - A unique name to identify the image. If the image source is a file, the file path can be used as the name.

imageSource - Either the file path to the source image or a reference to the BufferedImage containing it. Images can be any of those supported by ImageIO, as well as uncompressed TIFF images.

corners - The lat/lon locations of the region in which to map the image. The image will be stretched as necessary to fully fill the region. The locations must be specified in counterclockwise order beginning with the lower-left image corner.

altitude - The altitude at which to display the image. Specify 0 to have the image draped over the globe's surface.

Throws:

IllegalArgumentException - if any of the first three arguments are null.

Method Detail

addRegionOfInterest

public void addRegionOfInterest(GliderRegionOfInterest region)

Adds a region of interest to display on the image.

Parameters:

region - the region of interest to add.

Throws:

IllegalArgumentException - if region is null.

alignImage

public static ImageUtil.AlignedImage alignImage(BufferedImage sourceImage,
                                                float[] latitudes,
                                                float[] longitudes)
                                         throws InterruptedException

Reprojects an image into an aligned image, one with edges of constant latitude and longitude.

Parameters:

sourceImage - the image to reproject, typically a non-aligned image

latitudes - an array identifying the latitude of each pixels if the source image. There must be an entry in the array for all pixels. The values are taken to be in row-major order relative to the image -- the horizontal component varies fastest.

longitudes - an array identifying the longitude of each pixels if the source image. There must be an entry in the array for all pixels. The values are taken to be in row-major order relative to the image -- the horizontal component varies fastest.

Returns:

a new image containing the original image but reprojected to align to the sector. Pixels in the new image that have no correspondence with the source image are transparent.

Throws:

InterruptedException - if any thread has interrupted the current thread while alignImage is running. The interrupted status of the current thread is cleared when this exception is thrown.
