| RasterTreeBuilder | | public class RasterTreeBuilder (Code) | | This class represents a RasterTreeBuilder object.
It wcan be used to create a resolution pyramid from one or more already existing raster dataset
(image). The resulting pyramid will be described by a set of shapes (containing the image tiles
bounding boxes) and a XML coverage description document that can be used with the deegree WCS.
The RTB supports real images like png, tif, jpeg, bmp and gif as well as raw data image like
16Bit and 32Bit tif-images without color model.
because of the large amount of data that may be process by the RTB it makes use of a caching
mechnism. For this the ehcache project is used. One can configure the cache behavior by placing a
file named ehcache.xml defining a cache named 'imgCache' within the class root when starting the
RTB. (For details please see the ehcache documentation). If no ehcache.xml is available default
cache configuration will be used which is set to:
- maxElementsInMemory = 10
- memoryStoreEvictionPolicy = LFU
- overflowToDisk = false (notice that overflow to disk is not supported because cached objects
are not serializable)
- eternal = false
- timeToLiveSeconds = 3600
- timeToIdleSeconds = 3600

interpolation - |
| drawImage | | public static void drawImage(BufferedImage out, float[][] data, TiledImage image, Tile tile, WorldFile wf, double minimumRes, Interpolation interpolation, Map<String, String> imageFilesErrors, String outputFormat, int bitDepth, float offset, float scaleFactor)(Code) | | Draws an image map to the target tile considering defined interpolation method for rescaling.
This method is static so it can be used easily from the RasterTreeUpdater.
Parameters:
out - target image tile
Parameters:
data -
Parameters:
image - source image map
Parameters:
tile - tile description, must contain the envelope of the target image
Parameters:
wf - must contain the envelope of the TiledImage of the source image
Parameters:
minimumRes - the minimum resolution of input images
Parameters:
interpolation - the interpolation method
Parameters:
imageFilesErrors - a mapping between image files and errors
Parameters:
outputFormat - the output format
Parameters:
bitDepth - the output bit depth
Parameters:
offset - offset used if bitDepth = 16 and outputFormat = raw
Parameters:
scaleFactor - scale factor used if bitDepth = 16 and outputFormat = raw |
